Cream Filling or Frosting

This is a recipe that I've been wanting for a long time. I've tried different filling recipes and none have been as good as this one! It's an amazing, fluffy white frosting that has more of a filling texture to me. I've used it to fill cupcakes and it would be a great cake filling. Try it, you might just want to frost something with it. -Sarah
