🛒 Ingredients

1 servings

1
  • 2 tablespoons all-purpose flour
  • 2 tablespoons granulated sugar
  • 2 tablespoons unsweetened cocoa powder
  • 2 tablespoons whole milk
  • 1½ tablespoons melted butter
  • 1 pinch of salt

Directions

  1. 1

    In a microwave-safe mug, whisk together the flour, sugar, cocoa powder, and salt until the dry ingredients are fully combined and lump-free.

  2. 2

    Pour in the melted butter and milk. Stir briskly until the batter is smooth, glossy, and uniform — about 1 minute of mixing.

  3. 3

    Microwave on full power for 1 minute. The edges should look set while the center remains slightly soft and fudgy.

  4. 4

    Check for doneness and add extra time in 10-second bursts if needed. Rest for 1 minute before eating, as the mug retains heat and continues cooking.

💡 Chef's Tip

Stir in a spoonful of peanut butter or a few dark chocolate chips before microwaving for an indulgent twist. Top with a scoop of vanilla ice cream while still warm for a restaurant-worthy dessert.
