Step 1

Mix the dry ingredients together in one bowl. Then mix the wet ingredients in a large measuring cup. Add the wet to the dry and mix well.

Step 2

Add in the mix-in(s) of your choice and mix again.

Step 3

Preheat your air fryer to 350°F. Line a 5-inch round cake or pie pan (or a loaf pan that fits in your air fryer) with parchment paper. (Alternatively you can spray the pan with oil, but then the brownies will not be oil-free.)

Step 4

Place the pan in the fryer basket or on the tray if you have an oven-style air fryer. Cook for 20 minutes. If the middle is not well set or a knife doesn't come out clean when stuck in the middle, cook for 5 minutes more and repeat as needed. Cooking time may vary depending on the size of your pan and your particular air fryer.

Step 5

Let the brownies cool for about 30 minutes before cutting.
