Black+Decker Convection (CTO6335S) vs Black and Decker 4 Slice Toaster Oven Side-by-Side Comparison




Our Verdict
- Performance (50%)7.0/10
- Design (25%)6.6/10
- Usability (25%)6.1/10
- Performance (50%)6.1/10
- Design (25%)4.6/10
- Usability (25%)5.5/10
The match between Black+Decker Convection Toaster Oven (CTO6335S) and the Black and Decker 4 Slice Toaster Oven (TO1760SS) is quite literally a sibling rivalry. Comparing two models of the same brand really highlights the common advantages that a large unit has as opposed to a small one.
The convection model has an overall score one point higher than the 4-slice and also across the board including design, usability, and performance. Moreover, it doesn’t even cost that much more, not even twice as much.
The TO1760SS has a standard design with two quartz heating elements and three analog control dials. On the other hand, the CTO6335S four quartz heating elements and a digital control panel with buttons for cooking presets, convection toggle, and more precise timer and temperature adjustment.
Having a convection system and a higher power output, the CTO6335S was able to toast bread, bake pizza, roast whole chicken, and bake fries in a shorter amount of time while getting better color and crispiness than the TO1760SS. Its larger cooking chamber also made cooking less of a mess and therefore, easier to clean.

Toast




- Function: Toast
- Number Of Slices: 4
- Toast Level: 4/7
- Cooking Time: 5m 10s
- Second Batch: 3m
- Convection: No
With our Toast test, we were able to determine that level 4—5 minutes 10 seconds on the timer—was the best option scoring a 7/10. Levels 3 and 5 respectively had a lighter and darker than ideal, although even, surface color.
The toast level 4 of the Black+Decker scored a 7/10 for color. The four pieces had areas of different colors ranging from golden brown to just slightly golden. This was probably due to uneven heating of the elements and the convection fan not running.
Despite the color, the first batch was crispy on the outside and soft on the inside so we gave it a 7.5/10 for taste. Our head chef Tuyet Pham determined that it would go great with eggs benedict and omelet.
Even with the automatic toast time adjustment feature, the quality of the second batch was reduced in every aspect. The color was lighter and the texture was less crispy so we had to give it a 6/10 for consecutive usability. If you want the second batch to be the same as the first, lower the toast level by one.




- Function: Toast
- Number Of Slices: 4
- Toast Level: 3/4 to Medium
- Cooking Time: 4m
- Second Batch: 4m
- Convection: No
At the beginning of our Toast test, we turned the toast knob to the Medium Toast icon/setting—around 4 minutes 10 seconds on the timer—which resulted in four slightly burnt pieces of bread. We then chose the setting between Medium and Light, which was around 3 minutes 25 seconds on the timer, but that wasn’t enough time to get an even surface color.
Finally, we figured that around 4 minutes on the timer would yield the best possible result, with a total score of 7.1/10. Since it used an analog control knob, it was quite tricky to precisely choose 4 minutes, and we had to use an external timer.
On this setting, the Black+Decker produced four pieces of toast with a brown-colored top. However, the bottom was slightly charred in some areas and lacked color in others, so we gave the toast a 6.5/10 for even surface color.
Fortunately, the toast was crispy on the outside while still soft and moist on the inside, deserving a 7.5/10 for taste. Our head chef Tuyet Pham concluded that it would go great with omelets and eggs benedict, but not so much with soups or sandwiches.
For some reason, despite the identical toasting time, the second batch had a more uneven surface color than the first. The toast had a slightly darker color and crispier texture, which is more suitable for soups, and scored a 6.8/10 for consecutive usability.
Pizza




- Function: Bake
- Temperature: 450°F
- Cooking Time: 7m 30s
- Convection: Yes
The Black+Decker did an ok job of baking a 9-inch thick-crust meat pizza earning it a 6.8/10.
Compared to the recommended 10 minutes on the label, it took 7m 30s to bake the pizza, which was fairly solid. However, after comparing it to other toaster ovens in our Pizza test, we could only give it a 7.5/10.
The crust had a good golden brown color but was soft and a little dry — possibly due to the longer cooking time. Thus, it could only get a 7/10.
The toppings were mostly dry with an uneven coloring, plus the cheese wasn’t melty so it got a 6.5/10.
In the end, our chef gave the pizza a 6.5/10 for taste.




