Ingredients

Scale

Dry Ingredients

  • 1/4 cup (30g) all-purpose flour
  • 1/4 cup (50g) granulated sugar
  • 2 tablespoons (10g) unsweetened cocoa powder
  • A pinch of salt

Wet Ingredients

  • 2 tablespoons (30ml) vegetable oil (or melted butter)
  • 3 tablespoons (45ml) water
  • 1/4 teaspoon vanilla extract (optional)

Add-ins

  • 1 tablespoon chocolate chips or chopped chocolate (optional)

Instructions

  1. Mix Dry Ingredients: In a microwave-safe mug (about 10–12 oz), combine the flour, sugar, cocoa powder, and salt. Stir thoroughly with a fork or small whisk until well mixed.
  2. Add Wet Ingredients: Pour in the vegetable oil, water, and vanilla extract if using. Stir the mixture until you have a smooth, lump-free batter.
  3. Mix in Chocolate Chips: Fold in the chocolate chips or chopped chocolate, if desired, to add an extra gooey texture.
  4. Microwave Cooking: Place the mug in the microwave and cook on high for 60 to 90 seconds. The surface should look set but the center will still be slightly gooey. Avoid overcooking to keep the brownie moist.
  5. Cool and Serve: Let the brownie cool in the mug for 1 to 2 minutes before eating. Enjoy as is or top with whipped cream, ice cream, or chocolate syrup for an extra treat.

Notes

  • Microwave wattages vary, so adjust cooking time as needed—start with 60 seconds and add time in 10-second increments.
  • Do not overcook; the brownie will continue to cook slightly after microwaving.
  • Using vegetable oil keeps the recipe dairy-free, but melted butter can be substituted for a richer flavor.
  • Adding vanilla extract enhances flavor but is optional.
  • The recipe is egg-free, making it suitable for dorms where eggs may not be allowed or available.
  • Cleanup is easy since this is made and served in a single mug.
