🛒 Ingredients

1 servings

1
  • 1 can (14 oz / 395 g) sweetened condensed milk
  • ¾ cup (200 ml) heavy cream
  • 4 tablespoons sweetened cocoa powder
  • Chocolate sprinkles for topping

Directions

  1. 1

    In a large microwave-safe bowl, combine the condensed milk, heavy cream, and cocoa powder.

  2. 2

    Rinse the empty condensed milk can with a splash of heavy cream to collect every last drop, then add to the bowl.

  3. 3

    Stir until smooth and completely combined.

  4. 4

    Microwave on high for 7 minutes, pausing halfway through to stir thoroughly.

  5. 5

    Immediately pour the hot frosting over a warm cake so it sets with a smooth, glossy coat.

  6. 6

    Top with chocolate sprinkles before the frosting firms up.

💡 Chef's Tip

Use a deep bowl — the mixture can bubble up during cooking. Stir in a small knob of butter right after removing from the microwave for an extra glossy finish.
