If you are wondering how to make buttercream less sweet, you do not have to throw the bowl away or start over. A little salt, a stronger flavor, or a careful change to the balance can make the sweetness feel gentler without leaving you with loose frosting.
The key is to change one thing at a time. Powdered sugar is what helps American buttercream hold its shape, so taking a lot of it out at once changes the texture as much as the taste.
Quick Fixes: What to Add and What to Expect
| Fix | How much to add | What it does to taste and texture |
|---|---|---|
| Fine salt | A tiny pinch (less than ⅛ tsp) | Balances sweetness. Too much tastes salty. |
| Vanilla extract | ¼ tsp (about 1 g) at a time | Adds aroma and rounds out the flavor, with little change in texture. |
| Cream cheese | 30 g (about 2 tbsp) at a time | Adds tang. Softens the frosting, so chill if needed. |
| Cocoa powder | 1 tbsp (5 to 6 g) at a time | Adds a little bitterness and thickens. Sift it first. |
| Citrus zest or lemon juice | ½ tsp zest, or ¼ tsp juice at a time | Adds brightness. Too much juice loosens the frosting. |
| Unsalted butter | 15 g (1 tbsp) at a time | Dilutes the sweetness slightly and adds richness. Softens when warm. |
These amounts are starting points for roughly 2 cups of frosting. Add a little, mix well, then taste before you add more.
Why American Buttercream Tastes So Sweet
American buttercream is made by beating butter with powdered sugar, then adding vanilla and sometimes a little milk or cream. Most recipes use far more sugar than butter, because powdered sugar does more than sweeten. It thickens the frosting and helps it hold swirls and sharp edges.
All that sugar is useful for a firm, easy-to-pipe frosting, but it can hide the flavor of the butter. Powdered sugar also contains a small amount of starch to keep it free-flowing, which can add a faintly dry, powdery feeling when there is a lot of it.
So the goal is not to make frosting that is not sweet at all. It is to balance the sweetness with salt, aroma or tang while keeping enough structure for the job.
How to Make Buttercream Less Sweet: 7 Easy Fixes
1. Add a Small Pinch of Salt
Start here, because it is quick and adds no moisture. Use fine salt, add only a tiny pinch, beat for 20 to 30 seconds and taste. If your frosting was made with salted butter, start with even less.
2. Build Up the Vanilla Flavor
Vanilla makes frosting smell fuller, so the sweetness feels less flat. Add ¼ teaspoon (about 1 g) at a time, using pure vanilla extract or vanilla bean paste. Do not pour in a big splash, because the extra liquid can loosen the frosting.
3. Add a Little Cream Cheese for Tang
Beat in softened cream cheese in small portions, starting with 30 g (about 2 tablespoons) for every 2 cups of frosting. The gentle tang balances the sugar well. The trade-off is that the frosting gets softer and must be kept in the refrigerator. Chill it briefly before piping if it feels loose.
4. Add Unsweetened Cocoa or Dark Chocolate
If chocolate suits your cake, sift in 5 to 6 g (about 1 tablespoon) of unsweetened cocoa powder, mix and taste before adding more. Cocoa brings a pleasant bitter note and soaks up a little moisture. For a richer result, use melted dark chocolate that has cooled completely. Warm chocolate melts the butter and changes the texture.
If you want a frosting that is chocolate from the start, see our chocolate frosting recipe.
5. Use Citrus Zest or a Few Drops of Juice
Lemon or orange zest adds a strong, fresh aroma with almost no liquid. Start with ½ teaspoon of finely grated zest per 2 cups of frosting. If you use lemon juice, add only ¼ teaspoon (about 1 g) at a time and stop as soon as the flavor brightens.
6. Beat In a Little Extra Butter
If the frosting is very sweet and also feels stiff, beat in 15 g (1 tablespoon) of softened unsalted butter at a time. This lowers the share of sugar a little. It will not change the sweetness dramatically, and butter that is too warm can turn the frosting greasy or soft, so go slowly.
7. Choose a Different Frosting Next Time
If you always find American buttercream too sweet, the easiest long-term answer is a frosting that does not rely on so much powdered sugar. Swiss meringue buttercream and ermine frosting are good places to start. There is a comparison further down.
How to Fix Buttercream That Is Already Too Sweet
First decide how far off it is. If it is only a little too sweet, add a pinch of salt or a little vanilla, mix well and taste again. If the flavor still feels flat, a small amount of cream cheese, cocoa or citrus zest will give it the contrast it needs.
If it tastes intensely sugary, make a second small batch with less sugar and combine the two a little at a time. You cannot take sugar out of a finished bowl, so this is the more reliable route. Add the new batch in portions and stop when both the taste and the texture are right.
Do not use every fix at once. Too much salt, lemon, cocoa or cream cheese creates a new problem, and you will not know which one helped.
How to Make Buttercream Less Sweet Without Making It Runny
Protect the structure while you adjust the taste. Keep the butter soft but not shiny or melted. Around 65–68°F (18–20°C) is a useful working range for most American buttercream. In a warm kitchen, make small additions and stop to check the texture.
