4.6 from 74 reviews

This Blackberry Frosting Recipe is a luscious, creamy topping made from fresh blackberries, butter, powdered sugar, and a hint of vanilla. Perfect for cakes and cupcakes, it combines the natural tartness of blackberries with smooth buttercream for a vibrant and flavorful finish.

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 the blackberries and lemon juice to a small saucepan. Heat over medium heat, bringing the mixture to a simmer while stirring frequently. Cook for about 20 minutes until the blackberries soften and mash, yielding approximately 1/3 cup of thick blackberry puree.
  2. Strain Puree (Optional): For a smooth frosting without seeds or skins, strain the blackberry puree through a fine mesh strainer or process it in a food processor for a smoother texture. Let the puree cool completely to room temperature before using.
  3. Combine Butter and Puree: In a large mixing bowl, add the softened butter and the cooled blackberry puree. Beat them together using a mixer until the mixture is smooth and well combined.
  4. Add Powdered Sugar: Gradually add the powdered sugar to the butter and puree mixture. Beat on medium-high speed until the frosting becomes smooth, creamy, and fully incorporated.
  5. Incorporate Milk and Vanilla: Add the milk or cream along with the vanilla extract to the frosting. Beat again until fully combined. Assess the consistency and add more milk or cream, one tablespoon at a time, if the frosting is too thick, until the desired texture is achieved.
  6. Frost Your Dessert: Once your cake or cupcakes are completely cool, spread or pipe the blackberry buttercream frosting decoratively as desired.

Notes

  • If you prefer seedless frosting, straining the blackberry puree is recommended.
  • Adjust the amount of milk or cream to get the perfect frosting consistency for spreading or piping.
  • This frosting pairs well with vanilla, lemon, or chocolate cakes.
  • Store leftover frosting in an airtight container in the refrigerator for up to 3 days; bring to room temperature and re-whip before using.
