Using a paddle beater, beat softened butter on medium speed for about 3 minutes.
Add sifted confectioners' sugar and strawberry puree. Stir on low until incorporated, scraping the sides as needed.
Add the vanilla extract and 2 tablespoons of heavy cream. Beat on medium-high for 3 minutes or until light and fluffy, again stopping to scrape the sides once or twice.
If a thinner frosting is desired, add additional heavy cream 1 tablespoon at a time until desired consistency is reached.
