Ingredients
1 Tbs peanut butter
1 Tbs liquid egg white (or use a tablespoon of beaten egg, I just think liquid egg white is more convenient for this)
1 tsp dutch-processed unsweetened cocoa powder
1/8 tsp vanilla extract
1-2 packets sweetener such as stevia OR 1 Tbs honey
Pinch baking soda (about 1/16 tsp; you can try omitting this if you like a denser brownie.)
Pinch salt (can omit if your almond butter is salty)
Preparation
Mix ingredients in a mug and microwave for 30 seconds - 1 minute
