White chocolate buttercream made with melted white chocolate and butter creates a silky, creamy frosting that’s ideal for cakes and cupcakes.
This buttercream blends melted white chocolate into a classic butter base for a smoother texture and a more delicate sweetness than traditional buttercream.
I use this tested version for both cakes and cupcakes because it spreads easily, pipes cleanly, and stays stable without feeling overly heavy.
Why you’ll love this recipe
- Smooth, creamy texture: easy to spread and pipe
- Balanced sweetness: milder than classic buttercream
- Great for decorating: holds shape on cakes and cupcakes
Ingredients You Need
- Unsalted butter: very soft, nearly creamy
- Powdered sugar: sifted to remove lumps
- Vanilla extract: pure vanilla or vanilla bean paste
- Heavy cream: full-fat, cold or slightly chilled
- White chocolate: good-quality, melted and cooled
Tips Before You Start
- Use very soft butter: it should be smooth and spreadable but not melted
- Cool the white chocolate: add it warm to lukewarm so it doesn’t melt the butter
- Sift powdered sugar: prevents a grainy finish
- Beat until light: whip until the frosting is airy and fluffy, not dense
- Adjust with cream: add a little cream if the frosting is too thick
How to Make White Chocolate Buttercream
Start with a reliable vanilla buttercream base and enrich it with melted white chocolate for extra smoothness and a subtle white chocolate flavor.
1. Beat the softened butter in a large bowl until it’s smooth, creamy, and free of lumps.
2. Add the sifted powdered sugar gradually—in two to three additions—mixing until fully combined and smooth.
3. Add vanilla and heavy cream, then continue beating on medium speed until the mixture is light and fluffy.
4. Pour in the melted white chocolate (cooled but still fluid) and beat until the frosting is completely smooth and evenly combined.
How to Use This White Chocolate Frosting
This versatile frosting works well on cakes, cupcakes, and many simple desserts.
- Spread on sheet cakes: smooth into an even layer for a clean finish
- Fill layer cakes: pipe or spread between layers for a creamy bite
- Pipe onto cupcakes: holds swirls and basic decorations nicely
- Top bars or brownies: adds a soft, creamy finish
- Chill slightly before piping: firms the frosting for tighter piping details
This frost pairs particularly well with light-flavored cakes like vanilla or soft white chocolate cakes.
Storage
Store the buttercream in an airtight container in the refrigerator for up to five days. Bring it to room temperature and rewhip briefly before using to restore its texture.
Variations
- Add a pinch of salt: offsets the sweetness
- Use vanilla bean paste: for a richer vanilla profile
- Make it lighter: add extra cream for a softer, spreadable consistency
- Whip longer: for an airier, fluffier finish
- Chill before piping: firms the frosting for sharper edges
You can also adapt the method to make a chocolate buttercream by using cocoa powder or melted dark chocolate instead of white chocolate.
Recipe Questions
Can I make this frosting ahead of time?
Yes. It stores well in the fridge for several days and can be rewhipped before use.
Why is my buttercream too soft?
If it’s too soft, the butter may have been too warm or the chocolate added while still too hot. Chill briefly and rewhip if needed.
Can I freeze this buttercream?
Yes. Freeze in an airtight container for up to one month. Thaw in the fridge, then bring to room temperature and rewhip.
Can I use it for layer cakes?
Yes. It holds well as both a filling and an exterior frosting for layer cakes.
How do I fix a grainy texture?
Ensure the powdered sugar is sifted and the butter is fully smooth before adding other ingredients. Rewhip to help smooth the texture.
