Ingredients
Non-Dairy Butter: I like Soy-Free Earth Balance or Country Crock Plant Butter Sticks best. If you are not dairy-free, you can also use unsalted butter. Be sure your butter is at room temperature for the smoothest frosting!
Freeze-Dried Blueberries: Freeze-dried blueberries add all the blueberry flavor without adding too much liquid. I usually get my freeze-dried fruit at Trader Joes, but you can also get freeze-dried blueberries on Amazon!
Powdered Sugar: Powdered sugar adds structure and sweetness. Be sure to sift it!
Lemon Juice: Lemon juice brings the blueberry flavor out!

Expert Recipe Tips
Be sure to sift the ground freeze dried blueberries! There will be a lot of seeds that will make your frosting gritty if you don't sift them out.
And for the smoothest frosting, be sure to sift the powdered sugar!
Also, stop mixing and scrape the bowl down regularly to ensure that everything is mixed evenly.
