Creamy, fluffy and full of marshmallow flavor, this Marshmallow Fluff Frosting is perfect for cakes, cupcakes or to use as a filling. It’s so easy to mix up and sure to impress!
If your frosting turns out a bit runny, it may just be a bit warm. If your butter gets too warm this can happen. I recommend putting your frosting in the refrigerator for about thirty minutes and then mixing again.
