Ingredients

  • ¼ cup oat flour (or gluten free all-purpose flour)
  • ½ tsp baking powder
  • pinch of salt
  • 3 Tbsp fruit mash/puree (banana, applesauce, or pumpkin)
  • 1-2 Tbsp sweetener, to taste (maple syrup, honey, or granulated sugar)
  • 1 Tbsp nut butter
  • 1 Tbsp milk of choice

Optional Flavorings & Mix-Ins

  • tsp cinnamon
  • tsp vanilla extract
  • 2 tsp mix-ins (chocolate chips, nuts, sprinkles, etc.)
  • whatever you like!

Instructions

  • In a bowl, whisk together dry ingredients (flour, baking powder, salt & seasonings).
  • Separately, mix wet ingredients (fruit mash/puree, sweetener, nut butter, milk, and optional vanilla).
  • Gently fold dry ingredients into wet mixture, until integrated. Stir in any desired mix-ins.
  • Spray inside of mug (14-16oz) with cooking spray. Add mug cake 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 ou tclean.
  • 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 gluten free 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.
