You need a quick, rich dessert. This recipe delivers the moistest chocolate mug cake you will make, ready in under five minutes using your microwave. It is the perfect single serving cake for satisfying late-night 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 (any kind)
  • 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 thoroughly.
  3. Pour in the milk, vegetable oil, and vanilla extract. Mix everything until just combined. Do not overmix; a few small lumps are acceptable.
  4. If you are using them, stir in the chocolate chips, or drop them onto the top of the batter.
  5. Place the mug in the microwave. Cook on high power for 60 to 90 seconds. Cooking time varies based on your microwave wattage. Start with 60 seconds and check for doneness. The cake should look set on top but still slightly soft in the center for maximum moisture.
  6. Let the mug cake cool in the mug for at least one minute before eating. Top with ice cream or powdered sugar if desired.

Notes

  • For a fudgier texture, reduce the milk by 1/2 teaspoon.
  • If your microwave is low wattage (under 1000W), you may need to cook for up to 120 seconds. Watch carefully to prevent drying out.
  • This recipe makes one dessert for one person. Double the ingredients and use two separate mugs if you need two servings.
