Ingredients
  

  • 4 tablespoons all-purpose flour
  • 2 tablespoons unsweetened cocoa powder Dutch-processed works best
  • 3 tablespoons granulated sugar
  • ¼ teaspoon baking powder
  • Pinch of salt
  • 5 tablespoons milk any kind works
  • 2 tablespoons vegetable oil or melted butter
  • ¼ teaspoon vanilla extract
  • 1 tablespoon chocolate chips optional, but highly recommended

Instructions
 

  • Prepare your mug by ensuring it’s microwave-safe and at least 12 ounces in capacity to prevent overflow.
  • Add all dry ingredients (flour, cocoa powder, sugar, baking powder, and salt) to your mug and whisk with a fork until well combined and no cocoa lumps remain.
  • Pour in the wet ingredients (milk, oil, and vanilla) and stir until you have a smooth batter, making sure to scrape the bottom and sides of the mug to incorporate all the dry ingredients.
  • Sprinkle chocolate chips on top of the batter if using—they’ll melt into pockets of gooey goodness.
  • Microwave on high for 70-90 seconds, watching carefully. The cake is done when it rises to the top of the mug and looks set but still slightly moist on top. For a molten center, aim for 70 seconds.
  • Let the cake rest for 1 minute before enjoying—it will be extremely hot and continues cooking slightly as it stands.

Notes

  • For a richer flavor, try brown sugar instead of white.
  • The quality of your cocoa powder dramatically affects the final taste—use the best you can.
  • Microwave power varies significantly, so start with 70 seconds and add more time if needed.
  • For a more “adult” version, add a splash of coffee liqueur or espresso.
  • This recipe can be prepared ahead of time (dry and wet ingredients separately) and mixed/cooked when ready to eat.
