The Perfect Crusting Buttercream

This buttercream is sweet, and I do mean sweet! (You could probably guess that by looking at the amount of confectioners’ sugar in the recipe.) However, you can always use less sugar if you don’t want the crusting buttercream to be quite as sweet. You will also notice the recipe uses a cup of shortening. I have also provided instructions on making the buttercream using half shortening and half butter.

The Perfect Crusting Buttercream Ingredients

Sugar: Yes, you are reading that amount correctly…a 2-pound bag of confectioners’ sugar is used in this recipe (approximately 7 1/2 cups). You can always use less for less sweetness.

Shortening: Shortening (hydrogenated vegetable oil) is any fat or oil that is solid at room temperature. If you have heard of or seen a big can of Crisco, that is shortening. If you don’t want to use a full cup of shortening, I did provide instructions to make crusting buttercream with half shortening and half butter.

Vanilla: If you want white frosting, use clear vanilla extract.

Milk: Start by adding the minimum amount of whole milk to the frosting mixture. You can always add more until the buttercream reaches your desired consistency.

How to Make the Perfect Crusting Buttercream

This recipe is the recipe I use when making my rose cake, my hydrangea cake, or any cake that I want the frosting to be able to hold its shape! To get it made, first, cream together the shortening and vanilla. Next, add the confectioners’ sugar one cup at a time. Finally, mix in the milk, adding more until you have reached your desired consistency, and add the pinch of salt. This makes quite a bit, but can be refrigerated quite easily.

If the buttercream will not be used right away it must be stored in the refrigerator. It will firm up quite a bit and should be allowed to come back to room temperature before piping or spreading. Depending on how long it was stored you may need to re-mix it quickly. It will last about a week in the refrigerator.

How to Make Crusting Buttercream with Shortening and Butter

If you are using half shortening and have butter, the method to make the buttercream is a little different. First, add the butter (make sure it is room temperature) and the shortening to the bowl of a stand mixer. Next, pour all of the confectioners’ sugar on top. Then, add the vanilla, milk, and salt. Start mixing on low; then, turn the mixer to medium-high and mix for 2-4 minutes.
