In a large mixing bowl, whip 1 cup butter. Slowly add in 2 cups of powdered sugar. Mix until combined.
Addvanilla and powdered sugar. Add1 teaspoon vanilla and 1 more cup of powdered sugar and continue mixing. At this point you may need to add a teaspoon or two of milk to thin the frosting down.
Add remaining ingredients. Add in your last cup of powdered sugar and mix until combined. Add more or less milk depending on the consistency. You want the strawberry frosting to be thick, creamy and to be able to hold a point.
Crush: In a small blender, crush the freeze dried strawberries into a powder.
Fold in strawberries. Add the fresh and freeze dried strawberries.
