🛒 Ingredients

8 servings

8
  • 1 can sweetened condensed milk (14 oz / 397 g)
  • 1 can light cream or heavy cream (7 oz / 200 ml)
  • 1 tablespoon cornstarch
  • 4 tablespoons sweetened cocoa powder (such as Nesquik)

Directions

  1. 1

    Combine the condensed milk, cream, cornstarch, and cocoa powder in a medium saucepan.

  2. 2

    Cook over low heat, stirring constantly with a spatula or whisk, until the mixture thickens enough to coat the back of a spoon (8-10 minutes).

  3. 3

    Remove from heat and let it cool for 2 minutes — it will continue to set slightly as it rests.

  4. 4

    Slice the cake horizontally in half. Spread the warm filling generously over the bottom layer.

  5. 5

    Place the top layer back on and pour the remaining filling over the top, letting it drip down the sides for a glossy finish.

💡 Chef's Tip

Adjust the amount of cocoa to control the intensity of the chocolate flavor. For a richer result, use full-fat heavy cream instead of light cream.
