This vegan frosting is easy and so delicious! I made a large cake. However, I ate too much. I had to make another batch! This thick marshmallow fluff  icing is great for decorating cakes and cupcakes as well as simple piping. . Additionally you can add your favorite extract or food coloring for festive occasions and birthdays .

I can make this easy dairy-free marshmallow whipped cream fluff icing for any occasion. For example I made this with green food coloring to make a Minecraft themed cake for my son’s 7th birthday. He said it looked “derpy” , whatever that means. I make easy marshmallow frosting anytime I bake a cake. It’s so simple to make and only takes about 15 minutes at the most.

Non vegan Buttercream frostings often have egg yolk, and marshmallows generally contain gelatin. Gelatin is in many sugary products. It renders foods no longer vegan. It is a gelatinous ingredient made from pork and other animal materials. This  contains none of that. 

Vegetable Shortening Versus Vegan Butter

Why do I use vegetable shortening over some kind of dairy free butter substitute? Marshmallow Buttercream Fluff Frosting requires only 3 ingredients. The first ingredient is vegetable shortening. It is thick and creamy. This product creates fluffy gooey frosting. That is why I prefer it, due to its thick consistency and texture. In fake, it’s solid at room temperature. So if you really want that super thick texture, this is the ingredient to choose.

The texture should be thick and smooth

Also vegetable shortening is rather flavorless, allowing your icing using Smuckers marshmallow topping fluff, vanilla extract, and powdered sugar to really stand out and produce maximum flavor. The fake buttery flavor of dairy free butter tends to overwhelm the palate. 

What is Smuckers Marshmallow Topping?

Unfortunately Marshmallows are not vegan. Due to the fact that they contain gelatin. The gelatin creates shape. However marshmallow cream does not need gelatin.

Smuckers Marshmallow Topping IS vegan. It fluffs up with the shortening and sugar really well. I found it near the chocolate syrup at my local grocery store. It adds the yummiest flavor to vegan frostings.

Tips & Tricks 

Vegetable shortening, powdered sugar, and Smuckers need to all be room temperature before mixing otherwise it won’t mix smoothly and will become chunky.

Sift your powdered sugar, especially if it’s ever been refrigerated. Otherwise you will surely end up with chunks in your end result. 

It is important to use an electric mixer for extra whipped dairy free marshmallow fluff frosting. Start with the vegetable shortening ingredient. Blend it alone first to break it up. Then Add the marshmallow fluff topping and blend with the mixer.

Blend Vegan smuckers marshmallow shortening mixture into a thick paste. Then Add powdered sugar last. Add the sugar one cup at a time and blend in between. Otherwise you will cause a powder sugar explosion!

Blend the dairy free marshmallow fluff buttercream frosting thoroughly, it should be thick and fluffy. This frosting tastes delicious on cakes and bakes!
