How To Make A Less Sweet American Buttercream Frosting:

American Buttercream tends to be a quick and easy recipe that many people know how to make. However, for some people, it can be too sweet. So, here is a few tips I have for you to make this buttercream less sweet.

Lemon Juice: Adding just a bit of lemon juice to replace some of the milk can cut that sweet flavor in half.

Less Sugar: This may seem like an obvious choice, but using less sugar can help. If you are worried that your frosting may end up tasting too much like butter, you can substitute it with some shortening.

Heavy Cream: Whip up some heavy cream and add it to the frosting. This can help to dilute the sugar a bit.

Salt: Adding a pinch of salt to the buttercream can help cut the flavor, but be sure to not add too much. You want just enough to balance the flavors out.

Cream Cheese: Substitute a tablespoon or 2 of the butter with cream cheese and adjust it to your liking. Keep in mind that this can change the texture of the frosting to a much softer version.

Why Is My American Buttercream Frosting Grainy?

Grainy buttercream is a no-no! Your frosting might come out grainy if you have used the wrong kind of sugar. I make sure to use a cane sugar confectioner’s sugar because it melts faster when it’s beaten. Another reason is that you forgot to sift your sugar. When baking, it is always important to do so.

How To Fix Grainy Buttercream?

You can fix your grainy frosting by first, mixing a bit longer. This may help to break up those small lumps or pieces of sugar. Another option could be to add some more milk and let it sit overnight if you can to allow the sugar crystals to melt.

How To Make Buttercream Frosting For A Cake

You can thicken the American Buttercream by keeping it in the fridge for a bit without having to add any more of the ingredients. If you are fine with a sweeter frosting, you can add additional powdered sugar to help thicken it right away.

Does White Buttercream Need To Be Refrigerated?

No, this buttercream frosting doesn’t need to be put into the fridge. You may think that because it contains milk it would need to be. But, the powdered sugar helps stabilize the small about of milk.

Can You Freeze White Buttercream Frosting?

Yes! You can freeze your American Buttercream. Not only is this a lifesaver for when you need some frosting or a filling, but it’s also great for extending the shelf life of the recipe.

How To Store American Buttercream Frosting?

You can keep your buttercream in an airtight container or Ziploc bag for the best storage method. This recipe can be kept at room temperature, in the fridge, or freezer depending on how long you need it.
