A 3-ingredient microwavable protein brownie that's highly customizable.
Mix the dry ingredients in a bowl or mug. If you'd like to easily remove the brownie from the mug after cooking, transfer the protein brownie batter to a second mug or bowl sprayed with nonstick cooking spray.
Microwave for 1-1.5 minutes for a single recipe or 2-2.5 minutes for a double recipe. Depending on the size of your bowl, watch for overflow.
