Ingredients for buttercream recipe with egg white
Five ingredients for buttercream that stays light, stable, and perfect for decorating.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Egg Whites 🥚 | 5 whole | Room temperature for best volume |
| Unsalted Butter 🧈 | 1 lb | Cold, cubed for easier folding |
| Powdered Sugar 🍚 | 4 cups | Sifted for smooth texture |
| Vanilla Extract 🌿 | 1 tbsp | Pure vanilla for best flavor |
| Fine Sea Salt 🧂 | ¼ tsp | Balances sweetness |
The egg whites are your secret weapon—room temperature makes all the difference. Whole eggs can be separated using a bowl and whisk, but I always grab a separating cone from the kitchen store for clean results. Butter? European-style (like Plugrá) has higher fat content, which gives you a richer frosting. If you're using regular butter, make sure it's cold and cubed—room temp butter melts too fast when folding. Powdered sugar? Domino or Culinary Art are my go-tos—they're sifted and dissolve smoothly. Skip the generic store brands unless you're feeling adventurous.
No vanilla extract? Vanilla bean paste works too, or even almond extract at half the amount for a different twist. Running low on butter? Vegan butter (like Miyoko's) keeps this recipe vegetarian-friendly. The salt is non-negotiable—it cuts through the sweetness and balances the richness. If you're using unsalted butter (which you should), this tiny pinch keeps things perfect. Pro tip: Sift the powdered sugar before measuring—clumps make your frosting grainy. And if you're worried about egg safety, pasteurized egg whites work too.
This frosting keeps beautifully—5 days in the fridge, 3 months in the freezer. For freezing, portion into ziplock bags and squeeze out air before sealing. Thaw overnight in the fridge, then re-whip briefly if it gets too firm. I always make extra—it's perfect for filling between cake layers or piping decorations. If it gets too thick, microwave 10 seconds to soften before re-whipping. And trust me, it's worth the extra minute to whip those egg whites to stiff peaks—your cakes will thank you.

Step-by-step instructions for light and stable egg white buttercream
Here's how to make the perfect fluffy, pipeable frosting that stays put.
🍳 Step 1: Whip the Egg Whites to Stiff Peaks
In a clean, grease-free metal bowl, combine the 5 whole large egg whites and 0.25 teaspoon fine sea salt. Use a stand mixer fitted with the whisk attachment and beat on medium speed until soft peaks form. This usually takes about 2-3 minutes—you'll see the whites thicken and hold their shape when you lift the whisk.
Here's the thing—don't rush this step. The egg whites need to be fully whipped to create that light, airy structure that prevents weeping later. When you lift the whisk, the peak should stand straight up for 10 seconds before slowly melting back down. This is your signal that they're ready for the next step.
👨🍳 Step 2: Gradually Add Powdered Sugar
With the mixer still running on medium speed, begin adding the 4 cups powdered sugar about ½ cup at a time. After each addition, let the sugar fully incorporate before adding more. This gradual approach prevents deflating the egg whites and ensures a smooth, lump-free frosting.
I find it helps to sift the powdered sugar first—this prevents clumping and makes it easier to incorporate evenly. Keep mixing until all the sugar is combined and the mixture becomes thick and glossy. It should hold its shape when you lift a spoonful, but still be pipeable. If it's too thick, you can add 1-2 teaspoons of water to loosen it slightly.
🥘 Step 3: Incorporate the Cold Butter
Switch your mixer to low speed and begin adding the 1 lb cold, cubed unsalted butter one cube at a time. Let each cube fully incorporate before adding the next—this prevents the butter from melting and creating a greasy texture. The butter should blend smoothly into the mixture, creating a creamy, fluffy consistency.
This is where patience pays off. If you add the butter too quickly, you'll end up with a greasy, soupy mess. Take your time, and you'll get that perfect light texture. The frosting should now be thick but still pipeable. If it's too soft, chill it for 15-20 minutes before proceeding.
🍽️ Step 4: Add Vanilla and Final Adjustments
Add the 1 tablespoon vanilla extract and mix on low speed until fully combined. Taste and adjust the sweetness if needed—you can add more powdered sugar if desired, but remember that the buttercream is already quite sweet. The vanilla should be evenly distributed throughout the frosting, giving it that classic flavor.
For best results, cover the bowl with plastic wrap pressed directly against the surface of the frosting. This prevents a skin from forming and keeps it smooth. Let it sit at room temperature for 10 minutes before using. This resting time allows the flavors to meld and the texture to stabilize.
Pro Tips For Making Buttercream Recipe With Egg White
- Whip Egg Whites Cold: Take your egg whites straight from the fridge—room temperature is the enemy here. Cold whites whip faster and hold their volume better, so resist the urge to let them sit out. I learned this the hard way when my buttercream turned into a sad, flat mess because the whites warmed up mid-whipping.
