🛒 Ingredients

5 servings

5
  • 2 tablespoons unsweetened cocoa powder
  • 2 tablespoons granulated sugar
  • 1 tablespoon unsalted butter
  • 1 tablespoon whole milk

Directions

  1. 1

    Combine the cocoa powder, sugar, butter, and milk in a small saucepan.

  2. 2

    Heat over low heat, stirring constantly, until the butter melts and the sugar fully dissolves, about 2–3 minutes.

  3. 3

    Remove from heat as soon as the mixture is smooth and glossy. Let it cool for one minute.

  4. 4

    Drizzle over cold ice cream or cake and watch it harden into a crispy shell within seconds.

💡 Chef's Tip

For an extra-crunchy shell, stir in half a teaspoon of melted coconut oil. Leftovers keep in the fridge for up to 3 days — reheat gently in a double boiler before using.