- Function: Bake
- Temperature: 450°F
- Cooking Time: 13m
- Convection: No
The low power output of the Black+Decker held it back in our Pizza test, where a high temperature of 450 °F was required; it scored a 5.6/10. The oven took 13 minutes to bake a 9-inch thick-crust meat pizza, which was longer than our time limit of 10 minutes, resulting in a 0/10.
Fortunately, the other aspects were quite solid, even though the oven’s internal temperature couldn’t be maintained at 450 °F. The crust had a nice golden color but it was a bit soft, so it got a 7/10.
The toppings had reasonably even caramelization throughout and the cheese was slightly melted—enough to score another 7/10. Taking the crust and toppings into account, our chef gave the pizza one last 7/10 for taste.
Whole Roasted Chicken





- Function: Bake
- Temperature: 350°F
- Cooking Time: 1h
- Convection: Yes
Following our Whole Roasted Chicken test guidelines, we placed a 3 lb chicken on a broiling rack on a baking pan of the Black+Decker with plenty of space to spare. The abundance of space gave it some advantages over smaller units like the Breville BOV450XL despite a lower power output. Overall, the Black+Decker received a 7.7/10 for this test.
It took the oven 1 hour, the standard amount of time, to roast the chicken to a desirable color so we gave it an 8/10. The skin came out a light golden color but it was uneven despite being flipped after the first 40 minutes. In addition, it was soft, so it got a 6.5/10.
The chicken was thoroughly cooked but the internal temperature was a tad bit high at 189°F-192°F compared to the USDA recommended 165°F-180°F so we gave it an 8.8/10. The meat was very juicy but the lack of roasted aroma and crispy skin resulted in a 7.5/10 for taste from our chef.






- Function: Bake
- Temperature: 350°F
- Cooking Time: 1h 30m
- Convection: No
During our Whole Roasted Chicken test, the 3 lb chicken touched the upper heating element’s guard. This heavily seared the middle part of the chicken and made a mess inside the cooking chamber. If you were to roast a chicken in this oven, we recommend cutting open the chicken or chopping it into pieces beforehand.
The final test score of 6/10 made us speculate that the oven’s lower output also hindered its performance, even though the required temperature was only 350°F. The Black+Decker took 1 hour 20 minutes to roast the chicken, compared to the standard one hour, so it got a 6/10.
The skin had almost no color, except for the areas near the upper heating element, and was still very soft; we could give it just a 5/10. That being said, increasing the cooking time further would reduce the score for the skin and risk overcooking the chicken.
The only upside to the long cooking time and low oven temperature was the doneness of the chicken. The meat had no pink areas and the chicken’s internal temperature was 185°F–187°F, which was very close to the USDA recommended 165°F–180°F.
This partially helped maintain the juiciness of the meat, but the unappetizing skin gave our chef no choice but to give the chicken a 5/10 for taste.
Baked French Fries




- Function: Bake
- Temperature: 400°F.
- Cooking Time: 25m 50s
- Convection: Yes
With a score of 5.6/10, the Black+Decker left a lot to be desired in the Baked French Fries test. In comparison, the same-sized Cosori CO130-AO did a much better job with its higher power output and air fry basket.
This oven took 25m 50s to bake 12 oz of fries which was just a bit too long over the limit of our Baked French Fries test. Thus, it failed our cooking time section. Coloring was uneven among the fries ranging from nicely golden to almost none so they could only get a 7/10.
The textures were also uneven and, worse, none was particularly good. The golden fries were only a little crispy and the ones that lacked color were soft. Overall, it was a 6.8/10 for this test.
Our chef gave the resulting fries a 7/10 for taste.




- Function: Bake
- Temperature: 400°F
- Cooking Time: 30 m
- Convection: No
While conducting our Baked French Fries test, the Black+Decker’s weakness in maintaining a high temperature became more apparent, and it scored a 3.2/10.
To start with, it took 30 minutes to bake 12 oz of frozen fries; this was way longer than our limit of 25 minutes and resulted in a score of 0/10. Despite the long time duration, the fries had almost no color, so we could only give it a 4/10.
The same can be said for the texture of the fries which was not crispy, earning it another 4/10. Overall, the fries appeared more boiled than oven-baked, so our chef had to give it one last 4/10 for taste.

Cooking Functions of the Black and Decker CTO6335S Digital Convection Toaster Oven

- Cookies
- Pizza
- Frozen snacks
- Potato
- Bake
- Broil
- Toast
- Bagel
The eight cooking functions are useful for beginners and experienced cooks can freely adjust the time and temperature of each to their liking.

