Ingredients

  • 3 tablespoons all-purpose flour
  • 1 tablespoon unsweetened cocoa powder
  • 2 tablespoons granulated sugar
  • 1/4 teaspoon baking powder
  • pinch salt
  • 3 tablespoons milk
  • 1 tablespoon cooking oil
  • 1/4 teaspoon pure vanilla extract
  • 2 teaspoons semi-sweet chocolate chips
  • 1 tablespoon crushed graham crackers
  • 3 marshmellows or to taste

Instructions

  • Grease a 12-ounce (or larger) mug with nonstick cooking spray or butter. Set aside.
  • In a separate mixing bowl, whisk together the flour, unsweetened cocoa powder, granulated sugar, baking powder, and salt until well combined. Add the milk, oil, and pure vanilla extract and continue mixing until fully combined.
  • Pour the batter into the prepared mug and sprinkle the chocolate chips on top.
  • Microwave and microwave for 60 to 90 seconds, the center of the cake should be just set. In my microwave (1100 watts) it takes about 75 seconds.
  • Meanwhile, set the oven to broil. Add large marshmallows to a baking pan. Watch carefully and let broil for 5 to 7 seconds (or untiled nicely browned). Using a spatula, flip the marshmallows over and cook for another 1 to 2 seconds.
  • Carefully remove from the mug from the microwave. Top with roasted marshmallows, crushed graham crackers and chocolate bar pieces (or additional chocolate chips. Let cool slightly and enjoy!

Notes

Adding Marshmallows to the Mug Cake without Roasting

Microwave the mug cake about 50 seconds. Add the marshmallows and microwave for an additional 20 to 30 seconds.

How to Roast Marshmallows in the Oven

Set the oven to broil and raise the rack to near the top. Place marshmallows on a baking pan. Don't leave the oven, and watch carefully as the marshmallows roast very quickly. It should take seconds.
With a spatula, flip the marshmallows over and broil for another few seconds. Remove from the oven promptly.
