Make this incredibly moist and fudgy chocolate mug cake in your microwave in under two minutes. It is the perfect single-serving dessert for late-night sweet cravings with minimal cleanup.

Ingredients

Scale
  • 4 Tablespoons all-purpose flour
  • 4 Tablespoons granulated sugar
  • 2 Tablespoons unsweetened cocoa powder
  • 1/4 teaspoon baking powder
  • Pinch of salt
  • 3 Tablespoons milk (any kind)
  • 1 Tablespoon vegetable oil
  • 1/4 teaspoon vanilla extract
  • 1 Tablespoon chocolate chips (optional, for extra fudginess)

Instructions

  1. Lightly grease the inside of a standard 10-12 ounce microwave-safe mug.
  2. In the mug, whisk together the flour, sugar, cocoa powder, baking powder, and salt until no lumps remain.
  3. Add the milk, vegetable oil, and vanilla extract to the dry ingredients. Stir well until the batter is smooth. Do not overmix.
  4. If using, stir in the chocolate chips, or press a few on top of the batter.
  5. Place the mug in the microwave. Cook on high power for 60 to 90 seconds. Cooking time varies by microwave wattage; start with 60 seconds and add 10-second increments if needed. The cake should look set on top but still slightly soft in the center for a fudgy texture.
  6. Let the mug cake cool for at least one minute before eating directly from the mug.

Notes

  • For a lava cake effect, press one square of dark chocolate into the center of the batter before microwaving.
  • If your microwave is high wattage (over 1000W), start checking at 50 seconds to prevent the cake from becoming dry.
  • Serve warm with a scoop of vanilla ice cream or a dusting of powdered sugar.
