Ingredients

Scale

Dry Ingredients

  • 2 tbsp cocoa powder
  • 1/4 cup all-purpose flour
  • 1/2 tsp baking soda
  • Pinch of salt
  • 3 tbsp brown sugar

Wet Ingredients

  • 3 tbsp melted butter
  • 3 tbsp milk
  • 1/2 tsp vinegar

Add-ins

  • 1 tbsp chocolate chips

To Serve

  • Vanilla ice cream (optional)

Instructions

  1. Mix Dry Ingredients: In the microwave-safe mug you will use for baking, combine the cocoa powder, flour, baking soda, salt, and brown sugar. Stir well to evenly distribute all dry ingredients.
  2. Add Wet Ingredients: Pour in the melted butter, milk, and vinegar to the dry ingredients in the mug. Mix thoroughly until the batter is smooth and fully combined.
  3. Add Chocolate Chips: Stir in the chocolate chips evenly into the batter to add extra gooey chocolate pockets in your brownie.
  4. Microwave Bake: Place the mug in the microwave and cook on the regular heating setting for 1 minute. Carefully check the brownie’s doneness; it should be slightly underbaked inside.
  5. Continue Baking: If needed, continue microwaving in 30-second intervals up to two more times (totalling about 2 minutes) until the brownie is just cooked but still moist and fudgy.
  6. Serve: It’s best to serve the brownie hot and slightly underbaked for a soft center. Top with vanilla ice cream or whipped cream to elevate the dessert.

Notes

  • Microwave wattages vary. Adjust cooking time accordingly to avoid overcooking.
  • Underbaking slightly gives the best fudgy texture for the mug cake.
  • Serve immediately for the best taste and texture as microwaved brownies can become dense when cooled.
  • You can substitute brown sugar with white sugar or coconut sugar.
  • For a dairy-free option, use a plant-based milk and vegan butter.
