Choosing The Right Pan

It's essential to choose the right type and size of pan to ensure even cooking and prevent any issues. Here are some tips for selecting the right baking pans:

1. Material

  • Use a metal or glass baking pan or ceramic dish. These materials conduct heat well, which is crucial for even baking.
  • Avoid silicone or disposable aluminum pans as they may not distribute heat evenly.

2. Size

  • The size of the pan should fit comfortably within your toaster oven. Most toaster ovens have interior dimensions that can accommodate a pan or dish that's roughly 9 to 11 inches (23 to 28 cm) in length and 6 to 8 inches (15 to 20 cm) in width.
  • It's important to measure the interior dimensions of your toaster oven to determine the largest pan that will fit without touching the oven walls or heating elements.

3. Depth

  • Choose a pan with sides that are at least 1 to 2 inches (2.5 to 5 cm) high.
  • This depth allows for the brownie batter to rise and create the desired thickness for your brownies.

4. Shape

  • A square or rectangular pan is ideal for traditional brownies.
  • An 8x8-inch (20x20 cm) or 9x9-inch (23x23 cm) square pan is a common choice.
  • You can also use a 9x6-inch (23x15 cm) rectangular pan.

5. Greasing & Lining

  • Regardless of the pan you choose, it's a good practice to either grease it with butter or cooking spray or line it with parchment paper.
  • This prevents the brownies from sticking to the pan and makes for easier removal and cutting.

Baking Brownies In A Toaster Oven: Do's & Don'ts

Baking brownies in a toaster oven can be a convenient and fun experience, but it does come with some specific do's and don'ts:


1. Preheat Your Toaster Oven: Just like with a regular oven, it's essential to preheat your toaster oven to the recommended temperature before placing your brownies inside. This ensures even baking.

2. Use An Appropriate Pan: Choose a baking pan or dish that fits comfortably inside your toaster oven. Using one that's too large may result in uneven cooking.

3. Line or Grease The Pan: To prevent your brownies from sticking to the pan, either grease it or line it with parchment paper before pouring in the batter.

4. Monitor Closely: Toaster ovens can vary in temperature and cooking times, so keep a close eye on your brownies, especially during the last few minutes of baking. Use a toothpick or cake tester to check for doneness.

5. Rotate The Pan: If you notice uneven cooking or hot spots in your toaster oven, consider rotating the baking pan halfway through the baking time for more consistent results.

6. Let Them Cool: After baking, allow your brownies to cool in the pan for a while before removing them. This helps them set and makes cutting neater.


1. Don't Overcrowd The Toaster Oven: Avoid baking multiple pans of brownies simultaneously unless your toaster oven has multiple heating elements and offers even heat distribution.

2. Don't Skip Preheating: Skipping the preheating step can result in undercooked or unevenly cooked brownies.

3. Don't Forget To Adjust Timing: A toaster oven heats faster, so it requires slightly shorter cooking times than a conventional oven. Keep a watchful eye on your brownies and adjust the timing accordingly to prevent overbaking.

4. Don't Use High Heat Settings: Avoid using excessively high heat settings as this can lead to burnt edges and an undercooked center.

5. Don't Open The Door Repeatedly: Opening the toaster oven door frequently during baking causes temperature fluctuations, leading to uneven results. Try to minimize door opening until you need to check for doneness.

6. Don't Leave Out The Cooling Step: Let your brownies cool in the pan before attempting to cut them. Cutting them while hot can lead to messy, crumbly slices.

By following these tips, you can make delicious brownies in your toaster oven with confidence and achieve consistently good results.
