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 fresh 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, allowing the blackberries to soften and mash down until you achieve 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. 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. Use an electric mixer to beat them together 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 is creamy, smooth, and fully incorporated.
- Incorporate Milk and Vanilla: Add the milk or cream and vanilla extract to the frosting. Beat again until well combined. Adjust the consistency by adding more milk or cream, one tablespoon at a time, if the frosting is too thick.
- Frost Your Dessert: Once your cake or cupcakes have cooled completely, frost them with the blackberry buttercream. You can spread it smoothly or use a piping bag to create decorative designs as desired.
Notes
- Straining the blackberry puree is optional but recommended for a seed-free frosting.
- If the frosting is too thick, add milk or cream gradually to reach desired consistency.
- Use fresh blackberries for the best flavor; frozen can be used but may require extra cooking time.
- Store leftover frosting in an airtight container in the refrigerator for up to 3 days. Rewhip before using.
- This frosting pairs beautifully with vanilla, lemon, or chocolate cakes.
