White Chocolate Buttercream Frosting is a smooth American buttercream that has the best white chocolate flavor. The frosting adds melted white chocolate to my vanilla buttercream frosting (with a few changes so the sweetness is perfect) to make the perfect creamy icing for any flavor cupcake. You can use a piping tip, frost a layer cake, sheet cake, or cupcakes – this frosting is delicious and just melts in your mouth.

Ingredient Notes

  • White Chocolate Bar: I use a baking chocolate bar because it melts easiest and tastes the best; white chocolate chips do not have the same effect in this recipe. Use a good quality baking bar, like Ghirardelli. Break the bar into small pieces so it melts easier.
  • Milk: You can use any kind of milk, heavy whipping cream, half and half, or nondairy milk. Just remember the more fat your milk has the more you might need.
  • Butter: I use unsalted butter because I like to be in charge of how much salt goes into a recipe.

How to make White Chocolate Frosting

  1. To melt white chocolate, place it in to a microwave safe bowl. Heat at 50% power for 1 minute; stir then heat in 30 second increments until the chocolate is melted.
  2. I always start by creaming my butter and powdered sugar (also called confectioners’ sugar or icing sugar). You can use a stand mixer fitted with the paddle attachment or a hand mixer.
  3. Once you mix in vanilla and white chocolate, you’ll want to add a bit of milk or cream. Start with just a bit and work up (you can always add but you can’t easily remove it).

Expert Tips

  • Frosting too sweet? Add a pinch of salt and it’ll temper the sweetness.
  • If you’re using heavy cream you’ll need to use a bit more than if you’re using milk or nondairy milk. The higher the fat content in the milk the more you need to use (i.e. if you’re using nonfat milk you’ll use much less!)

Storage

Store frosting in the refrigerator in an airtight container. You can also freeze the frosting; thaw in fridge. You may need to beat again with a bit more milk to create the creamy texture needed for piping. Make sure to use frosting at room temperature so it spreads smoothly.
