  • 1/4 cup flour
  • 1/4 cup granulated sugar
  • 2 tablespoons unsweetened cocoa powder
  • 1/2 teaspoon baking powder
  • Pinch of salt
  • 3 tablespoons 11/2oz melted butter
  • 1/4 tsp peppermint extract
  • 3 tablespoons whole milk at room temperature
  • 1 egg at room temperature
  • 1/2 teaspoon vanilla extract
  • 1 ounce Crafters & Co. Peppermint Bark Get it at Hallmark Gold Crown Stores
  • 1 tablespoon water


  • 1/2 ounce Peppermint Bark
  • 1 Tbs Whipped cream


  • In a 2 cup capacity or larger mug, whisk flour, sugar, cocoa powder, baking powder and salt with a fork until combined.
  • Add in the melted butter, peppermint extract, milk, egg and vanilla.
  • Use your fork to whisk until it is well combined, and no flour mixture is stuck to the bottom.
  • Take pieces of peppermint bark and place into the center of the mug, it will sink, so no need to push it down.
  • Dump a tablespoon of water on top of the batter. Do not mix it.
  • Cook in microwave on full power for 1 minute and 20 seconds to 2 minutes, until the cake rises to the top, the edges look set but the center looks just a little bit wet, every microwave is different, so touch the center, it should be a little sticky, but not outright wet.
  • If you want a molten interior, do not over bake. Check at the 1 minute 20 second interval, and add 5-10 seconds at a time until desired doneness is reached.
  • Remove from microwave and let it cool 3-5 minutes, cake will fall, but it will help you to not burn your tongue.
  • Top with additional peppermint bark and whipped cream if desired.


Over cooking it can cause it to have a rubbery texture. It should be just barely set, so watch it carefully, and check often until you figure out the magic number for your specific microwave. The inside should be gooey and runny like a lava cake.
