Ingredients

¼ cup oat flour (or gluten free/regular all-purpose flour)
2 tsp cocoa powder unsweetened
½ tsp baking powder
pinch of salt
3 Tbsp applesauce
1½ Tbsp maple syrup (or honey, or granulated sugar)
1 Tbsp peanut butter (or neutral nut butter)
1 Tbsp nondairy milk
⅛ tsp vanilla extract
2 tsp mini vegan chocolate chips (optional)

Instructions

In a bowl, whisk together flour, cocoa powder, baking powder, and salt.
Separately, combine applesauce, sweetener, peanut butter, milk, and vanilla.
Gently fold dry ingredients into wet mixture, until integrated. Fold in mini chocolate chips if desired.
Spray inside of mug (14-16oz) with cooking spray. Add batter.
Microwave 2 minutes 45 seconds, or more/less depending on your microwave wattage. (I tested this recipe in my 900-watt microwave—see cook time guidance below and adjust for your microwave.) Test to see if a toothpick comes out clean.
Allow to cool 1 minute in mug. Place a plate on top of mug, then flip and tap mug with a spoon to remove mug cake. Rest 3-5 minutes before cutting and eating.
Best enjoyed immediately!

To make mug cake with an egg:

Replace 1 Tbsp nut butter + 1 Tbsp nondairy milk with 1 whisked egg.
When cooking, microwave for at least 15-20 seconds less as you test to find the right time in your machine.
