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 fresh blackberries and lemon juice to a small saucepan over medium heat. Stir often as the mixture comes to a simmer, allowing the blackberries to soften and mash while cooking for about 20 minutes until you obtain approximately 1/3 cup of thick 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 to achieve a smoother consistency. Let the puree cool completely to room temperature before proceeding.
  3. Combine Butter and Puree: In a large mixing bowl, add the softened butter and the cooled blackberry puree. Using a mixer, beat the two together until the mixture becomes smooth and evenly combined.
  4. Add Powdered Sugar: Gradually incorporate the powdered sugar into the butter and puree mixture. Beat on medium-high speed until the frosting is creamy, smooth, and fully incorporated.
  5. Incorporate Milk and Vanilla: Add the milk or cream along with the vanilla extract to the frosting. Beat again to fully combine. If the frosting is too thick, add additional milk or cream by tablespoon increments until you reach your desired texture.
  6. Frost Your Dessert: Once your cake or cupcakes are completely cooled, frost them with the blackberry buttercream. Spread the frosting smoothly or pipe it decoratively as desired.

Notes

  • Straining the blackberry puree is optional but recommended if you prefer a seedless texture in your frosting.
  • Adjust the amount of milk or cream to get the perfect frosting consistency for spreading or piping.
  • Use room temperature butter to ensure a smooth mixture and easy blending.
  • This frosting pairs beautifully with vanilla, lemon, or chocolate cakes for a fruity twist.
