Ingredients

Scale

Wet Ingredients

  • 1 1/2 tbsp butter, melted
  • 1 1/2 tbsp peanut butter
  • 1 egg yolk
  • 1 1/2 tbsp milk
  • 1/8 tsp vanilla extract (optional)

Dry Ingredients

  • 2 tbsp flour
  • 2 tbsp brown sugar
  • 1/8 tsp baking powder
  • Pinch of salt

Toppings (Optional)

  • Vanilla frosting
  • Crushed peanuts

Instructions

  1. Melt and combine wet ingredients: Start by melting the butter directly in the mug. Once melted, add the peanut butter and stir until smooth and combined. Next, add the egg yolk, brown sugar, salt, milk, and optional vanilla extract, stirring well until all ingredients are evenly mixed.
  2. Add dry ingredients: Incorporate the flour and baking powder into the wet mixture, stirring continuously until the batter is completely smooth with no lumps.
  3. Microwave cooking: Place the mug in the microwave and cook on high power for 60 seconds. Check to ensure the cake has set; it should be moist but cooked through.
  4. Optional topping: Once cooked, top the warm mug cake with vanilla frosting and sprinkle crushed peanuts on top for added texture and flavor. Enjoy immediately.

Notes

  • Ensure not to overcook the mug cake in the microwave to avoid dryness.
  • Using peanut butter with no added sugar can adjust sweetness to your preference.
  • You can substitute brown sugar with coconut sugar or white sugar if preferred.
  • Vanilla extract is optional but enhances flavor.
  • Mix ingredients thoroughly to prevent lumps in the batter.
  • Use a microwave-safe mug to avoid hazards.
