Make the best single serving chocolate cake in minutes. This microwave mug cake recipe creates a rich, gooey dessert that avoids the spongy texture of typical microwave cakes.

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 gooeyness)

Instructions

  1. Choose a microwave-safe mug that holds at least 10-12 ounces.
  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 place them on top of the batter.
  5. Place the mug in the microwave. Cook on high power for 60 to 90 seconds. Start checking at 60 seconds. The cake is done when the top looks set but the center is still slightly soft or gooey.
  6. Let the mug cake cool in the mug for one minute before eating directly from the mug.

Notes

  • For a richer flavor, use dark cocoa powder.
  • If your microwave is very powerful, you may need to reduce the cooking time to 50 seconds to prevent drying out.
  • Serve immediately with a scoop of vanilla ice cream or a dusting of powdered sugar.
