This easy blueberry buttercream frosting is smooth, creamy, and packed with real blueberry flavor thanks to freeze-dried blueberries. It blends up beautifully with a naturally vibrant color and a sweet-tart finish that pairs perfectly with cakes, cupcakes, and cookies. Simple to make and full of bold blueberry flavor, it’s a quick way to elevate any dessert.
In the bowl of a stand mixer fitted with a paddle attachment or in a large mixing bowl with an electric hand mixer, whip the room temperature unsalted butter for 5 minutes until light, pale, and creamy.
Add half of the powdered sugar and mix on the lowest speed setting until fully combined. Add the remaining powdered sugar and continue to mix on low until fully incorporated.
Use a food processor to grind the freeze-dried blueberries into a fine powder. Then, add the freeze-dried blueberry powder to the frosting and mix on low speed until well incorporated.
Add the heavy cream, vanilla extract and salt and mix on low speed until combined. Scrape the bottom and sides of the bowl occasionally to ensure the ingredients are well mixed.
Increase the speed on the mixer to medium and whip the buttercream for about 2 to 3 minutes until it is smooth and creamy. Turn the mixer to low speed and mix the buttercream for several minutes to remove any air bubbles.
Optional: To smooth out the buttercream, heat 1 cup of the frosting in the microwave for 15 seconds. Pour the melted frosting back into the mixing bowl and mix the frosting on low speed until the buttercream is super smooth and creamy.
