Ingredients

Scale

Dry Ingredients

  • 2 1/2 tablespoons Dutch process cocoa powder
  • 1 1/2 tablespoons all-purpose flour
  • 2 tablespoons granulated white sugar

Wet Ingredients

  • 2 tablespoons canola, vegetable, or olive oil
  • 2 tablespoons water

Chocolate

  • 1 1/2 tablespoons chopped dark chocolate

Instructions

  1. Combine dry ingredients: In an 8 oz microwave-safe mug, add the cocoa powder, flour, and sugar. Whisk together thoroughly with a mini whisk or fork until well mixed and there are no lumps.
  2. Add wet ingredients: Pour the oil and water into the mug with the dry ingredients. Whisk briskly to form a smooth batter, ensuring any lumps of cocoa or flour are fully broken up.
  3. Mix in chocolate: Stir half of the chopped dark chocolate into the batter to distribute rich chocolate pieces throughout. Then sprinkle the remaining chopped chocolate evenly on top of the batter.
  4. Microwave cooking: Microwave the mug brownie on full power for about 40 seconds. Cooking times may vary based on your microwave wattage. The surface should no longer be wet but might still be slightly moist, indicating a fudgy texture.
  5. Cool and serve: Let the brownie cool for a few minutes directly in the mug. Enjoy it warm with a spoon straight from the mug for the ultimate quick chocolate treat.

Notes

  • Microwave times may vary; start with 40 seconds and add additional time in 5-second increments if needed.
  • Use a mug that holds at least 8 ounces to prevent batter overflow.
  • For a richer brownie, use dark or bittersweet chocolate.
  • The brownie will be fudgiest when slightly undercooked and moist on top.
  • Optional: Add a pinch of salt to enhance the chocolate flavor.