- Toast
- Bake
- Broil
- Warm
The Black+Decker serves the three basic functions of a toaster oven: Toast, Bake, and Broil. If you know your way around the kitchen, Bake and Broil are all the functions you’ll need.
The Warm function maintains the oven at around 150°F, which is the common lowest temperature for most analog ovens. However, that’s a bit higher than most digital ovens’ warm function, which maintains around 100°F–-120°F.
Interior



- Heating Elements:4 quartz
- Convection Fan:Yes
- Lighting:No
- Tray Levels:2
- Rotisserie:No
- Safety Hook:No
The Black+Decker only has two tray levels but you can make use of the flippable rack to effectively create two more levels. The oven has a convection system but no internal lighting—unlike the Ninja DT201—which can be an inconvenience considering the interior is black.
The oven has quartz heating elements that use infrared light to cook. They have their own safety guards to prevent direct contact with baking pans and trays.
Compared to the more common nichrome heating elements, they produce more heat and cool down faster. They are also more energy-efficient and easier to clean but don’t last as long in terms of durability. However, if grease splashes onto the heating elements while cooking, it’ll leave permanent stains.




- Heating Elements:2 quartz
- Convection Fan:No
- Lighting:No
- Tray Levels:1
- Rotisserie:No
- Safety Hook:No
The TO1760SS has only one tray level, while most other same-sized units, including the Mueller MT-175, have at least two. Moreover, it doesn’t have an interior light or a convection system: two common weaknesses of small toaster ovens.
The oven has two quartz heating elements, which may not distribute heat as evenly as four or more will do. Nonetheless, they are easier to clean and more energy-efficient than the more common nichrome variety. However, if grease splashes onto the heating elements while cooking, it’ll leave permanent stains.
These heating elements use infrared light to cook, which makes the process quicker. They cool down faster too, but are not as durable.
Capacity

- Length:14.2" (36.0 cm)
- Width:12.6" (32.0 cm)
- Height:7.9" (20.0 cm)
The CTO6335S can comfortably fit 6 slices of toast, a 12-inch pizza, and a 3 lb whole chicken. While the manufacturer didn’t state the oven’s capacity, we measured the cooking chamber’s volume to be around 23 liters.

- Length:10.8" (27.5 cm)
- Width:8.7" (22.0 cm)
- Height:6.7" (17.0 cm)
The Black+Decker has a standard capacity for a small oven—10 liters, 4 slices of toast, a 9-inch pizza, and barely enough for a 3 lb chicken. This was one of the rare occasions where the cooking chamber’s volume that we measured matched the manufacturer’s stated capacity.
Power Cord the Black And Deck Convection Toaster Oven

- Length:24.8" (63.0 cm)
- Type:3-prong plug
- Power:1500 W
- Rated Output:120 V ~ 60 Hz
Even though the length of 24.8" is enough for household use, the power cord protrudes from the bottom of the oven reducing the usable length. In addition, it’s not long enough to wrap around the two back buffers.

- Length:25.6" (65.0 cm)
- Type:3-prong plug
- Power:1150 W
- Rated Output:120 V ~ 60 Hz
The power cord has a good length for household use—roughly 25.59". However, the oven doesn’t have any storage space for it.
Accessories

- Length:14.2" (36.0 cm)
- Width:10.0" (25.4 cm)
- Height:0.9" (2.2 cm)
- Material:Stainless steel
- Dishwasher Safe:Yes
The baking rack can be placed in the oven either way up, effectively adding two more tray levels for the oven.

- Length:10.8" (27.4 cm)
- Width:8.3" (21.2 cm)
- Height:0.6" (1.5 cm)
- Material:Stainless steel
- Dishwasher Safe:Yes
The baking rack fits perfectly with the guide, which helps prevent accidents when placing food in the oven.
Accessories

- Length:13.3" (33.8 cm)
- Width:10.2" (25.8 cm)
- Height:1.2" (3.0 cm)
- Material:Stainless steel
- Dishwasher Safe:Yes
The baking pan is large and, being 100% compatible with the broiling rack, it catches all the drippings. This prevents any hot mess from dirtying the heating elements thus mitigating that potential fire hazard. However, it’s not 100% non-stick so you may have some stubborn stains to deal with after a heavy roasting session.

- Length:9.0" (22.9 cm)
- Width:7.9" (20.0 cm)
- Height:0.6" (1.5 cm)
- Material:Stainless steel
- Dishwasher Safe:Yes
The baking pan rests on the supports of the baking rack, which saves a bit of space in the cooking chamber. However, this means the pan will be shorter in length than the rack.
The pan does the job of catching any meat juices and drippings. This helps prevent any mess and the risk of fire from dirty heating elements. However, it doesn’t have a good coating and thus sustained some stubborn stains after our Whole Roasted Chicken test.
Accessories

- Length:11.7" (29.7 cm)
- Width:8.7" (22.0 cm)
- Height:0.7" (1.9 cm)
- Material:Stainless steel
- Dishwasher Safe:Not advisable
The broiling rack is designed to fit the baking pan perfectly while the holes are there to help with air circulation around the food. It doesn’t have a coating though so it may be prone to stains, caramelized bits of food, and discoloration.

