White chocolate frosting can be a hit-or-miss experience. Some versions taste overly sweet. Others melt too quickly or refuse to hold a shape. This recipe avoids both problems with a butter-based base that stays fluffy and smooth without turning runny or grainy.
In this post, you’ll learn how to make a white chocolate buttercream frosting recipe that blends richness with balance. It spreads easily, pipes cleanly, and complements a wide range of cakes without overwhelming them.
You’ll also get tips on consistency, ingredient swaps, and my personal notes on what works and what doesn’t. I’ve used this recipe across everything from a layered white chocolate cake to cupcakes for my niece’s birthday, and every time, someone asks for the recipe before the plates are cleared.
Why This White Chocolate Buttercream Works
There’s no shortcut to the right texture. I start by melting high-quality white chocolate not candy melts, not white chips. Real white chocolate with cocoa butter melts smoother and tastes cleaner. It creates the silkiness this white chocolate buttercream icing needs.
The butter must be soft, not melted. When I skip this step and rush the process, the frosting always ends up too loose. Creaming the butter first lets it catch the chocolate gently.
And then comes the powdered sugar. It’s important to sift it, even if you’re tempted to skip that bowl. You’ll thank yourself later when you see the smooth surface on your cupcakes.
Quick Note: This is a true white chocolate icing recipe, not a glaze. It holds shape, supports layers, and doesn’t slide off once piped.
Ingredients That Actually Matter
I’ve tried this frosting with various types of white chocolate, and the difference is clear. White chips tend to have added stabilizers and palm oil, which give the final frosting a waxy texture and less flavor.
Use a bar of real white chocolate. I look for ones that list cocoa butter in the top three ingredients. Brands like Lindt or Green & Black’s melt down without a fight and give the frosting that smooth, melt-in-the-mouth texture.
When I made this frosting for my Red Velvet Cake, the white chocolate brought out the cocoa tones without adding extra sweetness. That cake needed something soft and light to contrast the dense crumb, and this frosting held up beautifully.
Step-by-Step: How to Make White Chocolate Buttercream
Start with melting the chocolate
You need a slow and gentle heat. I prefer the double boiler method because it gives me more control, but if I’m short on time, I use the microwave in short bursts. Once it’s melted, I let it cool just slightly. If it’s too warm, it’ll melt the butter. If it’s too cold, it’ll seize.
Beat the butter
This step takes more time than most expect. I whip it for at least 2 minutes, sometimes 3, until it’s pale and fluffy. If you underbeat it, you miss the chance to build air into the base. That air gives the frosting lift.
Combine the chocolate and butter
I pour the cooled chocolate in slowly while the mixer’s on low. Then I pause to scrape the bowl and beat again. This step is where the frosting starts to form its final body. You’ll notice it thickening and turning glossy.
Add the powdered sugar
Sift first. Then add slowly. If you dump it all in, you’ll end up with clumps or a dusty mess. Once incorporated, I turn up the speed and give it a good beat for 1–2 minutes until it fluffs up again.
Finish with cream and vanilla
This last step pulls it all together. The cream adds lightness and gives you control over texture. I use heavy cream, but whole milk works if that’s what I have. The pinch of salt tones down the sweetness, and the vanilla rounds out the flavor.
Ingredient Comparison: White Chocolate Chips vs Real White Chocolate Bars
I’ve tested both in side-by-side batches. Chips may seem easier, but they melt unevenly and leave a grainy finish. Even when they look smooth, the frosting sets too soft and feels waxy on the tongue.
Real white chocolate bars, on the other hand, melt with clarity. The texture is silkier, and the taste carries subtle cocoa butter notes that make a difference especially if you’re pairing the frosting with something light, like White Chocolate Cake.
If you’re frosting cupcakes for a bake sale or filling layers of sponge, go with the bar. Your piping will look cleaner, and the flavor stays more balanced.
Serving Suggestions and Storage Tips
You can use this white frosting recipe for cake layers, piping rosettes, or as a filling between cookies. For something lighter, pair it with chiffon or angel food cake.
If you’re after a fluffier texture, take a look at my Whipped Cream Frosting. It doesn’t have the structure this buttercream does, but it’s ideal for shortcakes and simpler bakes.
For a chocolate variation, my Whipped Chocolate Frosting brings the same smoothness with a cocoa twist.
Once made, this frosting can sit at room temperature for a few hours. If you’re prepping ahead, store it in the fridge for up to 3 days, then bring it back to room temperature and rewhip before using. I’ve frozen it as well, though I prefer using it fresh for best texture.
Related Recipes You Might Love
You can also try this on a sturdy cake like my Cool Whip Cream Cheese Frosting cake or use it as a contrast to deeper cocoa layers topped with Chocolate Buttercream.
It also makes a surprisingly good combo with red fruits. Think raspberry compote or a thin layer of strawberry preserves under the frosting. Just a thin smear it cuts through the richness and adds brightness.
Final Thoughts and Tips from My Notebook
If your frosting feels too loose, chill it for 10 minutes and rewhip. That usually brings it back together without losing volume.
This white chocolate buttercream frosting recipe works for celebrations or smaller bakes. It pipes cleanly, sets well, and keeps its shape even on warmer days. I’ve even used it for cupcake bouquets, where the details matter.
One thing I’ve learned: don’t overthink the flavor. Let the white chocolate do the work. With the right ingredients and a little patience, this frosting becomes a favorite you’ll come back to again.

Ingredients
- 200g white chocolate, chopped (use high-quality chocolate with cocoa butter)
- 225g unsalted butter, softened
- 250g powdered sugar, sifted
- 2 tablespoons heavy cream or milk, plus more if needed
- 1 teaspoon pure vanilla extract
- Pinch of salt
Instructions
- MELT THE CHOCOLATE: Place chopped white chocolate in a heatproof bowl. Gently melt over a double boiler or in the microwave using 20-second bursts, stirring after each burst until fully smooth. Let it cool slightly until lukewarm but still pourable.
- BEAT THE BUTTER: In a large bowl, beat the softened butter on medium-high speed for 2 to 3 minutes until pale, smooth, and creamy. This helps create a light texture.
- ADD THE MELTED CHOCOLATE: With the mixer on low, slowly stream in the cooled white chocolate. Scrape down the sides of the bowl and continue beating until fully combined.
- INCORPORATE THE SUGAR: Add sifted powdered sugar gradually, mixing on low to start, then increasing to medium-high speed once incorporated. Beat for another 1 to 2 minutes until fluffy.
- FINISH WITH LIQUIDS: Add the vanilla extract, pinch of salt, and 2 tablespoons of cream. Beat on medium speed until the frosting is smooth. Adjust the consistency with more cream, 1 teaspoon at a time, if needed.
- USE AS DESIRED: The frosting is now ready to spread on cakes, pipe onto cupcakes, or use between cake layers.
Notes
For best results, use white chocolate that lists cocoa butter as a main ingredient. Avoid chips or candy melts, which can result in a waxy texture. If the frosting is too soft after mixing, chill it briefly and rewhip before using.
