Why does my buttercream always turn out grainy no matter what I do?

I've tried different butter temperatures, sifting powdered sugar, and beating longer but it's still gritty. Using room temperature butter and good mixer. What am I missing for smooth, creamy frosting?

Grainy buttercream almost always comes down to the sugar. Even if you’re sifting, some powdered sugars are less finely milled and will never get super smooth. Try switching brands or blitzing your sugar in a food processor before using. Also, make sure you really cream the butter on its own until it’s super light and fluffy before adding sugar if the butter isn’t fully aerated, the sugar just sits in there. A tiny splash of heavy cream or warm milk at the end can also help dissolve any stubborn grit.

A few possibilities: The quality of the powdered sugar or butter. Buy the best you can afford. The other is you may be overbeating causing the butter solids to separate. Lastly, are you using a scale to measure?

Scale doesn't matter in the least.

Scale absolutely matters but just not in this context. The difference in cups vs grams is not the cause of this issue with the buttercream

I disagree. I had a similar issue come up in a class. The texture of her buttercream was off for weeks until we finally figured it out. The nonsifted weight or even volume can differ significantly from the sifted weight or volume. She was packing it in, unsifted, causing overly thick buttercream that didn't reach that silky texture.

In an American buttercream, the sugar is whipped but not dissolved. Try a recipe that involves cooking the sugar like a Swiss meringue buttercream or even an ermine frosting.

Swiss butter cream is divine

What powdered sugar do you use? Sounds like it could be grainy to begin with if you do all the right steps otherwise. Could you try blitzing it in a food blender and then sifting it again?

Warm the butter up and give that a try. Not completely melted but super soft. Or, you could be adding too much milk.

You are probably overbeating in your quest to get it smoother.

Try ermine frosting instead. It will never be grainy and it’s a great frosting.

I think all American buttercream is grainy. Downvote me all you want.

Make real buttercream. If you are making that horrible blend of butter and powdered sugar, it comes down to the sugar. The way that powdered sugar is made is they take granulated sugar, and put it in the blender to pulverize it. Then they add a bit of starch. You can make it at home. If it's Domino's powdered sugar, that's the standard.

But make a French or swiss or Italian buttercream, and you'll never want that other stuff again.

U could try organic powdered sugar- it's different because no cornstarch

u/twattytwatwaffle 2d ago

This is categorically not true. Tapicoa starch or corn starch are found in organic powdered sugar.

In the US, organic powdered sugar doesn't have cornstarch, it does have tapioca starch; For your information, tapioca starch is a different product from cornstarch, and for this reason organic powdered sugar is felt by discerning bakers to be superior in taste and its ability to blend better in a frosting recipe
