  • Total Time: 6 minutes
  • Yield: 1 serving 1x
  • Category: Dessert
  • Method: Microwave
  • Cuisine: American


  • 3 tablespoons all-purpose flour
  • 2 +1/2 tablespoons brown sugar
  • 2 tablespoons unsweetened cocoa powder
  • pinch of salt
  • 3 tablespoons canola or vegetable oil
  • 3 tablespoons water
  • splash of vanilla extract
  • 1 or 2 tablespoons chocolate chips
  • Vanilla bean ice cream – optional but it makes it really good πŸ™‚


  1. In a microwave-safe mug combine all the dry ingredients – flour, brown sugar, cocoa powder and salt. Using a fork stir well and smash out any lumps.
  2. Next, add in the remaining ingredients – oil, water, and vanilla extract. Mix well to combine. Then stir in half the chocolate chips, top the cake with the remaining chips.
  3. Place in the microwave, on a paper towel or paper plate (just in case it overflows) and microwave on high for 1 min. Check with a toothpick for doneness. If undercooked, microwave for another 15-30 seconds.
  4. Be careful! The cake will be HOT! Allow to cool for a few minutes before eating. Top with ice cream and enjoy!


  • I found the best-sized mug is right around 8 ounces. The cake rises but still leaves room for the ice cream. Feel free to use any sized mug you’d like just know if it’s a large mug, it won’t rise to the top. πŸ™‚
  • Doubling the recipe – I’ve tried this and the only change is the microwave time. I had to cook for 2 minutes for the cake to cook through.
