Fluffy peanut butter cake with creamy texture, ready in minutes using simple ingredients.

# What You’ll Need:

→ Wet Ingredients

01 - 2 tbsp creamy peanut butter
02 - 1 tbsp unsalted butter, melted
03 - 1 large egg
04 - 2 tbsp milk (dairy or non-dairy)
05 - 1/2 tsp vanilla extract

06 - 3 tbsp all-purpose flour
07 - 2 tbsp granulated sugar
08 - 1/4 tsp baking powder
09 - Pinch of salt

# How-To:

01 - In a large microwave-safe mug, mix peanut butter with melted butter until smooth.
02 - Add egg, milk, and vanilla extract; whisk thoroughly with a fork until homogeneous.
03 - Stir in flour, sugar, baking powder, and salt until just combined; avoid overmixing.
04 - Cook on high power for 60 to 75 seconds until the mixture rises and the center is set; avoid overcooking.
05 - Allow to rest for 1 to 2 minutes before enjoying directly from the mug.

# Expert Hints:

01 -
  • A genuine dessert emerges from your microwave in the time it takes to brew tea, no pans or extra cleanup required.
  • The peanut butter flavor hits rich and satisfying without that dense, heavy feeling you get from store-bought treats.
  • You can eat it straight from the mug while it's still warm and slightly gooey, which honestly changes everything.
02 -
  • The difference between perfectly fluffy and dense comes down to not stirring the dry ingredients more than necessary; your instinct will be to keep mixing, but resist it.
  • Microwaves vary wildly in power, so the first time you make this, check at 60 seconds rather than setting a timer and walking away.
03 -
  • Using room-temperature peanut butter instead of straight from the cold jar makes it stir more smoothly into the butter without needing extra mixing.
  • If your cake rises but feels wet in the absolute center when you test it, give it another 15 seconds rather than assuming it's overdone; the residual heat keeps cooking it.
