Equipment

  • Microwave-safe mug or ramekin

Ingredients
  

  • 15 grams all purpose flour (2 Tablespoons)
  • 12 grams granulated sugar (1 Tablespoon)
  • 25 grams good quality hot chocolate mix (2 Tablespoons)
  • ¼ teaspoon baking powder
  • Pinch of Kosher salt
  • 45 milliliters whole milk (3 Tablespoons)
  • 15 milliliters neutral oil (1 Tablespoon)
  • teaspoon pure vanilla extract
  • Marshmallow cream or mini marshmallows, for topping, optional

Instructions
 

  • 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.
  • 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!
  • 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!
  • 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!

Notes

Use a good quality hot chocolate mix. The better the mix, the better the cake!
It's super important to not overcook the cake! If you microwave it for too long, it'll come out dry or gummy. Microwave the cake just until an inserted toothpick comes out clean.
Please keep in mind that mug cakes are not the same as regular cake. Yes, this recipe is very good, but it's not going to be the same as a gourmet, from-scratch cake. :)
