A special ingredient packs this frosting with strawberry flavor—and keeps it extra-creamy!
Place strawberries in large zipper-lock plastic bag. Press out as much air as possible, then seal bag. Use rolling pin to gently pound strawberries into powder.
In bowl of stand mixer (or large bowl if using handheld mixer), combine softened cream cheese, softened butter, sour cream, vanilla, salt, and strawberry powder. Lock bowl into place and attach paddle to stand mixer, if using.
Start mixer on medium speed and beat until smooth, about 1 minute. Stop mixer. Use rubber spatula to scrape down sides of bowl.
Start mixer on low speed. Slowly add sugar, a little bit at a time, and beat until smooth, about 4 minutes.
This frosting is a perfect pastel strawberry pink. And it comes from a very special ingredient. Yes, they are strawberries, but not fresh! Freeze-dried strawberries are the key to this fresh-tasting pink frosting. Freeze-dried strawberries are frozen, they’ve just had all their water removed. They aren’t heated during this process, so they retain a lot of their natural fruity flavor. We like to use them in this frosting for exactly that reason—they taste great and won’t make our frosting soupy! (Freeze-dried strawberries can be found at well-stocked grocery stores or online.)
