A quick and easy single-serve mug brownie with a gooey molten chocolate center, perfect for satisfying last-minute dessert cravings with minimal effort and cleanup.

Ingredients

Scale
  • 4 tablespoons (30 g) all-purpose flour
  • 4 tablespoons (50 g) granulated sugar
  • 2 tablespoons (10 g) unsweetened cocoa powder
  • 1/8 teaspoon baking powder
  • Pinch of salt
  • 3 tablespoons (45 ml) milk (any kind, dairy or plant-based)
  • 2 tablespoons (30 ml) vegetable oil
  • 1/4 teaspoon vanilla extract
  • 1 tablespoon (15 g) chocolate chunk or chocolate chips
  • Optional: 1/8 teaspoon espresso powder

Instructions

  1. In your microwave-safe mug, stir together the all-purpose flour, granulated sugar, unsweetened cocoa powder, baking powder, salt, and optional espresso powder until well combined and free of lumps.
  2. Add the milk, vegetable oil, and vanilla extract to the dry ingredients and stir thoroughly until you have a smooth batter with no dry pockets.
  3. Press the chocolate chunk or chips into the center of the batter, slightly burying it so it melts inside during cooking.
  4. Microwave on high for 50-60 seconds. The brownie should be set around the edges but still slightly soft in the center. Adjust cooking time in 10-second increments if needed.
  5. Let the mug brownie cool for 1-2 minutes before eating to allow the molten center to set slightly and avoid burning your tongue.

Notes

Use a ceramic mug about 12 ounces to avoid overflow. Adjust microwave time based on your microwave’s wattage, starting with 50 seconds and adding 10-second bursts if needed. Press the chocolate chunk into the center for a molten core. Overcooking will dry out the brownie. Fresh baking powder improves texture. Optional espresso powder intensifies chocolate flavor without adding coffee taste. Variations include using almond or oat milk and coconut oil for vegan/dairy-free, adding peanut butter, chili powder, or marshmallows for flavor and texture twists. Can be baked in a small ramekin at 350°F for 12-15 minutes if no microwave is available.
