  • 1 large microwave safe coffee mug (12 ounces)
  • 4 tablespoon flour or 4 tablespoon Gluten Free All Purpose Flour
  • 4 tablespoon light brown sugar
  • 2 tablespoon butter, melted
  • 1 large egg
  • 2 tablespoon cocoa powder
  • 1/2 teaspoon espresso powder
  • 1/4 teaspoon baking powder
  • Pinch of salt
  • 3 tablespoon milk
  • 1 tablespoon vegetable or coconut oil (melted)
  • 1 teaspoon chocolate extract (can use vanilla)
  • 3 tablespoon chocolate chips
  • *Options: 1-2 tablespoon Peanut Butter Caramel Sauce, warmed
  • 1 tablespoon of additional chocolate chips


  1. Spray a 12 ounce coffee mug with cooking spray.
  2. In a bowl whisk together the brown sugar and melted butter.
  3. Whisk in the egg, milk, oil and extract until smooth and well combined.
  4. Add in the flour, baking powder, cocoa powder, salt and espresso powder.
  5. Whisk just until combined – don’t over whisk as you do not want to aerate this.
  6. Fold in the 3 tablespoon of chocolate chips.
  7. Pour this mixture into the mug (or mugs if you plan on sharing).
  8. Microwave on high for 1 minute and 30 seconds. Mine took about 2 minutes and 15 seconds as it’s a smaller microwave. The cake will be done when it’s puffed and still slightly wet/moist. The max cooking time is 3 minutes.
  9. The cake might look like it is overflowing from mug, but it will settle.


Now what I did for mine is when the gooey brownie cake was done I added the remaining 1 tablespoon of chocolate chips on top and then drizzled the warmed peanut butter caramel sauce over it. I then just swirled the mug around a big and the warm sauce melted the chips on top.
