How to Make Peanut Butter Mug Cake

Step 1: Choose the Right Mug

Select a microwave-safe mug that holds at least 12 ounces. This gives the batter enough room to rise while cooking.

Step 2: Mix the Batter

Add the peanut butter, egg, and yogurt directly to the mug.

Using a fork or small whisk, stir until the mixture becomes completely smooth with no streaks remaining.

Step 3: Microwave

Microwave on High for 60 to 90 seconds.

Start checking after 60 seconds. The cake is ready when the center is just set but still soft and moist.

Avoid overcooking, as it can become dry.

Step 4: Cool Slightly

Let the mug cake rest for about one minute before eating.

Enjoy it straight from the mug or gently loosen it with a spoon and transfer it to a dessert plate.

Tips for the Perfect Mug Cake

  • Use smooth peanut butter for the fluffiest texture.

  • Natural peanut butter works but should be stirred well before measuring.

  • Every microwave is different, so begin checking after one minute.

  • Slightly undercooking produces the softest, most tender cake.

  • Add a few chocolate chips before microwaving for a gooey chocolate center.

Delicious Variations

Storage

Frequently Asked Questions

Can I make this mug cake without yogurt?
