🛒 Ingredients

20 servings

20
  • 1 can sweetened condensed milk (14 oz / 397 g)
  • 4 tablespoons unsweetened cocoa powder
  • 1 tablespoon unsalted butter
  • 2 tablespoons heavy cream
  • 1 teaspoon pure vanilla extract

Directions

  1. 1

    In a medium heavy-bottomed saucepan, whisk together the sweetened condensed milk and cocoa powder over low heat until completely smooth with no lumps.

  2. 2

    Add the butter and heavy cream, then cook over medium-low heat, stirring continuously for 5 to 7 minutes, until the mixture thickens to a spreadable consistency.

  3. 3

    Remove from heat, stir in the vanilla extract, and allow the filling to cool for 10 minutes before assembling.

  4. 4

    Spread generously between cake layers and refrigerate the assembled cake for at least 30 minutes before slicing for the best texture.

💡 Chef's Tip

For a deeper chocolate flavor, swap half the cocoa powder for melted 70% dark chocolate. This filling keeps well in the fridge for up to 3 days in an airtight container.
