A quick and easy 5-minute recipe for rich, fudgy brownies made in a microwave-safe mug, perfect for solo treats and late-night cravings.

Ingredients

Scale
  • 4 tablespoons all-purpose flour (about 30 grams)
  • 4 tablespoons granulated sugar (50 grams)
  • 2 tablespoons unsweetened cocoa powder (15 grams)
  • Pinch of salt
  • 1/8 teaspoon baking powder
  • 3 tablespoons milk (whole or 2%; can substitute almond or oat milk for dairy-free)
  • 2 tablespoons vegetable oil
  • 1/4 teaspoon vanilla extract
  • Optional mix-ins: chocolate chips, chopped nuts, or a sprinkle of sea salt on top

Instructions

  1. In your mug or a small bowl, combine 4 tablespoons of all-purpose flour, 4 tablespoons of granulated sugar, 2 tablespoons of unsweetened cocoa powder, a pinch of salt, and 1/8 teaspoon baking powder. Stir gently to blend evenly, ensuring no lumps remain.
  2. Add 3 tablespoons of milk, 2 tablespoons of vegetable oil, and 1/4 teaspoon vanilla extract. Stir thoroughly until smooth with no dry spots.
  3. Fold in a tablespoon of chocolate chips or chopped nuts if desired.
  4. Place the mug in the microwave and cook on high for 60 to 70 seconds. The brownie should look set but still slightly gooey in the center. If needed, microwave in 10-second bursts to avoid overcooking.
  5. Let the brownie sit for about 2 minutes to finish setting before enjoying.

Notes

Do not overmix the batter to keep the brownie tender and fudgy. Use fresh cocoa powder for best flavor. Microwave times may vary; start with 60 seconds and adjust as needed. Let the brownie rest after microwaving to set the texture. Optional toppings like sea salt or mini marshmallows add a nice twist. For gluten-free, substitute flour with a 1:1 gluten-free blend.
