Ingredients

Scale
  • 4 tablespoons (about 30 grams) all-purpose flour
  • 2 tablespoons granulated sugar
  • 1 tablespoon unsweetened cocoa powder
  • 1/4 teaspoon baking powder
  • A pinch of salt
  • 3 tablespoons (45 ml) milk (dairy or almond milk)
  • 2 tablespoons (30 ml) vegetable oil (or melted coconut oil)
  • 1/2 teaspoon vanilla extract
  • 810 mini marshmallows
  • 1 tablespoon chocolate chips (optional)
  • 1 tablespoon graham cracker crumbs

Instructions

  1. In a microwave-safe mug, add 4 tablespoons (30 g) all-purpose flour, 2 tablespoons sugar, 1 tablespoon unsweetened cocoa powder, 1/4 teaspoon baking powder, and a pinch of salt. Stir with a fork or small whisk to combine evenly.
  2. Pour in 3 tablespoons (45 ml) milk, 2 tablespoons (30 ml) vegetable oil, and 1/2 teaspoon vanilla extract. Mix thoroughly until smooth and glossy.
  3. Stir in 1 tablespoon chocolate chips and 1 tablespoon graham cracker crumbs gently.
  4. Place 8-10 mini marshmallows evenly on top of the batter without mixing them in.
  5. Microwave on high for 60 seconds initially. Check doneness by pressing the top; it should spring back but remain soft. If still wet, microwave in 10-second bursts up to 90 seconds max.
  6. Let the mug cake sit for 2 minutes to cool slightly before serving.

Notes

Use a larger mug to prevent overflow and avoid filling more than halfway. Adjust microwave time based on wattage. For dairy-free, use plant-based milk and vegan marshmallows. Clean melted marshmallow drips promptly to avoid mess.