- Length:10.7" (27.2 cm)
- Width:7.7" (19.5 cm)
- Height:0.8" (2.0 cm)
- Material:Stainless steel
- Dishwasher Safe:Not advisable
Crumbs can be quite a hassle to clean up, but the removable crumb tray makes it easier to remove them from the oven’s floor. Nonetheless, be careful, as some crumbs may still fall to the bottom of the oven as you take the tray out of the oven.
Build Quality

The Black+Decker CTO6335S is equipped with a tamper-resistant screw to prevent removal of the outer cover. However, the bottom tray can easily slide out and the door can also open if you tilt the oven.
Throughout our tests, we noticed that the oven’s large capacity is somewhat counteracted by its power output of 1500 W. We speculated on its ability to perform more efficiently if it were 1800 W.

The Black+Decker has a sturdy build and is made from durable stainless steel. The dials turn smoothly and are polished for aesthetics and easy cleaning.
The oven, equipped with a tamper-resistant screw to prevent removal of the outer cover, contains no user-serviceable parts. This means you need to refer service to qualified service personnel if an issue crops up and not attempt self-repair.

User Control
The Black+Decker has 8 functions but the convection toggle is only applicable to Bake. There’s an indicator light for when a function starts and stops — which are two separate buttons on the control panel.
For all functions except Toast and Bagel, you can push the increment and decrement buttons once to change the temperature in increments of 5°F and hold to change in increments of 25°F. After pressing the Timer button, the same goes for cooking time but in increments of 1 minute and 10 minutes. For Toast and Bagel, simply choose a level from 1 to 7.
Unfortunately, even though the label shows a stay-on function, we couldn’t find it in the control panel or the user manual. A small thing we didn’t like about the buttons was that they sometimes didn’t respond well.
There are a few things to keep in mind when using Black+Decker’s three simple control knobs. For the timer knob, always rotate past 10 minutes and then rotate back to the desired time when setting it to less than 10 minutes.
It’s also tricky to accurately adjust time and temperature. Normally, you can use an oven thermometer and an external timer to get around this. However, if you check the pointer, you'll find that the temperature knob of this unit is off by around 50°F. Evidently, when we set the temperature to 450°F for our pizza test, the oven heated up to only around 405°F.
Ease of Use
For all functions except for Toast and Bagel, the Black+Decker has an automatic preheat feature. This will always heat the heating elements to 350°F, which takes around 4m 20s, before starting the actual timer. Then, the internal temperature will gradually stabilize around your input temperature.
One thing to note is that you cannot change the temperature or time during the automatic preheat cycle. You can only do so once the oven reaches the selected temperature.
Keep in mind that the oven’s exterior gets hot to the touch quite quickly. In addition, it doesn’t turn off upon opening the door, unlike some others. The door also can’t be opened partially.
This oven beeps with each push of a button and does so three times when it finishes cooking. The oven always remembers the last selected setting until it’s unplugged. It’s advised to unplug the oven after you finish using it as the digital display doesn’t turn off after a period of no interaction.
The manufacturer claims the Black+Decker has the EvenToast Technology™ which toasts bread 30% more evenly. However, we didn’t notice an increase in evenness in our Toast test. Their Natural Convection technology certainly didn’t change the fact that this unit doesn’t have the convection fan that comes with several advantages.
With three control knobs, it’s very simple to readjust cooking settings. The cooking cycle finishes when the timer reaches O (off). When this happens, the oven will ding once and shut off. As it has no digital display, you can freely leave this oven plugged in without worrying about power consumption.
It’s easy to keep the door partially open to let food cool down; however, be vigilant as the door can slide all the way down on the rare occasions when the oven is tilted. Opening the door doesn’t turn off the oven, unlike some other models.
Cleanability




We cleaned the Black+Decker following our toaster oven cleaning guide. With the oven having an internal and external coating, cleaning was quite straightforward.
However, even with the slide-out crumb tray, we still had to tilt the oven to get all of the crumbs out. In addition, some of them got stuck inside the heating element safeguards and we had no way of getting them out.



While the interior of the Black+Decker didn’t have a non-stick coating like the Breville BOV450XL, it was easy to clean because there were no tricky nooks and crannies. The removable crumb tray made it easy to clean up the crumbs, though we still had to tilt the oven to remove the last of them.
During our Whole Roasted Chicken test, the chicken touched the upper heating element’s guard and left some permanent discoloration there, even after we cleaned up the burnt bits. There were also some permanent stains on the cooking chamber’s ceiling.
