White chocolate buttercream may look like plain old frosting, but the flavor and texture will tell you otherwise. So if you are looking for a way to add more flavor to buttercream but still want white frosting that works for piping or spreading, you are in luck!

White chocolate lovers, you are in the right place. This delicious buttercream is fluffy, flavorful, and perfect decorating cakes, cupcakes, and more.
This frosting is good. I mean really good!
You would think adding so much melted white chocolate to the buttercream would weigh it down and make it heavy, but it doesn’t. It is so light and fluffy and has a great flavor.
I got this recipe from my sister-in-law several years ago. She is quite the cake artist, so I take her recommendations pretty seriously.

She has been using this white chocolate frosting as a base for her fondant rather than using a classic buttercream, and it knocked my socks off. It is a great way to add another layer of flavor.
Plus, she prefers it because she doesn’t like how much some buttercreams taste like powdered sugar. The melted chocolate allows you to use a little less confectioners sugar and gives you a really smooth result.
Why We Love This White Chocolate Frosting
It is extra rich and creamy thanks to the melted white chocolate. Yet it is still easy to make.
It spreads like a dream, so it works well for filling, crumb coating, or final coating a cake.
It works great for piping as well. Making it perfect for decorations, borders, or big fluffy swirls on cupcakes.

It goes well with so many different flavors. Almost anything goes with white chocolate. Especially berries, other fruits, peanut butter, and more.
While it has added flavor, this frosting is still nice and white. That makes it perfect for wedding cakes and other instances when you want a nice white base.
However, it also takes color well. So you can dye it with food coloring gel and make any color you would like.

If you aren’t a fan of super sweet frostings, this recipe has a bonus for you. The powdered sugar to butter ratio is much lower than most American buttercream recipes.
The addition of white chocolate helps give it stability without needing all that powdered sugar. So it is less sweet than a lot of frostings.
Tips and Tricks
Start with good quality white chocolate. You can find bars in the baking aisle or in the candy aisle. Make sure it is actual white chocolate made with cocoa butter.

White chocolate melts at a lower temperature than darker chocolate, and it scorches easily, too. So microwave it it short 10 second intervals, stirring after each one, until it just stirs smooth.
Melt the white chocolate before you start anything else. That will give the melted chocolate a chance to cool before you add it to the buttercream mixture.


You are going to want to make sure your butter is at room temperature before you start. If the butter and sugar mixture is still cool when you add the white chocolate, you increase your chance of getting little bits of congealed chocolate in your frosting.
If your butter is brought all the way to room temperature and your white chocolate is cooled but still liquid, it should incorporate nicely. Just keep the mixer going and drizzle it in!


If you need to store your frosting, place it in an airtight container. You can leave it on the counter for several hours or even overnight.
For longer storage, you can refrigerate it for up to a week or freeze it for up to 3 months. Just bring the frosting back to room temperature and rewhip before using.

I’ve never had such a perfectly light and fluffy frosting. I’ve been baking for years and this is hands down my favorite! Thank you

What temperature does the white chocolate need to be before adding it to the buttercream? I am so worried about adding it when it is too hot and causing it to seize. Thanks.

I've never taken a temperature, which I know isn't very helpful. So I am sorry about that. White chocolate has a lower melting temperature than regular chocolate. So you want to be careful when melting it so it doesn't scorch and seize at that point. I melt the white chocolate before I start anything else, then let it cool while I get everything else ready. So it probably sits for about 10 minutes by the time I get back to it. It should feel maybe lukewarm, but not at all hot. The good thing is, if you either drizzle it in or add it in small bits, the volume of warm chocolate to the rest of the ingredients is low and with the mixer running it will cool quickly. Using that method I've never had it melt the butter or form little chunks of white chocolate in the frosting. If everything is pretty close to room temperature, you should be in good shape! If you are really worried, you could add some of the heavy whipping cream to the white chocolate when you melt it and basically make a white chocolate ganache to add to the frosting.

Is it possible to provide the ingredient list with gms as the measurement unit?

I wish recipes were easily converted. I don't cook in grams often, so I'd have to use a calculator to convert it. I am not sure how accurate those are, so I'm hesitant to do it.

Carlee, I used this buttercream on my Raspberry Filled Cupcakes. It was divine. There's just no other word for it!! I did short the cream just a tad because I wanted to pipe so I wanted it just a bit stiffer and it looked (and tasted) gorgeous!
Thanks much for the recipe, and I linked my Cupcakes up to here for your recipe.
