how to make Blackberry Frosting
Ingredients
- 1 cup fresh blackberries
- 2 tablespoons lemon juice
- 1 cup butter (2 sticks), room temperature
- 4 cups powdered sugar
- 1 teaspoon vanilla extract
- 1 tablespoon milk or cream (plus more if needed)
Directions
- Add the blackberries and lemon juice to a small saucepan. Over medium heat, bring the mixture to a simmer while stirring often. Let the blackberries soften and mash while cooking for about 20 minutes, until you have roughly 1/3 cup of thick blackberry puree.
- If you prefer a smooth frosting without seeds or skins, strain the blackberry puree through a fine mesh strainer. Alternatively, process it in a food processor to achieve a smoother texture. Allow the puree to cool completely to room temperature.
- In a large mixing bowl, add the softened butter and cooled blackberry puree. Use a mixer to beat them together until the mixture is smooth and evenly combined.
- 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.
- Add the milk or cream and vanilla extract to the frosting. Beat again to combine fully. Check the frosting’s consistency and if it’s too thick, add additional milk or cream one tablespoon at a time until the desired texture is reached.
- Once your cupcakes or cake are completely cooled, frost them with the blackberry buttercream. You can spread it smoothly or pipe it decoratively as you prefer.

tips to make Blackberry Frosting
