Equipment

  • Microwave-safe mug
  • Fork or small whisk
  • Measuring spoons
  • Microwave

Ingredients
  

  • 4 tablespoons all-purpose flour
  • 2 tablespoons cocoa powder
  • 4 tablespoons granulated sugar
  • 1/8 teaspoon baking powder
  • Pinch of salt
  • 3 tablespoons milk whole milk recommended for richer taste
  • 2 tablespoons vegetable oil or melted butter
  • 1/4 teaspoon vanilla extract
  • 1 tablespoon mini marshmallows optional, for topping
  • 1/8 teaspoon baking soda
  • 1/4 – 1/2 teaspoon coffee or espresso powder optional
  • 1 egg
  • Whipped cream optional, for topping

Instructions
 

  • Prepare the mug: Choose a microwave-safe mug with a capacity of at least 12 oz (for proper rising).
  • Mix the dry ingredients: In the mug, combine the 4 tablespoons of flour, 2 tablespoons cocoa powder, 4 tablespoons sugar, 1/8 teaspoon baking powder, 1/8 teaspoon baking soda, and a pinch of salt. If you’re adding coffee or espresso powder, mix that in as well.
  • Add the wet ingredients: To the dry mixture, add the 3 tablespoons of milk, 2 tablespoons of vegetable oil (or melted butter), 1/4 teaspoon vanilla extract, and 1 egg. Stir well with a fork or whisk until fully combined and smooth.
  • Add marshmallows (optional): If using, sprinkle 1 tablespoon of mini marshmallows on top of the batter.
  • Microwave: Microwave the mug on high for about 1 minute and 15 seconds, checking at the 1-minute mark. The cake should rise and look set, but still soft in the center. If not done, microwave for 15-20 more seconds.
  • Top and serve: Once done, let the cake cool for a minute before adding a dollop of whipped cream (if using) and extra mini marshmallows. Enjoy your hot chocolate mug cake!

Notes

 Microwave wattage: The cooking time may vary depending on your microwave’s wattage. For best results, start with 1 minute and check if the cake is fully cooked by gently poking it with a toothpick. If it comes out clean, it’s done!
 Add-ins: If you like your mug cake extra chocolaty, try adding chocolate chips or chunks to the batter before microwaving.
 Dairy-Free Version: You can easily make this cake dairy-free by swapping the milk for almond or oat milk and using a plant-based oil or butter.
