Description

This rich and fluffy Peanut Butter Cake Mug is the ultimate quick dessert. Made in minutes with pantry staples, it’s soft, nutty, and topped with a creamy swirl of peanut butter for extra indulgence.


Ingredients

Scale
  • 4 tablespoons self-rising flour
  • 3 tablespoons granulated sugar
  • 4 tablespoons creamy peanut butter
  • 3 tablespoons whole milk
  • 3 tablespoons salted sweet cream butter, melted
  • 1/2 teaspoon pure vanilla extract
  • 1 tablespoon creamy peanut butter (for garnish, optional)


Instructions

  1. In a microwave-safe mug, combine self-rising flour and granulated sugar.
  2. Add creamy peanut butter, whole milk, melted butter, and vanilla extract. Stir until fully combined and smooth.
  3. Optional: Drop 1/2 tablespoon of peanut butter in the center for a gooey core.
  4. Microwave on high for 60 to 70 seconds, checking for doneness. If needed, continue in 10-second increments.
  5. Let the cake cool slightly, then top with remaining peanut butter for garnish.
  6. Serve warm and enjoy straight from the mug.

Notes

  • Use a large mug to prevent overflow as the cake rises.
  • Microwaves vary — avoid overcooking to keep the cake soft.
  • To make your own self-rising flour, mix 4 tbsp all-purpose flour with 1/2 tsp baking powder and a pinch of salt.