Reach for dry additions first: fine salt, sifted cocoa or citrus zest. Add extracts and juice a few drops at a time. Cream cheese and extra butter both soften the frosting, so use small portions and chill the bowl for 10 to 15 minutes if it turns loose.
If the frosting is already loose, do not keep adding liquid to improve the flavor. Follow our guide on how to fix runny buttercream first, then come back to the taste. And if it turns gritty after you change the ingredients, why is my buttercream grainy will help you work out whether the cause is sugar, temperature or mixing.
Less Sweet Types of Frosting: A Quick Comparison
| Frosting | Sweetness | Texture and best use | Keep in mind |
|---|---|---|---|
| Swiss meringue buttercream | Usually tastes less sugary | Silky and smooth. Good for neat finishes and piping. | Egg whites and sugar are heated together, and it needs careful mixing. |
| Ermine frosting | Mild and balanced | Light, fluffy and spreadable. Lovely with chocolate or red velvet cake. | The cooked milk-and-flour base must cool fully before the butter goes in. |
| Whipped cream frosting | Can be only lightly sweetened | Airy and delicate. Best served chilled. | Not sturdy in warm rooms and not suited to detailed piping. |
| Cream cheese frosting | Tangy, so it tastes balanced | Creamy and soft. Classic on carrot cake and red velvet. | Loosens if overmixed or warm. Keep it refrigerated. |
These frostings are made differently from American buttercream, so follow a recipe written for each one. A tangy cream cheese frosting is a natural match for our carrot cake and red velvet cake.
What Not to Do When Reducing Sweetness
- Do not remove most of the powdered sugar at once. It is part of the structure. Cutting it by half can leave buttercream greasy, soft and unable to hold a piped shape.
- Do not pour in lots of milk, cream or juice. Liquid thins the frosting long before it changes the flavor enough.
- Do not add salt by the spoonful. A tiny pinch can balance a whole bowl. Too much makes it taste harsh.
- Do not use warm butter or warm chocolate. Warm fat melts the butter and turns the frosting slack. Let melted chocolate cool until it no longer feels warm.
- Do not expect one frosting to do every job. Whipped cream tastes less sweet, but it will not hold the sharp edges that American buttercream does.
If you plan to color the frosting, adjust the flavor and texture first, then follow the tips in how to color buttercream.
A Less-Sweet Vanilla Buttercream to Try
If you would rather start with a frosting that is balanced from the first spoonful, this small batch uses far less powdered sugar than a classic American buttercream, with a little cream cheese for tang. It is best for spreading and simple swirls.

Ingredients
Equipment
Method
- Beat the softened butter on medium speed for 2 to 3 minutes, scraping down the bowl once, until lighter in color and creamy.
- Add the sifted powdered sugar in three additions, mixing on low speed after each one, then beat until combined.
- Add the cream cheese, vanilla and salt. Beat on medium speed for about 1 minute, just until smooth. Do not overbeat, because cream cheese loosens with long mixing.
- Check the texture. If the frosting is too stiff to spread, add the cream 1 teaspoon at a time. If it is already soft, leave the cream out.
- Taste the frosting. For more balance, add a tiny extra pinch of salt or a few drops of vanilla, mixing and tasting between additions.
- If the frosting feels too soft, refrigerate it for 10 to 15 minutes, then stir or beat briefly until spreadable. Use on a completely cooled cake or cupcakes.
Notes
Frequently Asked Questions
Can I just use less powdered sugar in buttercream?
Yes, but reduce it a little, not a lot. Less sugar means softer frosting that holds its shape less well. If you want a much less sweet frosting, a different style will give you a better result.
Does salt make buttercream taste less sweet?
A tiny amount balances the sweetness and brings out the butter and vanilla. It does not remove any sugar, so add it gradually and taste between additions.
Will cream cheese make buttercream less sweet?
It makes the flavor tangier and more balanced. Start with a small amount of softened cream cheese, then check that the frosting is still firm enough for what you want to do with it.
Can I make buttercream less sweet after adding food coloring?
Yes. Use small additions and mix thoroughly. Keep in mind that extra ingredients such as cocoa or cream cheese can change the shade slightly.
Why did my buttercream become runny after I reduced the sugar?
Powdered sugar gives the frosting its body. Take out too much and the butter and liquid have nothing to hold them up. Chill the frosting for 10 to 15 minutes and beat it briefly, then add a little sugar back if it is still loose.
Which frosting is the least sweet?
There is no single winner. Ermine frosting is often described as mild and balanced, and Swiss meringue buttercream usually tastes less sugary than American buttercream. Whipped cream can be sweetened very lightly, but it is more delicate.
How should I store less-sweet buttercream?
Keep it covered in the refrigerator. Any frosting that contains cream cheese, whipped cream or a cooked milk base must stay chilled and should not sit out for long. Before using it again, let it soften at cool room temperature and beat it briefly until smooth.
The Takeaway
Buttercream that is too sweet is easy to rescue. Start with a pinch of salt, add a little vanilla or tang, and change one thing at a time so the frosting keeps its shape. If you still find it too sweet, try a different style of frosting next time.
