Fruit Puree
- 1 cup fresh blackberries
- 2 tablespoons lemon juice
Frosting Base
- 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 blackberries and lemon juice to a small saucepan. Over medium heat, bring the mixture to a simmer while stirring frequently. Let the blackberries soften and mash during about 20 minutes of cooking until you have roughly 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. Alternatively, process it in a food processor for a finer texture. Allow the puree to cool completely to room temperature.
- Combine Butter and Puree: In a large mixing bowl, add the softened butter and cooled blackberry puree. Use an electric mixer to beat them together until the mixture is smooth and fully combined.
- Add Powdered Sugar: Gradually add the powdered sugar to the butter and puree mixture. Beat on medium-high speed until the frosting is smooth, creamy, and well incorporated.
- Incorporate Milk and Vanilla: Add the milk or cream and vanilla extract to the frosting. Beat the mixture again to combine fully. Check the consistency and, if too thick, add additional milk or cream one tablespoon at a time until you reach the desired texture.
- Frost Your Dessert: Once your cupcakes or cake are completely cooled, frost them with the blackberry buttercream. You can spread it smoothly or pipe it decoratively as preferred.
Notes
- For a seedless frosting, straining the blackberry puree is recommended but optional depending on your texture preference.
- If fresh blackberries are not available, frozen blackberries can be used; thaw and drain excess liquid before cooking.
- Add milk or cream gradually to avoid making the frosting too runny.
- Store leftover frosting in an airtight container in the refrigerator for up to 5 days. Bring to room temperature and rewhip before use.
- This frosting pairs beautifully with vanilla, lemon, or chocolate cakes and cupcakes.
