Frequently Asked Questions
Buttercream should have a slightly stiff but creamy texture, and shouldn’t melt at room temperature unless it’s more hot or humid than normal. Try to store the finished cake in a cool, dry place while you’re serving it, then refrigerate.
If you have a cake frosted with buttercream, you can refrigerate it for about a week. You can also make the cake ahead of time and freeze it, already frosted with the buttercream. Just put the cake in the freezer until it’s frozen, about an hour, then wrap it in plastic wrap (so the buttercream stays in place).
Then you can just defrost in the refrigerator, and finally bring the cake back to room temperature before serving. When a cake is cold, it might be mistaken for stale, so make sure you take it out of the refrigerator for about an hour to let it warm up before slicing into it.
If your buttercream didn’t stiffen up like it was supposed to, you can add powdered sugar one tablespoon or two at a time. Don’t add this too fast, because you can go in the opposite direction if you add too much powdered sugar. You can also add a tablespoon of cornstarch to help thicken it.
If it’s not runny and it’s just too soft, refrigerate the frosting for 30 minutes to an hour to see if it helps the texture, because the butter might have melted too much from over-mixing or if the temperature in the kitchen is too warm.
If your frosting turned out too thick, you can thin it out by adding a tablespoon of cream at a time until it reaches the desired consistency. Be careful not to add too much, or the frosting might get too thin.

Tips for Making Classic Buttercream Frosting
- You can use salted or unsalted butter to make this buttercream recipe, but it’s best to use unsalted butter so you can control the amount of salt going into the recipe.
- If you’re frosting a cake or cupcakes, make sure that the buttercream frosting is the same temperature, or it will pull crumbs off of your cupcakes and look messy.
- If your frosting turns out too sweet, add a pinch of salt or a teaspoon of lemon juice to balance out the flavor.

- It’s easy to make this buttercream frosting recipe in the stand mixer with a paddle attachment, but you can use an electric hand mixer if that’s what you have.
- Make sure you set the stand mixer for low speed while you’re adding the powdered sugar, or the sugar will fly out of the top when you’re trying to mix it.
