Swiss Meringue vs. American Buttercream: Which Gourmet Frosting Is Best for Cookies?

Recipe testing: Tested across five iterative batches to ensure the butter-to-meringue ratio holds a stable piping consistency without splitting.

There are two buttercreams you’ll see on most gourmet cookies. One is made in five minutes with butter and powdered sugar. The other involves a thermometer, a pot of simmering water, and a good 30 minutes. Both are called buttercream, both pipe a beautiful swirl, and they taste and behave very differently.

This guide compares American buttercream and Swiss meringue buttercream (SMBC) specifically for cookies: how each tastes and feels, how they hold up on a cookie, when each is the better choice, and how to make a cookie-sized batch of Swiss meringue buttercream. This article is part of our pillar guide to Gourmet Frostings, Glazes, and Cream Cheese Icing, where American buttercream is one of the four frosting families.

💡 Quick take: Choose American buttercream when you want something fast, sturdy, and very sweet that holds a tall, thick swirl and crusts slightly on top. Choose Swiss meringue buttercream when you want a silky, buttery, much less sweet frosting that stays soft and doesn’t crust — and you don’t mind the extra steps.

What Is American Buttercream?

American buttercream is the simplest buttercream: butter beaten until light, then combined with sifted powdered sugar, a little liquid, vanilla, and salt. Nothing is cooked, and there are no eggs.

As our pillar guide explains, it’s sweeter and denser than meringue-based buttercreams, which makes it ideal for the thick, swirled applications common on Crumbl-style cookies. Because it’s mostly butter and sugar, it forms a light crust as it sits, which helps frosted cookies stack or travel more easily.

What Is Swiss Meringue Buttercream?

Swiss meringue buttercream starts with a meringue. Egg whites and granulated sugar are whisked together over a pot of simmering water until they reach 160°F (71°C), which dissolves the sugar and heats the egg whites enough to be safe to eat. The mixture is then whipped to a stiff, glossy meringue, cooled, and beaten with soft butter a little at a time until it turns smooth and silky.

The result is a frosting that’s lighter in color, much less sweet, and noticeably more buttery than American buttercream. It doesn’t form a crust, and it keeps a soft, creamy texture.

How They Perform on Cookies

Sweetness

Cookies are already sweet, so the frosting sets the balance. American buttercream on a sugar cookie is a very sweet pairing; SMBC lets the cookie’s flavor come through. If your cookie is rich or chocolatey, SMBC often tastes more balanced.

Texture and mouthfeel

American buttercream is dense and slightly sandy; many people love that nostalgic, bakery-case texture. SMBC is silky and melts on the tongue. On a thick, soft cookie, either works, but SMBC feels lighter.

Handling and piping

Both pipe well with a large star tip such as 1M or 2D. American buttercream gives bolder, thicker shapes. SMBC gives smoother edges and more refined definition, but it’s softer, so piped swirls may be slightly less tall.

Stability and heat

Both are butter-based, so neither is heat-proof. Swiss meringue buttercream can sit covered at room temperature for a day or two (Sally’s Baking Addiction suggests 1–2 days, then refrigeration), while American buttercream’s crust helps it hold up in transit. In a hot kitchen or at an outdoor party, keep both in the shade or the refrigerator. For truly hot climates, see our guide to Italian meringue buttercream in this cluster.

Crusting

American buttercream crusts lightly; SMBC doesn’t. For stacking frosted cookies in a box, a crust is an advantage. For soft, melt-in-the-mouth cookies, no crust is a plus.

Food safety

American buttercream has no eggs. SMBC does, though heating the whites to 160°F (71°C) makes them safe to eat. If you serve people who need to avoid eggs entirely, or you can’t use a thermometer, choose American buttercream.

Recipe 1: American Buttercream for Cookies

This is the base recipe for a thick, swirlable frosting. It yields about 2 cups, enough for 10 large cookies.

Ingredients

• 1 cup (227 g) unsalted butter, softened but cool
• 3 cups (360 g) powdered sugar, sifted
• 1–2 tablespoons heavy cream or milk
• 1 teaspoon vanilla extract
• ¼ teaspoon fine salt

Instructions

1. Beat the butter on medium for 2 minutes until pale and creamy.
2. Add the sifted powdered sugar a cup at a time on low, then add the vanilla and salt.
3. Add 1 tablespoon of cream and beat on medium-high for 3–4 minutes, until light and fluffy. Add the second tablespoon only if needed.
4. Pipe or spread on completely cooled cookies.

