Fresh Strawberry Frosting - cooking recipe

Ingredients

1/3 cup butter
3 cups powdered sugar
1 1/2 teaspoons vanilla
9 fresh strawberries (not frozen)

Preparation

In mixer, combine butter, sugar and vanilla.
Add strawberries, one at a time, until you reach the desired consistency.
I wouldn't use frozen strawberries for this recipe.
For a smaller cake, the Zaar conversion isn't quite right. Here is what I do:
10x13 or two layer cake: 2 cups powdered sugar to just under 1/4 c butter.
9x9 or one layer cake: 1 cup powdered sugar to just under 2 T butter.
