This easy 3-minute mascarpone frosting is a creamy, smooth, and lightly sweetened topping perfect for cakes and desserts. Made with cold mascarpone cheese, heavy cream, powdered sugar, and a touch of vanilla, it’s quick to prepare using an electric mixer and can be adjusted with cornstarch for a firmer texture, making it ideal for layering and decorating cakes.

  • Total Time: 5 minutes
  • Yield: Enough to frost a 9-inch layer cake (about 3 cups of frosting)

Ingredients

Frosting Ingredients

  • 500 g (17.6 oz) Mascarpone cheese – cold
  • 250 g (1 cup) Heavy cream – cold
  • 110 g (1 cup) Powdered sugar – sifted
  • 1 tsp Vanilla extract – optional for flavoring
  • 1-2 tablespoon Cornstarch – optional for firming up

Instructions

  1. Combine ingredients: In a mixing bowl, add the cold mascarpone cheese, cold heavy cream, sifted powdered sugar, and vanilla extract if using. Use an electric mixer set to medium speed to whisk the mixture.
  2. Whisk to smooth and thick: Continue mixing for about 1 minute until the frosting becomes smooth, thick, and creamy in texture, suitable for spreading or piping.
  3. Adjust firmness (optional): If you prefer a firmer frosting, gradually incorporate 1 to 2 tablespoons of cornstarch while whisking, stopping once you reach the desired consistency.
  4. Chill before use: Place the mascarpone frosting in the refrigerator to chill until ready to use, which helps it set and makes it easier to work with for smoothing layer cakes.

Notes

  • Store the mascarpone frosting in an airtight container in the refrigerator for up to 2 to 3 days to maintain freshness and texture.
  • Ensure mascarpone and cream are cold to achieve the best whipping results and smooth frosting texture.
  • If frosting separates or becomes too loose, refrigerate for 15-30 minutes and whisk gently again before use.
