This Hot Chocolate Mug Cake recipe uses just a few simple ingredients and cooks in a mug right in the microwave. One of the ingredients... Hot Cocoa Mix! Hot chocolate in cake form is a fun single serving dessert. Don't forget the warm, gooey marshmallows on top.


  • 3 tablespoons All Purpose Flour
  • 2 tablespoons Hot Cocoa Mix
  • 1 tablespoon Granulated White Sugar
  • 1/4 teaspoon Baking Powder
  • 2 tablespoons Milk
  • 1 tablespoon Canola Oil
  • 5 Mini Marshmallows, optional


  1. Mix Batter. Add all ingredients, except for mini marshmallows, to a microwave-safe mug. Use a fork to mix up until the batter is smooth.
  2. Optional: If desired, you can top with the marshmallows before baking - they will completely melt into the cake. Or, you can top at the end. See post for picture differences.
  3. Microwave. Microwave cake for 45 seconds to 1 minute, until the cake is just set and cooked. Top with marshmallows. Cake is best eaten warm soon after making.


Hot Cocoa Mix - Make sure to use a mix that can be mixed with water, not one that must be mixed with milk. Use your favorite mix and have fun experimenting with different kinds.

Mug - Any standard size (8 ounces or larger) coffee mug works! The cake will puff up slightly and rise as it bakes. The most important piece is to use a mug that is microwave safe!
