Peanut Butter Chocolate Chip Mug Cake


Creamy, fluffy, eggless peanut butter cake mixed with melty chocolate chips. This single serving mug cake is ready in about 5 minutes.

It’s been a while since I made a mug cake. But it’s really perfect right now. Because even though I’m trying to eat healthy, I still need a little treat. And this single serving cake means I won’t be tempted to eat an entire full-sized cake or a dozen cookies.


The peanut butter mug cake is one of my favorites. I just adjusted my recipe a little to add melty chocolate. I used chocolate chunks rather than standard chocolate chips since the chunks are bigger. I’m so happy Nestle came out with chocolate chunks so I don’t have to buy them at specialty baking stores.

This cake is best eaten warm, while the chocolate is still melty and gooey. Because this cake is eggless, the crumb is a little loose. It’s best eaten in the mug as it won’t hold up well if you try to remove it from the mug. So I recommend you just grab a spoon and dig in.

Peanut Butter Chocolate Chip Mug Cake

Single serving creamy, fluffy, eggless peanut butter cake mixed with gooey melted chocolate chips. Cooks in the microwave and is ready in minutes.

Ingredients:

  • 4 tbsp all-purpose flour
  • 1/4 tsp baking powder
  • 1 tbsp granulated sugar
  • 1/4 cup fat-free milk
  • 3 tbsp creamy peanut butter
  • 3 tbsp semi-sweet chocolate chunks or chocolate chips

Directions:

  1. In a microwave safe mug, add all ingredients except chocolate. Using a small whisk, mix vigorously until batter is smooth and no flour chunks remain.
  2. Stir 1 tbsp of chocolate chips into the cake batter. Add another 1 tbsp concentrated in the center/middle of the batter (so that when you dig into the center of your cake when it's finished, it has a concentrated amount of chocolate). Sprinkle remaining 1 tbsp on top.
  3. Cook in the microwave at full power for about 1 minute. If cake batter is still gooey, cook for an additional 15 seconds. Allow cake to cool a few minutes before eating. Cake is best eaten warm.
  • It is best to eat the cake directly from the mug and avoid removing it from the mug to eat it as the crumb is looser than a traditional cake.
  • If you choose to omit the chocolate chips, you may need to add more sugar to the batter.
