Step 1

Puree the raspberries and then run the pureed raspberries through a sieve. (You should have 1/2 cup of Raspberry puree.)

Step 2

Add the softened butter and the raspberry puree and mix until they are completely combined.

Step 3

Add half of the powdered sugar.

Step 4

Continue to beat on medium speed until the frosting is creamy.

Step 5

If the frosting is too thin, add 1/2 cup additional powdered sugar. Keep adding powdered sugar 1/2 cup at a time until you have the frosting at the desired consistency.

Step 6

If the frosting is too thick/dry, put a little bit of water in the raspberry puree container that you used and then add this liquid to the frosting 1 tsp. at a time until you get the desired consistency.
