# What you need:

→ 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

07 - 2 tablespoons granulated sugar
08 - 1/4 teaspoon baking powder
09 - Pinch of salt

# How to make it:

01 - In a large microwave-safe mug, mix the peanut butter and melted butter until smooth.
02 - Add the egg, milk, and vanilla extract to the mug, then whisk thoroughly with a fork until fully blended.
03 - Stir in the flour, sugar, baking powder, and salt until just combined, taking care not to overmix.
04 - Microwave the mixture on high for 60 to 75 seconds, or until the cake has risen and the center is set; avoid overcooking.
05 - Allow the cake to cool for 1 to 2 minutes before enjoying directly from the mug.

# Helpful Hints:

01 -
  • It's genuinely ready faster than you can order takeout, making it perfect for unexpected cravings or dessert emergencies.
  • One mug means one bowl to wash and zero guilt about making a full batch just for yourself.
  • The texture is surprisingly tender and fluffy, nothing like the dense microwave disasters you might be imagining.
02 -
  • Timing varies wildly between microwaves—the first time you make this, check it at 60 seconds and remember that 10 extra seconds can mean the difference between fluffy and rubbery.
  • Using room-temperature egg instead of cold egg helps everything incorporate faster and bake more evenly.
03 -
  • If your microwave is particularly powerful, start at 60 seconds and add time in 10-second increments rather than guessing and ending up with a rubbery cake.
  • Melting the butter first prevents it from clumping when mixed with the peanut butter, creating a smoother, more uniform batter.
