Too-Cold Butter

When you are mixing the ingredients for your buttercream, it is important that you make sure your butter is at room temperature and is not cold butter.

You should have softened butter because otherwise you will have a grainy texture.

It needs to be at room temperature butter because it will be softer and easier to mix into the other ingredients.

If it is too cold, it will only make the mixture quite clumpy and contain lots of grains.

Nobody wants lumpy frosting.

Melted Butter

However, you need to make sure that your butter is not completely melted, but also hasn’t come straight out of the fridge.

You can either leave it out like you’re defrosting something for about an hour, or you can use the microwave slightly for a short period of time to make it room temperature. 

You need to have softened butter not melted.

Using Margarine

Even Though lots of people love margarine, it is definitely not the best type of butter for baking.

It also means that it is not the best type of butter to use for your buttercream as well.

There is actually more water and less fat in this butter which means you won’t be able to get that really creamy texture which is what everyone wants for their buttercream with no grainy texture.

The butter is one of the most important ingredients in the buttercream which is why it needs to be perfect and not leave your buttercream grainy. 

Powdered Sugar

Purchase Powdered sugar is a type of sugar that contains a smaller amount of sucrose than regular sugar.

While it is made from powdered sugar, it is not the same sugar as cane sugar or sugar beets.

It can be used in recipes that call for regular sugar.

The sugar is very fine and soft, but that definitely does not mean that it won’t create clumps.

When you start using sifted powdered sugar, it will not give you the right consistency for your buttercream.

Unsifted Powdered Sugar

When the sugar is unsifted, it will have little lumps in it which will become part of your buttercream which you will want to avoid and the gritty buttercream. 

Therefore, use sifted powdered sugar. avoid grainy buttercream!
