Sometimes you just need enough dessert to satisfy a sweet tooth.  I know my family likes to have dessert and this single-serving dessert is perfect to satisfy that sweet tooth!  This one is made in the microwave and is delicious hot or cold.  It's like a warm, peanut butter cookie, who can resist that?

I introduced mug cakes in 2012 and they went crazy!  It's my crazy easy 3-2-1 Mug Cake that started this whole crazy journey!  In this mug cake, I use brown sugar from Dixie Crystals.  Dixie Crystals Light Brown Sugar is non-GMO pure cane sugar. It smells fantastic, with a light molasses flavor that brings this cake to its highest potential.  I also trust Dixie Crystals to provide a quality product for my baking.  They've been around for over 100 years!

Peanut Butter Mug Cake

The perfect, individualize sized treat!


  • 3 tablespoons peanut butter
  • 1 egg
  • 2 teaspoons brown sugar
  • a few chocolate chips


  1. Prepare a microwave-safe cup with cooking spray.
  2. Add all ingredients to the cup and beat with a fork until all are combined.  Add 1 tablespoon of milk if the batter seems too thick.  Different peanut butter has a different consistency.
  3. Microwave for one minute 30 seconds or until the top looks dry and the cake has "puffed" up.
