Peanut Butter Mug Cake


  • Author: Martha
  • Total Time: 5 minutes

Ingredients

Scale
  • 3 tablespoons peanut butter (creamy or chunky)
  • 1 tablespoon butter, melted
  • 1/4 cup milk (dairy or non-dairy)
  • 1/4 cup all-purpose flour
  • 1/4 teaspoon baking powder
  • 1 tablespoon brown sugar (or granulated sugar)
  • 1/4 teaspoon vanilla extract
  • A pinch of salt

Instructions

Prepare the Mug Cake

  1. Combine Wet Ingredients: In a microwave-safe mug, add the peanut butter, melted butter, milk, and vanilla extract. Stir until smooth and well combined.
  2. Mix Dry Ingredients: Add the flour, baking powder, brown sugar, and salt to the mug. Mix until all the ingredients are fully incorporated, and the batter is smooth.
  3. Microwave: Microwave the mug on high for 1 minute and 30 seconds to 2 minutes, depending on the strength of your microwave. Keep an eye on the cake while it cooks—if it overflows, stop the microwave and let it settle before continuing.
  4. Check for Doneness: The mug cake should rise and firm up, but still have a soft, gooey center. If the top is set, it’s done!

Serve and Enjoy

  1. Let It Cool: Allow the mug cake to cool for about 1 minute before digging in—it will be very hot!
  2. Toppings (Optional): For an extra treat, top your mug cake with whipped cream, a drizzle of melted chocolate, a few chocolate chips, or a scoop of vanilla ice cream.
