Not only does it have a wonderful white chocolate flavor, but its creamy consistency is perfect for piping. It is the perfect choice for so many cake and cupcake flavors.

What I love most about this frosting recipe is that the white chocolate flavor really shines through.

The recipe calls for white baking chocolate (we really prefer this over white chocolate chips or candy melts). You are going to love the flavor.

How to Make White Chocolate Buttercream Frosting

*You can find the full, printable recipe card further down in this post. Here is a quick rundown of our steps!

This easy-to-follow recipe involves combining the melted white chocolate with the usual key players...butter, confectioners sugar, vanilla, and milk (or cream).

• Cut/chop the white chocolate into very small pieces, put into a microwave safe bowl and add 4 Tablespoons milk or cream. Chopping the chocolate into small pieces will help it to melt more quickly and evenly. 

• Microwave the chopped white chocolate in a microwave-safe bowl for 15 seconds and let sit for a minute, stir and microwave again 15 seconds letting it sit a minute to soften further, stir. (Repeat heating in small increments as needed).

We do it this way so that we do not accidentally overheat or burn the white chocolate. The heated chocolate will continue to melt as it is stirred. The melted chocolate should not be hot when added to the mixture and so allow to cool as needed.

• Beat the butter until softened and smooth, add the powdered sugar 1 cup at a time. Add the white chocolate and milk mixture. Add vanilla and salt. Add another Tablespoon milk if needed. Beat on medium speed for 3 to 4 minutes and it will become smooth and creamy.

• This recipe makes 5 cups frosting, which is enough to frost a 2 or 3 layer eight inch cake. If you will be doing a lot of decorative piping, you will need additional frosting.

If you've ever had Grainy Buttercream, Read this!

** We’ve had great results with Domino’s confectioner’s sugar in our frostings. Some brands of confectioner’s sugar don’t work as well with buttercream frosting recipes.  If a package doesn’t say pure cane sugar, it contains beet sugar which is more likely to give you a grainy outcome.

In addition to that, we’ve noticed that even some brands that say “Pure Cane Sugar” will give a grainy consistency. So frustrating! One example is Dixie Crystals (although it used to work great for us a few years ago.) Something has changed…it’s a mystery. Anyway, this recipe should not be grainy, and so if it is, experiment with a different brand of confectioners sugar.
