Ingredients

Blueberry Sauce

Buttercream Frosting

  • cups butter
  • 5 cups powdered sugar
  • ¾ cup blueberry sauce, approximately (use all of the blueberry sauce made)

Instructions

Blueberry Sauce

  • In a small saucepan, add fresh blueberries, sugar, lemon juice, and cornstarch.
  • Heat over medium heat, and cook until the blueberries have burst and the sauce has thickened, stirring constantly. Remove from heat and let cool.

Buttercream Frosting

  • Beat the butter until it is light and creamy.
  • Gently add the powdered sugar and beat until well blended.
  • Next, add all of the blueberry sauce once it has cooled completely.
  • Beat until well combined.
  • *Makes enough frosting for a 3-layer 9-inch cake, 24 cupcakes, or a sheet cake.

Notes

Tips
  • Let the blueberry sauce cool completely before mixing it into the frosting.
  • Use room temperature butter for the smoothest texture.
  • Beat the butter until light and fluffy before adding sugar.
  • If the frosting is too soft, chill it for 15-20 minutes before piping.
