# Required Ingredients:

→ Wet Ingredients

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

06 - 3 tablespoons all-purpose flour
07 - 2 tablespoons granulated sugar

# Preparation Steps:

01 - In a large microwave-safe mug, stir together the creamy peanut butter and melted unsalted butter until smooth.
02 - Add the large egg, milk, and vanilla extract to the mug and whisk thoroughly with a fork until well combined.
03 - Mix in the all-purpose flour, granulated sugar, baking powder, and salt. Stir gently until just combined, avoiding overmixing.
04 - Microwave the mixture on high for 60 to 75 seconds, until the cake has risen and the center is set. Avoid overcooking to maintain moistness.
05 - Allow the cake to cool in the mug for 1 to 2 minutes before eating directly from the mug.

# Expert Suggestions:

01 -
  • No bowls to wash, no waiting for the oven, and you can eat it straight from the mug while it's still warm.
  • It uses pantry staples you probably already have, so there's no excuse not to make it when the craving hits.
  • The texture comes out surprisingly light and tender, not rubbery or dense like some microwave cakes.
  • You can customize it endlessly with chocolate chips, honey, or even a swirl of jam before microwaving.
02 -
  • Use a mug that holds at least 12 ounces, or the batter will overflow and make a mess in your microwave.
  • Don't cook it longer than 75 seconds or it will turn dry and rubbery. The center should look barely set when you stop the microwave.
  • Let it cool for at least a full minute before tasting, because molten peanut butter cake will absolutely burn your mouth.
03 -
  • Use a clear glass mug so you can watch the cake rise through the side and catch it at the perfect moment.
  • If your microwave has a turntable, place the mug slightly off center so it rotates through different heat zones for more even cooking.
  • Stir the batter in the mug itself to save dishes, but make sure you scrape the bottom corners where flour likes to hide.
