This fresh blueberry buttercream frosting uses real blueberries to create a bright and sweet blueberry flavored frosting. Not only do you need just 4 ingredients, but it would go perfect on your favorite cake and cupcake recipes!
In a small or medium saucepan over medium heat, cook the blueberries until softened and they have released their juices. Over a small bowl, press the cooked berries through a fine-mesh strainer. Then discard the seeds. You should have about 4 tablespoons of blueberry sauce. Cool completely in the refrigerator.
In the bowl of an electric stand mixer using the paddle attachment, beat the butter on high speed until creamy (about 1-2 minutes). Add the powdered sugar, vanilla extract, and 4 tablespoons of the blueberry sauce and mix on low speed until combined (about 30 seconds).
Then increase the speed to high and beat for another 1-2 minutes until light and creamy.
Use it to frost your favorite cakes and cupcakes!
Notes
Room Temperature: The butter needs to be at room temperature in order to create the right consistency of buttercream frosting. If you start with cold butter, you'll have a difficult time getting the frosting to come together.
Blueberries: If you're pressed for time you could use a food processor to puree the blueberries instead of cooking them down. The blueberry flavor might not be as intense compared to cooking them down on the stove.
Baked Desserts: Make sure any dessert you use this frosting on is completely cooled before frosting. If not, the frosting will melt right off.
