Make this single serving chocolate cake in a mug using your microwave. This recipe delivers a gooey, moist dessert in under five minutes, solving your instant dessert cravings.

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
  • 1 Tablespoon vegetable oil
  • 1/4 teaspoon vanilla extract
  • 1 Tablespoon chocolate chips (optional, for extra gooeyness)

Instructions

  1. Find a standard, microwave-safe mug (about 10-12 ounces).
  2. Add the flour, sugar, cocoa powder, baking powder, and salt directly into the mug. Use a small fork to mix these dry ingredients well until no lumps remain.
  3. Add the milk, vegetable oil, and vanilla extract to the dry mixture in the mug.
  4. Stir everything together until just combined. Do not overmix; a few small lumps are acceptable.
  5. If using, stir in the chocolate chips, or drop them on top of the batter.
  6. Place the mug in the microwave. Cook on high power for 60 to 90 seconds. Cooking time varies based on microwave wattage. Start checking at 60 seconds.
  7. The cake is done when the top looks set but still slightly moist. Avoid overcooking to keep it gooey.
  8. Let the mug cake cool for one minute before eating directly from the mug.

Notes

  • For a richer flavor, substitute the vegetable oil with melted butter.
  • If you want a lava effect, push a small square of chocolate into the center of the batter before microwaving.
  • This recipe makes one serving, perfect for a dessert for one.
