about 1½ cups frozen (or fresh) strawberries, thawed and pureed (you will need ½ cup of puree for the recipe)
½ teaspoon vanilla extract (some lemon or strawberry extract are real flavor boosters, if you have them)
1 pound confectioners' sugar (I tend to use less sugar than many recipes. If you like an extra sweet frosting, add more sugar.)
Instructions
Beat butter and cream cheese at medium speed with an stand mixer until creamy.
Beat in ½ cup of the strawberry puree and the vanilla (or other) extract. (The rest of the puree is leftover -- I drank it in my honey chia limeade -- the recipe is posted already.)
Gradually add confectioners' sugar, beating until smooth.
Spread frosting in between layers and on top and sides of cake (this is enough for a two layer 9 x 13-inch cake). Garnish with sliced fresh strawberries and Hello Kitty cake toppers, if desired. Keeps refrigerated for several days.
