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)

Optional Add-ins

  • 1 tablespoon chocolate chips or chopped chocolate

Instructions

  1. Combine dry ingredients: In a microwave-safe mug of about 10–12 oz capacity, mix together the flour, sugar, cocoa powder, and a pinch of salt thoroughly using a fork or small whisk to ensure even distribution.
  2. Add wet ingredients: Pour in the vegetable oil and water, and vanilla extract if using, into the dry mix. Stir well until the batter is smooth and free of lumps, creating a consistent mixture.
  3. Incorporate chocolate chips: Fold in chocolate chips or chopped chocolate gently into the batter to add extra gooeyness and chocolate flavor to your brownie.
  4. Microwave cooking: Microwave the mug on high power for 60 to 90 seconds. Watch carefully – the surface should look set but the center remain slightly gooey. Avoid overcooking as it will dry out the brownie.
  5. Cool and serve: Let the brownie rest for 1–2 minutes after microwaving to finish setting and to cool slightly. Enjoy directly from the mug or enhance by topping with whipped cream, ice cream, or chocolate syrup.

Notes

  • Microwave power varies; adjust cooking time accordingly to prevent overcooking.
  • Use a microwave-safe mug with at least 10 oz capacity to avoid overflow during cooking.
  • Vanilla extract is optional but adds a nice depth of flavor.
  • For a richer taste, substitute vegetable oil with melted butter.
  • Add toppings like nuts or caramel sauce for extra texture and flavor variety.
  • This recipe is egg-free and dairy-free, making it less perishable and suitable for dorm living.
