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)
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
