With a bright blueberry flavor and pretty purple color, this Blueberry Cream Cheese Frosting is delicious and ready in minutes. (You can make this up to 24 hours ahead and store in a plastic zip-top bag in the fridge until ready to use.)
Place the freeze-dried blueberries into a blender or clean spice grinder. Grind into a fine powder.
Add to a medium bowl with the rest of the ingredients.
Blend well using a handheld electric mixer on high speed to make a fluffy frosting. OR stir with a whisk or spatula.
Transfer to a zip-top quart-size bag. Seal. Cut off 1 bottom corner and pipe onto cupcakes. (You can also just use a spatula to frost onto a cake or cupcakes.)
Notes
Let the cream cheese and butter soften at room temperature for a few hours so it's very soft to the touch. This will help it mix up smoothly.
Grind the blueberries to form a fine powder.
Add an additional ¼ cup powdered sugar to make the frosting sweeter if you'd like. (I sometimes do this if serving to older kids and/or adults who may expect a sweeter frosting.)