Recipe 2: Swiss Meringue Buttercream for Cookies

This half-batch recipe uses the same ratio as a classic SMBC and yields about 2½ cups, enough for 10 large cookies. Weigh the ingredients and use a thermometer.

Prep time: 40 minutes

Ingredients

• 3 large egg whites (about 90 g), fresh, at room temperature
• ¾ cup (150 g) granulated sugar
• 1 cup (227 g) unsalted butter, softened but cool (about 65–68°F / 18–20°C), cut into tablespoon-size pieces
• 1½ teaspoons vanilla extract
• ¼ teaspoon fine salt

Instructions

1. Prepare the double boiler. Fill a saucepan with about 2 inches (5 cm) of water and bring to a gentle simmer. The bottom of your mixing bowl must not touch the water.
2. Heat the whites and sugar. In the heatproof bowl of your stand mixer, whisk the egg whites and sugar together. Set the bowl over the simmering water and whisk constantly until the mixture reaches 160°F (71°C) and the sugar has fully dissolved (rub a drop between your fingers: it should feel smooth, not gritty). This takes about 3–4 minutes.
3. Whip to stiff peaks. Transfer the bowl to the mixer fitted with the whisk attachment. Whip on medium-high for 8–10 minutes, until the meringue is thick, glossy, and the bowl feels completely cool to the touch. This step is critical: warm meringue will melt the butter.
4. Switch to the paddle. Swap to the paddle attachment and beat on medium-low.
5. Add the butter. Add the butter one piece at a time, waiting until each is incorporated before adding the next. The mixture may look soupy or curdled partway through; keep beating and it will come together.
6. Finish. Add the vanilla and salt and beat on low for 2–3 minutes to push out air bubbles and make it silky.
7. Pipe. Use immediately on cooled cookies, or cover and keep as directed below.

Tips for Success

• Use fresh egg whites. Fresh whites whip better than carton whites, and a trace of yolk or grease can stop them from whipping at all. Wipe the bowl and whisk with a little white vinegar or lemon juice first.
• Check the temperature. Heat to 160°F (71°C) for safety and sugar dissolving. Don’t overheat or the whites will scramble.
• Cool the meringue completely. If the bowl still feels warm, wait. Most failed batches are a temperature problem.
• Keep the butter soft but cool. Butter that’s too warm makes soupy frosting; too cold makes lumpy frosting.

Troubleshooting

Problem	Likely cause	Fix
SMBC is soupy or runny	Meringue or butter too warm	Chill the bowl 10–15 minutes, then re-whip
SMBC looks curdled or split	Butter too cold, or mixture too cool	Warm the bowl briefly with a warm towel or hair-dryer, then beat on medium
SMBC won’t whip to peaks	Egg yolk or grease in the whites, or whites not fully heated	Start over with clean equipment and fresh whites
SMBC has air bubbles	Overwhipped after the butter went in	Beat on the lowest speed with the paddle for a few minutes
SMBC tastes eggy	Whites not fully dissolved or too much beating	Use fresh eggs and a bit more vanilla; add a pinch of salt
American buttercream is grainy	Sugar unsifted or butter too cold	Sift; soften butter slightly; beat 3–4 minutes
American buttercream is too sweet	Standard recipe	Add a pinch of salt, use browned butter, or switch to SMBC
Buttercream melts on the cookie	Cookies still warm	Frost only completely cooled cookies

Storing Each Frosting

• American buttercream: Refrigerate in an airtight container for up to a week or freeze up to 2 months. Bring to cool room temperature and re-whip before using.
• Swiss meringue buttercream: Keep covered at room temperature for 1–2 days, refrigerate for up to 5 days, or freeze for up to 3 months. If it looks broken after chilling, let it come to room temperature and re-whip on low until smooth.
• Frosted cookies: Store in a single layer in an airtight container. American buttercream’s crust helps with stacking; SMBC-frosted cookies need more careful handling.
