All-Natural Pink Frosting!
Beat confectioners' sugar, butter, strawberry puree, and vanilla extract together in the bowl of a stand mixer or using a hand-held mixer, gradually increasing speed to reach high, until smooth.Advertisement
Softening the butter first generally makes the mixing process more simple.
If you desire a thicker icing add less puree or more sugar. One trick I tried was using a little xanthan gum, about a teaspoon.
