Ingredients
  

Ingredients
  • 3.5 tbsp all-purpose flour
  • 2.5 tbsp sifted cocoa powder
  • 3.5 tbsp brown sugar
  • 1/8 tsp salt
  • 1/4 tsp baking powder
  • 4 tbsp milk
  • 2 tbsp neutral oil vegetable or canola oil
  • 3/4 tsp vanilla extract
  • 2.5 tbsp optional chocolate chips plus extra to sprinkle on top
  • optional toppings vanilla ice cream, whipped cream, chocolate sauce, or caramel sauce

Equipment

  • Microwave-safe Mug
  • Microwave
  • Whisk or Spoon

Method
 

  1. Step 1: In a microwave-safe mug (at least 12 oz), whisk together the flour, sifted cocoa powder, brown sugar, salt, and baking powder until evenly combined.
  2. Step 2: Add milk, oil, and vanilla extract to the mug. Stir thoroughly until the batter is smooth and thick but pourable.
  3. Step 3: Fold in the chocolate chips, reserving a few to sprinkle on top if desired.
  4. Step 4: Microwave on high for 60 seconds. Check the brownie; edges should be set with a slight jiggle in the center. If too wet, microwave in 5-second bursts until just set.
  5. Step 5: Let the brownie rest for 3–4 minutes to finish cooking and develop a gooey texture.
  6. Step 6: Add your favorite toppings like vanilla ice cream, whipped cream, or sauces. Serve immediately and enjoy warm.

Notes

For dairy-free, use plant-based milk and dairy-free chocolate chips. You can bake in a small oven-safe ramekin at 350°F for 12-15 minutes if no microwave is available. Store leftovers covered in the fridge for up to 2 days and reheat briefly.
