Chocolate Peanut Butter Lava Mug Cake

You won't believe this ooey-gooey cake was made in the microwave in 90 seconds. You don't need to add an egg to it, and that's actually the key to why this dessert is extra moist and delicious. A regular cake usually has one to two eggs, so why add one to a little mug cake? This is an excellent time and ingredient saver for those times when you've got a sweet tooth.


I used a clear Pyrex cup so it's easier to see. Use any cylindrical mug with straight sides for even cake rise.

Prep Time: 3 minutes

Cook Time: 1 minute 30 seconds

  1. In your microwave safe mug, melt the butter in the microwave for 30 seconds, then allow to cool while you prepare the rest of the mix.
  2. In a small bowl, thoroughly whisk together flour, hot cocoa mix, and baking powder.
  3. Pour milk, butter, and vanilla into the dry mixture.
  4. Stir until it's completely smooth.
  5. Pour the batter into the mug.
  6. Combine peanut butter and chocolate chips in the small bowl, stir well.
  7. Scoop into the center of the batter in the mug.
  8. Seal the top by spooning batter from the side over the peanut butter and chocolate chips.
  9. Microwave on high for about 90 seconds.
  10. Allow to cool a couple minutes before digging in.
