Ingredients
  

Dry Ingredients
  • 3 tablespoons unsweetened cocoa powder natural or Dutch-processed
  • 3 tablespoons all-purpose flour measured correctly
  • 3 tablespoons granulated sugar
  • 1 pinch salt generous pinch
Wet Ingredients
  • 3 tablespoons milk any type
  • 2½ tablespoons vegetable oil
  • ¼ teaspoon vanilla extract use real vanilla
Mix-ins
  • 2 tablespoons chocolate chips plus extra for topping
  • 1 scoop vanilla ice cream for serving

Equipment

  • 10-12 ounce microwave-safe ceramic mug
  • Fork for mixing
  • Microwave

Method
 

  1. Mix dry ingredients: Combine cocoa powder, flour, sugar, and salt in a 10-12 ounce microwave-safe ceramic mug. Use a fork to stir until well combined.
  2. Add wet ingredients: Pour in milk, vegetable oil, and vanilla extract.
  3. Combine carefully: Stir just until dry ingredients are almost combined. Do not overmix to avoid tough texture.
  4. Add chocolate chips: Fold in 2 tablespoons chocolate chips and sprinkle extra on top if desired.
  5. Microwave: Place mug in microwave and cook on high power for 1 minute. The brownie should have risen and still appear moist in spots on top.
  6. Check doneness: If batter still looks raw, continue cooking in 10-second intervals until set.
  7. Cool and serve: Let brownie rest for 2-3 minutes to set properly, then serve with vanilla ice cream.

Notes

Flour measurement: Fluff flour with a spoon, then level with a knife to avoid dense brownies. Use a kitchen scale for best results.
Mug selection: Choose a shorter, wider ceramic mug for even cooking. Avoid metal mugs.
Cooking tips: The center continues cooking after microwaving, so slight undercooking is better than overdrying. Don't overmix the batter.
Variations: Add peanut butter swirl, Nutella, jam, or chopped nuts for variety.
