What Is Buttercream?
Buttercream is a soft, sweet frosting made from butter and sugar, whipped together until it is airy and spreadable. Think of it as the comfy sweater of the dessert world. It is straightforward, it is cozy, and it always makes things better. Traditional American buttercream uses butter, powdered sugar, a splash of milk or cream, and vanilla. That’s it. You can scale it up or down, color it, and flavor it in a hundred ways.

There are other types of buttercream out there, like Swiss or Italian, which use egg whites and syrup, and French, which uses egg yolks. Those are beautiful for special projects but require a little more technique. If you are starting out or just want a fast win, this classic American style is absolutely your best friend.
I use this on layer cakes, sheet cakes, cupcakes, and even sandwich cookies. It pipes cleanly and holds its shape well, especially if you give it a little chill before serving.

How to Make Buttercream
You can make Easy Buttercream Icing in about 10 minutes with a handheld mixer or stand mixer. The keys to success are soft butter, enough mixing for fluffiness, and just the right splash of liquid for silky texture. Follow these steps and you will be golden.
Ingredients
- 1 cup unsalted butter, softened to room temp
- 3.5 to 4 cups powdered sugar, sifted
- 2 to 4 tablespoons milk or heavy cream
- 2 teaspoons pure vanilla extract
- Pinch of fine salt, to taste
Directions
- Beat the butter on medium speed for 2 to 3 minutes until pale and fluffy. You want it light and creamy before you add sugar.
- Sift in half the powdered sugar and mix on low until it looks crumbly, then raise to medium and beat until smooth.
- Add the vanilla and 1 tablespoon of milk or cream, plus the salt. Mix again.
- Add the rest of the powdered sugar in two additions, alternating with small splashes of milk. Keep beating until the frosting is glossy and fluffy.
- Taste and adjust. Need more sweetness, add a little sugar. Need looser texture, add milk a teaspoon at a time. Need more structure, add a little sugar and keep mixing.
Pro tip: scrape the bowl a few times during mixing. Little butter pockets hide in the corners and can cause streaks. Also, beat longer than you think, about 2 extra minutes at the end. That final whip is what makes the frosting look bakery-light.
“I always thought bakery frosting was out of reach, but this method gave me the fluff I wanted without being too sweet. My cupcakes finally looked as good as they tasted.”
If you are making cupcakes, you will love pairing this with festive toppers like these vanilla snowman cupcakes. The frosting pipes beautifully when it is freshly whipped or after a short chill to firm it up. 
Does Buttercream Need to Be Refrigerated?
Short answer, usually no for a day or two. Traditional buttercream made with butter and sugar is stable at cool room temperature for about 1 to 2 days, especially if your kitchen is not too warm. Sugar acts as a preservative and the fat in butter helps keep the texture stable. Keep the cake or cupcakes covered so the frosting does not crust too much or pick up fridge smells.
If your home runs warm or the dessert has fillings that need chilling, then yes, pop it in the fridge. Just remember that cold buttercream firms up. Set your dessert out for 20 to 40 minutes before serving so the frosting softens and tastes creamy again. That little rest makes a huge difference.
Planning a cookie platter or holiday spread where bakes sit out for a while? Frosted cookies like classic spritz cookies do great at room temp for a day. For cakes with buttercream, try to keep them in a cooler spot away from direct sunlight.
How to Store Buttercream
Whether you made a big batch or have a cup left in the bowl, storing it right keeps the texture smooth and melty on the tongue. Here is a simple guide to keep your Easy Buttercream Icing in top shape.
Storage Tips
- Short term room temp: Keep in an airtight container for up to 2 days if your home is cool.
- Fridge: Store in an airtight container for up to 1 week. Bring to room temp and re-whip before using.
- Freezer: Freeze up to 2 to 3 months. Thaw overnight in the fridge, then bring to room temp and whip again to restore fluff.
- Re-whipping: If it looks separated or dense after storage, beat for 2 to 3 minutes. Add a teaspoon of milk if needed.
- Flavor refresh: After storage, taste and add a pinch of salt or a splash of vanilla to wake up the flavor.
For a make-ahead dessert plan, I’ll often bake layers one day, wrap and chill them, then make frosting the next day and assemble. If I need another easy sweet to sit alongside the cake, I reach for chocolate crinkle cookies. They are fast, crowd-pleasing, and store like a dream.
Why Is My Buttercream Grainy?
Grainy frosting is a common hiccup, but you can fix it. The usual culprits are dry powdered sugar, not enough mixing, cold butter, or undissolved granules. Let’s break it down in plain terms.
Troubleshooting Graininess
Check your sugar: Powdered sugar absorbs moisture in the bag, which can cause clumping. Always sift it. If it still feels sandy, your sugar might be older or lower quality. A fresh bag can make a night and day difference.
Soften the butter: If your butter is too cold, it will not blend smoothly with the sugar. You want it soft to the touch but not greasy. If you accidentally used cold butter, keep mixing longer and add a teaspoon of warm milk.
Mix more than you think: Under-mixing can leave you with texture issues. Give it an extra 2 to 3 minutes on medium speed at the end to dissolve the sugar fully and trap more air.
Add a splash of liquid: A tiny bit of milk or cream helps smooth things out. Add just a teaspoon at a time to avoid thinning too much.
Let it rest: If it still feels slightly gritty, let the bowl sit for 5 to 10 minutes, then beat again. The sugar will start to dissolve, and the texture will even out.
Once you know these fixes, your Easy Buttercream Icing will come out smooth and dreamy every bake.
Common Questions
Can I make buttercream without a mixer?
Yes, but it is a workout. Use a sturdy whisk and beat the softened butter until pale and fluffy, then gradually beat in sifted powdered sugar. The result will be slightly less airy, still delicious.
Can I color buttercream?
Absolutely. Use gel food coloring for vibrant shades without watering down the frosting. Start with a toothpick amount and build gradually.
How much frosting do I need for a cake?
About 3 to 4 cups for a two-layer 8 inch cake with moderate filling and outer coat. Double the recipe for tall layers or lots of piping.
What if my buttercream is too sweet?
Add a pinch or two of salt and a squeeze of lemon juice or a dab of cream cheese. Both balance sweetness without changing the texture too much.
Can I add flavors besides vanilla?
Yes. Try almond extract, cocoa powder, espresso powder, citrus zest, jam swirls, or caramel. Start small, taste, and adjust.
