In a mixing bowl, combine the softened cream cheese and unsalted butter. Beat them together using an electric mixer until smooth and creamy.
Gradually add in the powdered sugar, starting with 3 cups, and mix on low speed to prevent a sugar cloud. Once mixed, increase to medium speed and beat until well combined.
Add the pureed strawberries, vanilla extract, and a pinch of salt to the frosting mixture. Continue to mix on medium speed until the strawberries are fully incorporated and the frosting is light and fluffy. If you prefer a sweeter frosting, add more powdered sugar until you achieve your desired sweetness.
Taste the frosting and adjust flavors as needed, adding more strawberries for a stronger fruit flavor or more sugar for sweetness.
Once satisfied with the taste and texture, the frosting is ready to use. Spread it generously on cakes, cupcakes, or your favorite dessert.
Notes
Adjust sweetness by adding more powdered sugar if desired.
