A Few Tips for the Best Blueberry Buttercream
Always use real butter for the creamiest texture. Avoid margarine or shortening, as they won’t provide the same rich flavor. If your butter is too soft, chill it slightly before mixing to avoid a greasy consistency.
Straining the blueberry reduction is crucial for a smooth, lump-free buttercream. Any leftover skin can create an uneven texture. A fine-mesh strainer helps ensure a silky consistency.
If you prefer a stronger blueberry flavor, double the amount of blueberries and reduce them down longer to concentrate the taste. A good nonstick saucepan will help prevent burning.
For an extra luxurious texture, substitute 1 tablespoon of the heavy cream with cream cheese. This adds a slight tang and makes the buttercream even richer. A stand mixer makes whipping it up even easier.
If your buttercream looks separated or too thin, chill it in the fridge for 10-15 minutes, then whip it again. A sturdy hand mixer will help bring it back together.
Blueberry Buttercream Frosting
Course: DessertDifficulty: Easy15
minutes5
minutesIngredients
½ cup fresh or frozen blueberries
1 tablespoon lemon juice
1 tablespoon sugar
1 cup unsalted butter, softened
3 cups powdered sugar
1 teaspoon vanilla extract
1 to 2 tablespoons heavy cream or milk (as needed)
Directions
- Start by making a blueberry reduction, which will give the frosting its rich color and flavor. In a small saucepan over medium heat, combine the blueberries, lemon juice, and sugar. Stir frequently and let the mixture simmer for about 5 minutes until the blueberries burst and release their juices. Mash the berries with a spoon and continue simmering until the mixture thickens into a syrup-like consistency. Strain the reduction through a fine-mesh sieve to remove the skins and let it cool completely before using.
- In a large mixing bowl, beat the softened butter using a hand mixer or stand mixer for about 2 minutes until smooth and creamy. Gradually add the powdered sugar, one cup at a time, beating well after each addition. This helps create a light, fluffy texture. Once all the sugar is incorporated, add the vanilla extract and beat again.
- Slowly drizzle in the cooled blueberry reduction, about a tablespoon at a time, while continuing to mix. The buttercream will start turning a beautiful shade of purple. If the consistency is too thick, add 1 to 2 tablespoons of heavy cream or milk to loosen it up slightly. If it’s too soft, add a little more powdered sugar until you reach your desired consistency.
- Continue beating the buttercream on medium speed for about 3 minutes until it becomes smooth, creamy, and holds stiff peaks. The longer you mix, the fluffier it will become. Taste and adjust if needed—if you want more tang, add a tiny squeeze of lemon juice, or for extra sweetness, another tablespoon of sugar.
- Use immediately to frost cakes, cupcakes, or cookies. If you’re not using it right away, store it in an airtight container in the refrigerator for up to 5 days. Before using, let it come to room temperature and whip it again to restore its fluffy texture.
- I personally love this with a cup of lemon tea – it’s super delicious!
