  • Mug


  • 3 tablespoons unsweetened cocoa powder
  • 3 tablespoons all-purpose flour
  • 3 tablespoons granulated sugar
  • generous pinch of salt
  • 3 tablespoons milk
  • tablespoons vegetable oil
  • ¼ teaspoon vanilla extract
  • 2 tablespoons chocolate chips plus more for sprinkling
  • ice cream to serve


  • Combine cocoa powder, flour, sugar, and salt in a 10- to 12-ounce microwave-safe coffee mug. Using a fork, stir until well combined. Add the milk, oil, and vanilla. Stir just until the dry ingredients are almost combined. Add the chocolate chips, and stir until well combined. Sprinkle a few more chocolate chips on top, if desired.
  • Place the mug in the microwave and microwave on high power for 1 minute. The brownie should have risen and still appear moist in spots on the top. Continue cooking in 10-second intervals if the batter still looks raw. Let the brownie cool for a few minutes before serving with ice cream.


  • Make sure to measure your flour correctly. If you add too much flour to the recipe, you will have a less dense and fudgy mug brownie. I highly recommend using a scale to measure your flour. However, if you don’t have a scale, be sure to fluff your flour with a spoon and then spoon it into your cups before leveling it off with a knife. This method is the best way to measure flour without overpacking the measuring cup.
  • Use real vanilla extract for the best flavor.
  • A shorter, wider mug is ideal as it allows for more even cooking. I recommend a heavy ceramic mug with no metal.
  • Avoid overcooking your brownie in a cup, as you will end up with a dry brownie.
  • Do not overmix the batter, as it will lead to a tough brownie.
  • The center will continue to bake and set after you remove the mug from the microwave, so don’t worry if they seem a bit too soft and fudgy.
