You need a sweet treat right now, and we have the perfect solution! This fudgy chocolate mug cake is a single-serve dessert you can mix and microwave in under two minutes. It is the ultimate quick dessert in a mug for late-night cravings.

Ingredients

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

Instructions

  1. Find a standard, microwave-safe mug (about 10-12 oz size).
  2. Add the dry ingredients to the mug: flour, sugar, cocoa powder, baking powder, and salt. Use a small fork to mix these thoroughly until no clumps remain.
  3. Add the wet ingredients to the mug: milk, vegetable oil, and vanilla extract.
  4. Mix everything together in the mug until just combined. Do not overmix; a few small lumps are fine.
  5. Stir in the chocolate chips, if using.
  6. Place the mug in the microwave. Cook on high power for 60 to 90 seconds. Start with 60 seconds and check the center. If it still looks very wet, microwave in 10-second intervals until the top looks set but the center is still slightly soft for a fudgy texture.
  7. Let the mug cake cool for one minute before eating. Top with ice cream or powdered sugar if you like.

Notes

  • For a richer flavor, substitute the vegetable oil with 1 tablespoon of melted butter.
  • If you want a healthier mug cake option, replace the sugar with a sugar substitute like erythritol, adjusting to taste.
  • This recipe makes one perfect single-serve cake, which helps with portion control dessert goals.
