Description

This fudgy mug brownie is a quick and easy single-serving dessert cooked in the microwave. Made with cocoa powder, flour, sugar, oil, water, and chocolate chunks, it delivers a rich, moist, and chocolatey treat perfect for satisfying your sweet tooth in just minutes.


Ingredients

Scale

Dry Ingredients

  • 2 1/2 tbsp dutch process cocoa powder
  • 1 1/2 tbsp all purpose flour
  • 2 tbsp granulated white sugar

Wet Ingredients

  • 2 tbsp oil (canola, vegetable or olive oil)
  • 2 tbsp water

Chocolate

  • 1 1/2 tbsp chopped dark chocolate


Instructions

  1. Combine Dry Ingredients: In an 8 oz microwave-safe mug, add the cocoa powder, flour, and sugar. Whisk together with a mini whisk until evenly mixed.
  2. Add Wet Ingredients: Add the oil and water to the mug. Whisk briskly until the batter is smooth, making sure to break up any lumps of cocoa or flour for an even texture.
  3. Add Chocolate Chunks: Stir half of the chopped dark chocolate into the batter briefly. Then sprinkle the remaining chocolate evenly on top of the batter.
  4. Microwave Cooking: Cook the mug brownie on full power in the microwave for about 40 seconds. (For a 1000 watt microwave; adjust time or power if your microwave differs.) The top should no longer be wet but may still be slightly moist.
  5. Cool and Serve: Allow the brownie to cool in the mug for a few minutes before eating. It is best enjoyed warm and can be eaten directly from the mug with a spoon.

Notes

  • The single serving size is small and the brownie will rise about two-thirds of the way in an 8 oz mug.
  • The texture is loose and fudgy without an egg, so it should be eaten with a spoon directly in the mug rather than removed in one piece.
  • For a firmer texture, you may substitute 1 tbsp of water with 1 tbsp of whisked egg, though the egg is omitted here for simplicity.
  • The brownie is at its fudgiest and best just after cooking while warm. Once cooled, it loses some of its softness and crumbs become looser.
  • Doubling the recipe in one mug is not recommended as the single serving cooks more evenly; make separate single-serving brownies instead.
