How to store frosted desserts

Make sure that you store desserts in an airtight container to keep them as fresh as possible for as long as possible.

You’re going to want to keep the air out so that they don’t dry out. This is true whether you’ve frosted the desserts or not.

Can you freeze desserts with frosting?

You can! Just add them to the freezer like you would if they didn’t have frosting and save them for later.

If you’re worried about the frosting, you can easily make it fresh once the dessert is unthawed and add it to the top.

Tips and Tricks

  • Keep in mind that this frosting recipe is so simple to make that you can easily make up one with alcohol and one without – so everyone can enjoy!
  • If you want to make your frosting a bit thicker, just add in some powdered sugar.
  • You can make the frosting ahead of time and have it saved and waiting in the fridge. This would be great for prepping desserts to have it handy earlier.
  • If you think that the frosting is too thick, you can always add a tad bit of coconut oil (liquid form) to the mix. And I mean a small amount. Stir it in and see if that helps to thin it out!
