Perfect Party Frosting

Perfect Party Frosting. My favorite frosting to use on any celebration cake!

My Perfect Party Frosting is the ultimate sweet finish to any type of cake!

So I am pretty sure I am an expert on frosting. Some people have more useful talents, I suppose, but frosting happens to be mine.

Trust me, it’s taken many years to be sure it’s safe to use the word “expert”. But after many painstaking hours of taste-testing….many corner pieces consumed…I am officially official.

An official expert. At frosting…or rather at eating frosting. And to be able to eat all the frostings, I have had to make a whole heck of a lot of them too. Which brings me to today, and this Perfect Party Frosting.

It’s actually a version of the Marshmallow Buttercream Frosting I have in my book. Wait, you didn’t know I had a book? With a whole chapter dedicated to frosting? Go get you a copy quick!

The secret ingredient in this one is Marshmallow Fluff! It gives the frosting a great texture and consistency…you mix that together with butter, powdered sugar and a little bit of vanilla…

Then of course to make it party frosting you have to add sprinkles!!

Mix that all together and you’re set!

It’s so easy and I guarantee you will love it. You can certianly dig in with a spoon or cover your favorite cake with this creamy party frosting!

WACKY CAKE! This is an egg and dairy free cake recipe (without the frosting). You make it right in the cake pan, so NO MESS! You don't even grease the cake pan!

I’m going to be using this on a cake recipe next week that you won’t want to miss!!

It has worked out well for me so far, because as it turns out you guys all love sugary, buttery desserts too! It feels good to know you're not alone, doesn’t it?

Just had to come back on here and say this is still my favorite frosting!! It’s always a hit and people love that it’s not too sweet. They are always trying to guess that secret ingredient that makes them go hmmm (it’s the marshmallow fluff, of course!). Goes perfect with any cake, but I always love piping it onto my chocolate cupcakes. I could eat this stuff by the spoon, it’s that good!! So delicious!!

I’m usually able to pipe about 2.5 dozen cupcakes using a star tip.

Will this recipe toast up with a kitchen torch the way your other marshmallow whip does?

Just made this today with chocolate cupcakes for a meeting at work for Nurses Week. It was such a hit! They cleaned me out good and I ended up coming home with nothing! So good, I’m making it again tomorrow! Pipes like a dream!! It was enough to frost 2.5 dozen cupcakes using a star tip.

If I frost the cake the day ahead can I just let this sit out? Or does it all need to be refrigerated after?

My daughter requested the frosting for her birthday cake not be too sweet this year. I decided to try this recipe and it’s PERFECT. I’ll never make another white frosting again. I love mixing the sprinkles into the frosting too. Truly the perfect party frosting, thank you!!

Can you pipe this frosting on cupcakes and then leave them out? Does it hold up? Or is it a frosting that needs to be refrigerated?

Would this frosting work in lieu of the canned frosting used to make cake pops? I don’t like canned frosting so looking for an alternative.

Looks luscious! The marshmallow fluff sounds like a great addition! Yum!