- Soften Butter Slowly: Don’t nuke your butter in the microwave—it’ll turn greasy and ruin your emulsion. Instead, cut it into small cubes and let it sit at room temp for 30-45 minutes, or warm it gently in a bowl of hot water (not boiling). You want it soft enough to beat easily, not melted into a puddle.
- Salt Before Mixing: Toss that pinch of fine sea salt into your powdered sugar before combining with anything else. It dissolves better and distributes evenly, so every bite gets a balanced flavor. I used to add it later and ended up with clumps—now I just mix it in upfront and forget about it.
- Use a Stand Mixer: Hand-whipping egg whites for buttercream is a workout that doesn’t pay off. A stand mixer with the whisk attachment (on medium-high) does the job in minutes without overworking the proteins. If you’re short on time, this is the non-negotiable upgrade—your arms will thank you later.
Common mistakes when making this dish
Overwhipped Egg Whites
I’ve seen this happen more times than I can count—egg whites whipped to stiff peaks and then overmixed into a dry, grainy mess. When your buttercream starts looking like stiff meringue instead of smooth frosting, you’ve gone too far. The key is to stop whipping the moment the egg whites form firm peaks that hold their shape but still have a slight sheen. Overwhipping introduces too much air, which can make your frosting unstable and prone to cracking when piped. 💫
Room-Temp Butter
Nothing ruins a perfect buttercream faster than room-temperature butter. When butter melts too quickly during folding, it creates a greasy, soupy texture that’s impossible to pipe. Always use cold, cubed butter straight from the fridge. If your kitchen is warm, chill the cubes on a plate for 10-15 minutes before starting. Pro tip: I like to cut my butter into ½-inch cubes—this gives you better control when adding them gradually.
Skipping the Resting Time
This is a big one—skipping the 10-minute rest after mixing can lead to a frosting that’s either too soft or too stiff. The resting period lets the buttercream stabilize, allowing flavors to meld and the texture to even out. If you’re in a rush, at least let it sit for 5 minutes before piping. I’ve learned the hard way that rushing this step often results in frosting that slides off cakes or collapses under its own weight.
Adding Butter Too Fast
Dumping all the butter into your mixer at once is a recipe for disaster—literally. The butter will melt too quickly, turning your frosting into a greasy, lumpy mess. Instead, add the butter one cube at a time, letting each one fully incorporate before moving to the next. If your frosting starts looking curdled or grainy, stop immediately, chill it for 15 minutes, and try again. Patience here is everything.
Not Sifting Powdered Sugar
Clumpy powdered sugar is the silent killer of smooth buttercream. If you skip sifting, you’ll end up with grainy texture that’s impossible to pipe cleanly. Always sift your powdered sugar before measuring—it dissolves more evenly and prevents lumps. I like to sift mine directly into the bowl while mixing, which helps distribute it smoothly. For extra insurance, I’ll give the bowl a quick tap on the counter to settle any remaining clumps before whipping.
Ignoring the Salt
That ¼ teaspoon of salt might seem insignificant, but it’s what balances the sweetness and enhances the flavor of the buttercream. Skipping it can make your frosting taste flat or overly sugary. The salt also helps stabilize the egg whites during whipping. Trust me, your taste buds (and your cake) will thank you for this tiny but mighty ingredient. 🧂

Frequently asked questions
Why use egg whites in buttercream?
Egg whites add lightness and stability without extra moisture. When whipped to stiff peaks, they create air pockets that make the frosting fluffier while preventing weeping or soggy layers. This technique is perfect for tiered cakes or intricate piping designs that need to hold their shape.
Can I substitute the egg whites with something else?
For a similar light texture, you could try aquafaba (chickpea brine) at a 1:1 ratio, but the flavor will differ slightly. Traditional buttercream uses just butter and powdered sugar—egg whites are what give this version its signature stability. If you're avoiding eggs entirely, consider meringue buttercream instead.
How do I fix buttercream that's too thick or too thin?
For thick buttercream, add 1 teaspoon of water at a time and mix gently. If it's too thin, chill for 15-20 minutes to firm up, then re-whip briefly. Never microwave—it can melt the butter unevenly. For best results, keep your kitchen cool while working.
Will this frosting work for warm climates?
Yes, but store it in an airtight container in the fridge between uses. In hot weather, the butter can soften faster, so chill the frosting for 10 minutes before piping. For extra stability, add 1 teaspoon cornstarch to the powdered sugar mixture. This frosting holds up well in 75°F+ temperatures if properly chilled.
Can I color this buttercream with food dye?
Use gel-based food coloring for vibrant hues without altering the texture. Add the dye gradually while mixing on low speed. For pastel shades, start with ½ teaspoon and adjust. Liquid dye can make the frosting too thin—always test a small batch first. This frosting takes color beautifully for cakes and cupcakes!
