Ingredients

  • 3 tablespoons all-purpose flour
  • 3 tablespoons Dutch-process cocoa powder
  • 3 tablespoons brown sugar
  • 1 pinch salt
  • ¼ teaspoon vanilla extract
  • 3 tablespoons milk
  • 3 tablespoons vegetable oil
  • 2 tablespoons chocolate chunks or chips
  • 1 tablespoon beaten egg

Instructions

  1. Step 1: In a 6 to 8-ounce microwave-safe mug, stir together the flour, cocoa powder, brown sugar, and salt until well combined.
  2. Step 2: In a separate bowl, beat one egg thoroughly with a fork or small whisk. Measure out 1 tablespoon of the beaten egg and add it to the mug.
  3. Step 3: Add the vanilla extract, milk, and vegetable oil to the mug. Stir everything together to form a smooth batter.
  4. Step 4: Mix in half of the chocolate chunks into the batter, then sprinkle the remaining chunks on top.
  5. Step 5: Microwave the mug for 1 minute to 1 minute 15 seconds. The brownie is done when the surface looks set and no longer wet.

Tips & Variations

  • Use dark or semi-sweet chocolate chunks for richer flavor, or swap them with nuts for added crunch.
  • Adjust the microwave time slightly depending on your oven’s wattage to avoid overcooking.
  • For a fudgier texture, reduce the flour by 1 tablespoon.

Storage

Brownie in a mug is best enjoyed immediately for the freshest taste and texture. If you have leftovers, cover the mug and refrigerate for up to 24 hours. Reheat briefly in the microwave for about 20-30 seconds before eating.

FAQs

Can I make this brownie without an egg?

Yes, you can substitute the egg with 1 tablespoon of applesauce or yogurt to help bind the ingredients, though the texture may be slightly different.

What type of cocoa powder should I use?

Dutch-process cocoa powder is preferred for a smoother, less acidic flavor, but natural cocoa powder works as well if that’s what you have on hand.
