Ingredients

¼ cup oat flour (or gluten free/regular all-purpose flour)
½ tsp baking powder
pinch of salt
3 Tbsp mashed banana (~½ small banana)
1 Tbsp maple syrup (or granulated sugar, or honey)
1 Tbsp almond butter (or neutral nut butter)
1 Tbsp nondairy milk

Instructions

In a bowl, whisk together flour, baking powder, and salt.
Separately, combine mashed banana, sweetener, almond butter, and milk.
Gently fold dry ingredients into wet mixture, until integrated. (Fold in any desired mix-ins, if using.)
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.

You will need to experiment to find the right cook time in your microwave.
