2-Minute Peanut Butter Cake (Printable)

A quick microwave dessert delivering rich peanut butter flavor in a fluffy, single-serve cake.

# 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

→ Dry Ingredients

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

# How-To:

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

# Insider Tips:

01 -
  • It actually tastes indulgent, not like a shortcut or compromise.
  • You can have warm, homemade cake before you finish your coffee cup.
  • One mug means one dish, and honestly, that's half the appeal of late-night baking.
02 -
  • Overmixing is the fastest way to end up with a rubbery, dense cake, so resist the urge to stir too much once the flour goes in.
  • Every microwave cooks differently—60 seconds might be perfect in yours, or you might need the full 75, so watch it the first time to learn your machine's rhythm.
03 -
  • Room-temperature peanut butter mixes more smoothly than cold peanut butter straight from the fridge, so keep that jar out on the counter.
  • Don't walk away from the microwave—stand there and listen for the moment the bubbling becomes less aggressive, which means the cake is nearly done rising.
