A simple, fast, and satisfying single-serve mug brownie that delivers rich, fudgy chocolate flavor in under 15 minutes, perfect for solo treats or quick dessert cravings.

Ingredients

Scale
  • 1/4 cup (30g) all-purpose flour (or gluten-free flour blend for gluten-free version)
  • 1/4 cup (50g) granulated sugar
  • 2 tablespoons (10g) unsweetened cocoa powder
  • A pinch of salt
  • 1/8 teaspoon baking powder
  • 2 tablespoons (30ml) vegetable oil (or melted coconut oil for mild coconut flavor)
  • 3 tablespoons (45ml) water (or almond milk for creaminess)
  • 1/4 teaspoon vanilla extract (optional)
  • Optional mix-ins: chocolate chips, chopped nuts, or a spoonful of peanut butter

Instructions

  1. In a microwave-safe mug, combine 1/4 cup all-purpose flour, 1/4 cup sugar, 2 tablespoons cocoa powder, a pinch of salt, and 1/8 teaspoon baking powder. Stir until evenly mixed with no clumps, about 1 minute.
  2. Add 2 tablespoons vegetable oil, 3 tablespoons water, and 1/4 teaspoon vanilla extract. Stir thoroughly until the batter is smooth and glossy, about 1-2 minutes. The texture should be thick but pourable.
  3. Fold in optional mix-ins like chocolate chips or nuts if desired.
  4. Microwave the mug on high for 70-90 seconds. Start with 70 seconds and check; the brownie should be set on top but moist and fudgy inside. Avoid overcooking to prevent rubbery texture.
  5. Let the mug brownie cool for 2 minutes before eating to allow it to finish cooking and cool slightly.

Notes

If microwave wattage varies, adjust cooking time accordingly. Stop halfway and rotate mug for even cooking. Avoid cooking longer than 90 seconds to prevent dryness. Can be baked in oven at 350°F (175°C) for 12-15 minutes in a ramekin if no microwave is available. Optional mix-ins like nuts or peanut butter add texture and flavor. Use fresh cocoa powder for best taste. Pinch of salt enhances chocolate flavor.
