Make the frosting: Using a blender or food processor, process the freeze-dried strawberries into a powdery crumb. You should have around 1/2 cup. Set aside. In a large bowl using a hand-held or stand mixer fitted with a paddle or whisk attachment, beat the butter for 1 minute on high speed until completely smooth and creamy. Add the confectioners’ sugar, strawberry powder, melted and cooled white chocolate, 2 Tablespoons heavy cream, vanilla extract, and salt and beat on medium-high speed until combined and creamy. Add 2 more Tablespoons of heavy cream to slightly thin out, if desired. Taste, then add another pinch of salt if desired.
