Ingredients

  • 2 tablespoons - all-purpose flour
  • 1 tbsp - granulated sugar
  • 25 tablespoons - good quality hot chocolate mix
  • ¼ tsp - baking powder
  • 1 pinch - Kosher salt
  • 3 tablespoons - whole milk
  • 1 tbsp - neutral oil
  • ⅛ tsp - pure vanilla extract
  • mini marshmallows

Instructions

  1. Grease a mug with neutral oil or baking spray. Then, whisk the flour, sugar, hot chocolate mix, baking powder, and Kosher salt in the mug.
  2. Make a well in the center of the dry ingredients. Add the milk, oil, and vanilla extract. Whisk just until the batter comes together and there are no more streaks of flour. Use a rubber spatula to make sure you get all the dry ingredients at the bottom!
  3. Microwave the cake for about 1 ½ minutes, or until an inserted toothpick comes out clean. The top should still be a little shiny. Don't overcook the cake!
  4. If using, drizzle some marshmallow cream on top, or add a sprinkle of mini marshmallows. Use a kitchen torch or the broiler in your oven to toast the marshmallow. Or, microwave the cake for 10-15 more seconds, just until the marshmallow is soft and fluffy. Let it cool for a few minutes and enjoy!
