This is a great snack for the kids. I used the silicone mold, which was great, because they were already cut when I popped them out of the mold. And they took less time to cook, due to the small size. If you are using a larger pan, the cook time will increase.
Start by creaming the sugars and the butter. Combine well.
Then mix in the espresso powder, eggs, vanilla, flour, baking soda, salt mix well.
Fold in the chocolate chips and nuts
Once everything is well mixed.
Press the dough into the pan, or silicone mold.
Set your air fryer at 310 degrees F, air fryer setting for 10 to 15 minutes.Then check them, then add another 15 minutes.At this point, my brownies were done, but the actual cooking time will depend on the wattage of your air fryer and the thickness of the brownie mold you use.
Plate, serve, and enjoy!
