Make this rich, fudgy chocolate mug cake in under five minutes using only your microwave. It is the perfect single-serve dessert for late-night cravings and requires 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)

Instructions

  1. Find a standard, microwave-safe mug (about 10-12 ounces).
  2. Add the dry ingredients to the mug: flour, sugar, cocoa powder, baking powder, and salt. Use a small fork to mix these thoroughly right in the mug until no clumps remain.
  3. Add the wet ingredients to the dry mixture: milk, vegetable oil, and vanilla extract.
  4. Stir everything together until just combined. Do not overmix; a few small lumps are fine.
  5. If using, stir in the chocolate chips or drop them on top.
  6. Place the mug in the microwave. Cook on high power for 60 to 90 seconds. Cooking time varies based on microwave wattage. Start with 60 seconds.
  7. Check the cake; it should look set on top but still slightly moist in the center for a fudgy texture. If it looks wet, microwave in 10-second increments until done.
  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 fluffier cake, use slightly less oil or add one extra teaspoon of milk.
  • This recipe is a great base; try adding a pinch of cinnamon or instant coffee powder for depth.
  • This is a perfect portion control dessert for satisfying sweet tooth desires instantly.
