Mango float is freezer-friendly. Depending on the brand of vegan heavy cream and vegan condensed milk you use, the texture of the cream layers may change a bit, but it will still taste delicious! If you'd like to freeze your cake, tightly cover it with plastic wrap followed by foil and store it for up to a month. This will help prevent freezer burn. Let thaw in the refrigerator until soft again and enjoy!
