🛒 Ingredients

8 servings

8
  • 1 egg
  • ½ cup (125 ml) vegetable oil
  • 1 cup (250 ml) whole milk
  • 1 cup (200 g) sugar
  • 1 cup (100 g) sweetened chocolate powder (such as Nesquik)
  • 1 cup (120 g) all-purpose flour, sifted
  • 1 level tablespoon baking powder
  • 1 can (14 oz / 395 g) sweetened condensed milk
  • ¾ cup (200 ml) heavy cream
  • 4 tablespoons sweetened chocolate powder
  • Chocolate sprinkles to taste (optional)

Directions

  1. 1

    In a large bowl, whisk together the egg, oil, and milk until well combined.

  2. 2

    Add the sugar, chocolate powder, and sifted flour.

  3. 3

    Stir vigorously with a whisk or spoon until you get a smooth, lump-free batter.

  4. 4

    Add the baking powder and mix for a few more seconds to incorporate.

  5. 5

    Pour the batter into a lightly oiled microwave-safe dish.

  6. 6

    Microwave on high for 10 minutes. Check the doneness and add extra time if needed, depending on your microwave's wattage.

  7. 7

    Once cooked, leave the cake in the closed microwave for 5 minutes so it retains its moisture as it cools slowly.

  8. 8

    In a large, deep bowl, combine all the frosting ingredients and stir until well blended.

  9. 9

    Microwave in 2-minute intervals, stirring between each pass, until the frosting thickens to your desired consistency — either pourable or thick and creamy.

  10. 10

    Pour the warm frosting over the slightly cooled cake and top with chocolate sprinkles if desired.

💡 Chef's Tip

For an even moister crumb, use whole milk instead of semi-skimmed. If your microwave is powerful (1000 W or above), start with 8 minutes and check before adding more time. The frosting keeps well in the fridge — just warm it for 1 minute before serving.
