Ingredients Method

Ingredients
  

  • 1/4 cup all-purpose flour
  • 2 tablespoons hot cocoa mix (regular or dark)
  • 2 teaspoons unsweetened cocoa powder (for extra richness)
  • 2 tablespoons granulated sugar (adjust to taste)
  • 1/4 teaspoon baking powder
  • Pinch of salt
  • 3 tablespoons milk (dairy or non-dairy)
  • 1 tablespoon neutral oil or melted butter
  • 1/2 teaspoon vanilla extract
  • 1 tablespoon chocolate chips (optional but recommended)
  • Mini marshmallows for topping (optional)

Method
 

  1. Choose the right mug: Use a microwave-safe mug that holds at least 12 ounces to prevent overflow.
  2. Mix dry ingredients: Add flour, hot cocoa mix, cocoa powder, sugar, baking powder, and salt to the mug. Whisk with a fork until well combined.
  3. Add wet ingredients: Pour in milk, oil (or melted butter), and vanilla. Stir until the batter is smooth and no dry pockets remain.
  4. Stir in extras: Fold in chocolate chips for melty pockets of goodness. Smooth the top.
  5. Microwave: Cook on high for 60–90 seconds. Start checking at 60 seconds; the cake should look set on top but slightly glossy in the center.
  6. Rest briefly: Let it sit for 1 minute. It continues to set as it cools.
  7. Top and enjoy: Add mini marshmallows or a drizzle of cream. Eat warm right from the mug.
