# What You Need:

→ Wet Ingredients

01 - 2 tbsp creamy peanut butter
02 - 1 tbsp unsalted butter, melted

05 - 1/2 tsp vanilla extract

07 - 2 tbsp granulated sugar
08 - 1/4 tsp baking powder

# Step-by-Step:

01 - In a large microwave-safe mug, combine the peanut butter and melted butter. Stir until smooth.
02 - Add the egg, milk, and vanilla extract to the mug. Whisk with a fork until fully blended.
03 - Add flour, sugar, baking powder, and salt. Stir gently until just combined to avoid overmixing.

05 - Allow the cake to cool for 1 to 2 minutes before serving directly from the mug.

# Expert Advice:

01 -
  • It's genuinely done before you can pour a glass of milk, making it perfect for when hunger strikes at odd hours.
  • The peanut butter flavor is bold and rich without feeling heavy, somehow both decadent and oddly comforting in a mug.
  • You only need one dish and a fork, which means nobody's judging you at midnight when you're too tired to clean.
02 -
  • Microwave wattage matters—some microwaves cook faster than others, so start at 60 seconds and add time in 5-second increments if needed because overcooking turns it into a dense sponge.
  • Don't stir the batter more than necessary; the moment you see no more dry flour, you're done, and this restraint is what keeps it from becoming tough.
03 -
  • If you like it denser, add an extra tablespoon of flour; if you want it more tender, use one less tablespoon and maybe add a teaspoon more milk.
  • Natural peanut butter makes a more sophisticated version, though it might separate slightly—just stir it back together and you're fine.
