A quick and comforting fudgy brownie made in a mug in just 3 minutes, perfect for stress relief and satisfying chocolate cravings without the fuss of baking a whole pan.

Ingredients

Scale
  • 4 tablespoons (30 grams) all-purpose flour
  • 2 tablespoons (10 grams) unsweetened cocoa powder
  • 3 tablespoons (38 grams) sugar
  • 1/4 teaspoon (1 gram) baking powder
  • a pinch of salt
  • 3 tablespoons (45 ml) milk (whole or 2%, or dairy-free alternatives like almond or oat milk)
  • 2 tablespoons (30 ml) vegetable oil (or melted coconut oil)
  • 1/4 teaspoon (1.25 ml) vanilla extract
  • Optional: a pinch of instant espresso powder
  • Optional: mini chocolate chips or a teaspoon of peanut butter

Instructions

  1. In a microwave-safe mug, combine 4 tablespoons of all-purpose flour, 2 tablespoons cocoa powder, 3 tablespoons sugar, 1/4 teaspoon baking powder, and a pinch of salt. Stir gently until evenly mixed, about 30 seconds. Avoid over-mixing.
  2. Add 3 tablespoons milk, 2 tablespoons vegetable oil, and 1/4 teaspoon vanilla extract to the mug. Stir gently until smooth with no dry spots. If batter is too dry, add about 1 teaspoon more milk.
  3. If desired, sprinkle a pinch of instant espresso powder or fold in mini chocolate chips or peanut butter. Stir gently.
  4. Microwave on high for 70 to 90 seconds. Start with 70 seconds and check; the top should be set but the center moist and gooey. Avoid overcooking.
  5. Let the brownie rest for about 1 minute before eating to finish cooking gently and cool slightly.

Notes

Avoid over-mixing the batter to keep the brownie tender. Start microwaving at 70 seconds and adjust time based on your microwave’s power. Let the brownie rest for 1 minute after microwaving to finish cooking and cool slightly. Optional mix-ins like espresso powder, chocolate chips, or peanut butter add flavor and texture. Use a ceramic mug with thick walls for even cooking. For gluten-free, substitute flour with a 1:1 gluten-free blend. For keto, use almond flour, erythritol, and unsweetened almond milk.
