Method
 

  1. In a large mixing bowl, beat the softened butter on medium speed for 2–3 minutes until light and creamy.

  3. Add the marshmallow fluff and beat for 1–2 minutes until airy and fluffy.
  4. Mix in the ground freeze-dried strawberries and strawberry puree until evenly combined.
  5. Add vanilla extract and a pinch of salt, then beat again to balance the sweetness.
