🛒 Ingredients

8 servings

8
  • 8 tablespoons sweetened cocoa powder
  • 10 tablespoons granulated sugar
  • 1 tablespoon unsalted butter
  • 5 tablespoons whole milk
  • 1 pinch of salt

Directions

  1. 1

    Combine the cocoa powder, sugar, butter, and milk in a medium saucepan. Whisk together before placing over heat to prevent lumps from forming.

  2. 2

    Cook over medium heat, stirring continuously with a whisk or spatula, making sure to scrape the bottom of the pan to prevent sticking.

  3. 3

    Bring to a gentle boil, then continue stirring for 2–3 minutes until the filling thickens to a smooth, spreadable consistency that coats the back of a spoon.

  4. 4

    Remove from heat, stir in the pinch of salt, and allow to cool for 10 minutes before spreading over your cake layers.

💡 Chef's Tip

For an even richer result, substitute whole milk with heavy cream. A splash of vanilla extract adds wonderful depth of flavor. If the filling firms up before use, gently reheat it over a double boiler while stirring.
