4.6 from 50 reviews

This Blackberry Frosting is a luscious, creamy buttercream infused with fresh blackberry puree and a hint of lemon juice. Perfect for adding a vibrant color and a burst of fruity flavor to cupcakes, cakes, or any dessert, this frosting combines the rich taste of butter with the natural sweetness and tang of blackberries, balanced by vanilla and a smooth, spreadable texture.

Ingredients

Scale

Blackberry Puree

  • 1 cup fresh blackberries
  • 2 tablespoons lemon juice

Frosting

  • 1 cup butter (2 sticks), room temperature
  • 4 cups powdered sugar
  • 1 teaspoon vanilla extract
  • 1 tablespoon milk or cream (plus more if needed)

Instructions

  1. Prepare Blackberry Puree: Add blackberries and lemon juice to a small saucepan. Over medium heat, bring the mixture to a simmer, stirring often. Let the blackberries soften and mash for about 20 minutes until you have roughly 1/3 cup of thick blackberry puree.
  2. Strain Puree (Optional): For a smooth frosting without seeds or skins, strain the puree through a fine mesh strainer or process it in a food processor to achieve a smoother texture. Allow the puree to cool completely to room temperature.
  3. Combine Butter and Puree: In a large mixing bowl, add the softened butter and the cooled blackberry puree. Use a mixer to beat them together until the mixture is smooth and evenly combined.
  4. Add Powdered Sugar: Gradually add the powdered sugar to the butter and puree mixture, beating on medium-high speed until the frosting is smooth, creamy, and well incorporated.
  5. Incorporate Milk and Vanilla: Add the milk or cream and vanilla extract to the frosting. Beat again to fully combine. If the frosting is too thick, add additional milk or cream one tablespoon at a time until desired consistency is reached.
  6. Frost Your Dessert: Once cupcakes or cake are completely cooled, frost them with the blackberry buttercream. Spread smoothly or pipe decoratively as desired.

Notes

  • Straining the blackberry puree is optional but recommended if you want a seed-free, smooth frosting.
  • Adjust the milk or cream quantity to achieve your preferred frosting consistency.
  • Ensure the cake or cupcakes are completely cooled before frosting to prevent melting.
  • This frosting pairs beautifully with vanilla, lemon, or almond-flavored cakes.
