Buttercream frosting is a combination of butter, powdered sugar, extract for flavor, and some milk or cream. The reason why everyone loves it to top their cakes and cupcakes is because it is super simple to make- takes about 5-10 minutes tops- and can be flavored virtually in any way you want!

We all know that chocolate frosting is absolutely delicious, but have you ever had white chocolate frosting? It’s a favorite among my homemade frosting recipes and is delicious on top of white chocolate cupcakes , white chocolate raspberry cupcakes or slathered all over as a frosting for white chocolate brownies.

It’s also the frosting I use for my spring favorite blackberry cake.

White chocolate is a deliciously sweet and creamy flavor that pairs perfectly with cakes and cupcakes. It’s also a beautiful frosting color for weddings and other special occasions!

Ingredients for white chocolate buttercream frosting.
  • Unsalted Butter – The smooth base of the frosting, butter adds a rich texture along with buttery flavor.
  • White Chocolate – Gives the frosting a smooth and creamy taste along with sweetness.
  • Confectioners Sugar – Blends into the frosting mixture to make it thick and sweet.
  • Heavy Cream – Helps thin out the frosting to the perfect consistency while keeping it creamy.


  1. Melt the white chocolate: Add the white chocolate to a microwave-safe bowl. Microwave it in 30-second intervals making sure to stir each time until fully melted. Let it cool for 5 minutes before mixing with the rest of the ingredients.
  2. Cream the butter and sugar: To a stand mixer, add the butter and sugar. Mix starting on low speed with the paddle attachment then moving to medium speed until creamy and fluffy. This should take 1-2 minutes.
  3. Add the white chocolate: Drizzle the melted white chocolate into the creamed butter and sugar mixture and continue to mix for a further minute until well combined and creamy.
  4. Add heavy cream: Add heavy cream to the mixture until the desired consistency is reached.

The best white chocolate to use

For the best flavor you want to use a white chocolate baking bar like Ghirardelli or Baker’s. White chocolate bars are better than chips because they contain cocoa butter and not oil like chocolate chips do. This results in a better flavor and higher quality chocolate!


This recipe makes enough frosting to fill and frost a 2 layer 8″ round cake, a 9×13 sheet cake, or frost 12 cupcakes.


  • The butter should be at room temperature before beginning the recipe. This allows it to cream together with the sugar more easily and results in a fluffier frosting. Learn how to soften butter quickly in 3 easy ways!
  • If you want a stiffer frosting, add less heavy cream. If you want a runnier/pouring consistency, add more heavy cream until desired consistency is reached.
  • The melted white chocolate should be cooled for at least 5 minutes to ensure that it doesn’t melt the butter when added.
  • Start mixing the butter and sugar together at low speed so the sugar does not fly out of the bowl then move to medium speed once the mixture is well combined.
  • To get smooth and creamy frosting, make sure all ingredients are mixed together until completely combined.

Storage: To store white chocolate buttercream, keep it in an airtight container at room temperature for up to a week or in the fridge for up to two weeks.

Freezing: This recipe can be frozen for up to three months. To freeze, place frosting in a freezer-safe bag and squeeze out as much air as possible before sealing. Thaw overnight in the fridge then bring it to room temperature before using.


What’s the best white chocolate to use for buttercream frosting?

I recommend using a premium white chocolate with a cocoa butter content of at least 30%. This will ensure that your frosting is smooth and creamy. I used Baker’s White Chocolate. White chocolate chips are not as high quality as a baking bar so it is preferred to use!

Can I use milk chocolate instead of white chocolate?

Yes, you can! Just keep in mind that the frosting will no longer be white in color but will have a light brown hue from the milk chocolate. The flavor will also be slightly different with milk chocolate being sweeter than white chocolate.

How do I make white chocolate buttercream less sweet?

If you find the frosting too sweet for your taste, you can add a touch of salt to balance out the sweetness. Start with ¼ teaspoon and add more to taste. You can also add in a little bit of lemon juice or zest for a tart flavor.

Can I use white chocolate chips?

Yes, you can use white chocolate chips though they may increase the sweetness in the recipe.
