Step 1

Use a food processor to grind the freeze-dried raspberries into a fine powder. Set aside.

Step 2

In a large mixing bowl, beat the butter with an electric mixer on medium speed until creamy and smooth, about 5 minutes.

Step 3

Add the raspberry powder and one cup of the confectioners; sugar. Beat on low speed until well mixed in. Gradually add the remaining sugar, mixing well after each addition.

Step 4

Add the vanilla, salt, and two tablespoons of heavy cream. Mix on medium-low until combined. Continue to add as much of the remaining heavy cream needed to make a smooth spreadable frosting.

Step 5

Turn the speed up to medium-high and beat until light and fluffy. Scrape down the sides of the bowl as needed.
