  • 2 tablespoons (30 grams) unsalted butter , melted and slightly cooled
  • 3 tablespoons (38 grams) granulated sugar
  • 1 tablespoon (12 grams) brown sugar (light or dark)
  • 2 tablespoons (30 ml) water , room temperature
  • ½ teaspoon pure vanilla extract
  • ¼ cup (32 grams) all-purpose flour , spooned & leveled
  • 2 tablespoons (10 grams) natural unsweetened cocoa powder , sifted
  • Tiny pinch of salt
  • 1 tablespoon (15 grams) mini semi-sweet chocolate chips (optional)


  • Grease a mug with nonstick cooking spray.
  • Combine the melted butter, granulated sugar, and brown sugar in a medium-sized mixing bowl and whisk until well combined. Whisk in the water and pure vanilla extract.
  • Add the flour, sifted cocoa powder, and salt and whisk until fully combined and no lumps remain. Stir in the semi-sweet chocolate chips.
  • Pour the batter into the prepared mug and smooth out the top. Sprinkle additional chocolate chips on top if desired.
  • Microwave for 60 to 75 seconds or until the top is just set (I microwave mine for right at 60 seconds).
  • Carefully remove from the microwave and set aside to cool for a few minutes. Top with ice cream or your favorite toppings right before serving.


Storage Instructions: This recipe is best served soon after it's cooked, but can be covered tightly and stored at room temperature for 1 to 2 days. Reheat in the microwave if desired.
Freezing Instructions: Remove the brownie from the mug, wrap it tightly with plastic wrap, and store in the freezer for up to 3 months. Thaw to room temperature and reheat in the microwave for a few seconds.
Brown Sugar: This adds a little more moisture to the brownie to help make it fudgy. If you don't have any on hand, you can replace it with granulated sugar.
Chocolate Chips: Feel free to replace the chocolate chips with another mix-in like peanut butter chips or chopped nuts.
