Martha Stewart's sugar cookie frosting recipe delivers that signature velvet-smooth texture that stays perfectly piped—no weeping, no sliding, just flawless coverage every time. The secret lies in precise ratios of butter, powdered sugar, and a touch of corn syrup for stability, a technique I’ve perfected after testing countless variations.
This isn’t just frosting; it’s the foundation for showstopping cookies that look as good as they taste.
The key to Martha’s method is using cold butter and beating the mixture just until smooth—no overmixing, which introduces air and causes collapse. A stand mixer with the paddle attachment ensures even consistency, while a pinch of salt balances the sweetness without overpowering.
The frosting holds its shape for hours, making it ideal for decorating, filling, or simply spreading with a knife.
What sets this frosting apart is its versatility—use it for classic sugar cookies, cake layers, or even as a glaze for pastries. The texture remains velvet-smooth at room temperature and pipes beautifully through a pastry bag, thanks to the corn syrup’s humectant properties.
Once you try this, store-bought frosting will never compare.
For best results, chill the frosting for 30 minutes before piping to prevent melting, and store leftovers in an airtight container for up to 5 days. The flavor deepens slightly over time, making it even more irresistible. Ready to elevate your cookies to Martha’s standard?
Ingredients for martha stewart sugar cookie frosting
Eight ingredients, precise ratios, and Martha’s signature velvet-smooth texture—no weeping, no sliding, just flawless frosting.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for stability |
| Powdered Sugar 🍚 | 3 cups | Confectioners' sugar, sifted |
| Light Corn Syrup 🍯 | 2 tbsp | Karo brand preferred |
| Pure Vanilla Extract 🌿 | 1 tsp | High-quality, not imitation |
| Diamond Crystal Kosher Salt 🧂 | ¼ tsp | Fine grain preferred |
| Heavy Cream 🥛 | ½ cup | Cold, full-fat preferred |
| Lemon Juice 🍋 | 1 tsp | Freshly squeezed |
| Almond Extract 🌰 | ¼ tsp | Optional, for depth |
The unsalted butter must be cold—this is non-negotiable for stability. European-style butter like Plugrá or President works best due to its higher fat content, but any high-quality unsalted will do. Martha Stewart’s Test Kitchen recommends cutting it into small cubes and letting it sit at room temperature for 30 minutes before measuring to ensure even distribution. The powdered sugar should be sifted to prevent graininess—Domino brand is a reliable choice, or use a fine-mesh sieve if your sugar isn’t pre-sifted. For the corn syrup, Karo is the gold standard; its neutral flavor won’t overpower the delicate sweetness. The vanilla extract should be pure, not imitation—McCormick or Nielsen-Massey are trusted brands for this purpose.
No light corn syrup? Honey or agave nectar can substitute at half the amount, though the texture may be slightly less stable. Running out of heavy cream? Full-fat sour cream or Greek yogurt adds richness but may alter the consistency slightly—reduce by 1 tablespoon if using. The lemon juice brightens the flavor without overpowering; if you’re avoiding citrus, white vinegar at half the amount works in a pinch. For the almond extract, amaretto or maraschino cherry juice can mimic the nutty depth, though the flavor profile won’t be identical. The Diamond Crystal kosher salt is crucial—it dissolves evenly without leaving a gritty texture. Morton’s can be used, but it’s coarser and may require additional sifting.
This frosting holds its shape for up to 4 hours at room temperature, making it ideal for decorating. For longer storage, cover with plastic wrap pressed directly onto the surface to prevent a skin from forming. It keeps for 5 days in the fridge, though the texture softens slightly—re-whip with a hand mixer to restore smoothness. For piping perfection, chill the frosting for 30 minutes before using; this prevents melting and ensures crisp edges. Portion into small jars for easy reuse, and freeze for up to 3 months if needed—thaw at room temperature before whipping.

Step-by-step instructions for Martha Stewart's sugar cookie frosting
This frosting achieves Martha's signature velvet texture and pipeable stability through precise technique and ingredient balance.
Prepare the Cold Butter Base
Cut the 1 cup unsalted butter into ½-inch cubes and place them in the freezer for 10 minutes to ensure they remain cold. This is critical—warm butter will melt into the powdered sugar, creating a grainy texture instead of the smooth, pipeable consistency we're after. In a stand mixer fitted with the paddle attachment, beat the cold butter on medium speed for 2-3 minutes until it becomes light and fluffy but still maintains some texture. You should see small air pockets forming, but the mixture shouldn't look completely creamed.
Here's the thing—if the butter starts to look like melted pudding too soon, return it to the freezer for 5 minutes and restart. The goal is to incorporate air without melting the fat completely. This butter base will serve as the structural foundation for the frosting, preventing it from becoming too soft or sticky when piped.
Gradually Incorporate Powdered Sugar
With the mixer running on low speed, gradually add the 3 cups powdered sugar over 3-4 minutes. This slow addition prevents clumping and ensures even distribution. After all the sugar is incorporated, increase the speed to medium and beat for an additional 2 minutes until the mixture is completely smooth and homogeneous. You'll notice the frosting become lighter in color as the butter fully emulsifies with the sugar.
At this stage, the frosting should resemble thick, pale yellow pudding. If you notice any dry spots or sugar granules, press them into the mixture with a spatula and continue mixing. The powdered sugar must be fully dissolved to achieve that signature Martha Stewart velvety texture. I like to run my finger through the frosting at this point—it should glide smoothly without any graininess.
Add Wet Ingredients for Stability
In a separate small bowl, whisk together the 0.5 cup heavy cream, 2 tbsp light corn syrup, 1 tsp lemon juice, 1 tsp pure vanilla extract, 0.25 tsp diamond crystal kosher salt, and 0.25 tsp almond extract (if using). The cold heavy cream is essential—it adds moisture without causing the frosting to become too soft. With the mixer running on low speed, slowly pour this mixture into the butter-sugar base while scraping down the sides of the bowl as needed.
Continue mixing on low speed for 2-3 minutes after all the wet ingredients are incorporated. This gradual addition prevents the frosting from curdling or becoming too runny. The lemon juice and corn syrup work together to create a stable emulsion that holds its shape when piped, while the salt and extracts enhance flavor without altering the texture. The frosting should now have a smooth, spreadable consistency similar to thick whipped cream.
Achieve Perfect Piping Consistency
Transfer the frosting to a piping bag fitted with a star tip (I prefer a Wilton 1M tip for decorative borders). Pipe a small test swatch onto parchment paper and let it sit at room temperature for 10 minutes. If the frosting spreads too much or loses its shape, refrigerate it for 15-20 minutes before piping. The ideal consistency should hold its shape when piped but still be soft enough to spread slightly with a spatula.
For best results, use the frosting within 3 hours of making it. If you need to store it, cover it tightly with plastic wrap pressed directly against the surface to prevent a skin from forming. When ready to use, let it sit at room temperature for 10-15 minutes before piping to bring it to the perfect working temperature. The frosting should be cool enough to hold its shape but still soft enough to pipe smoothly through the tip.
Pro Tips For Making Martha Stewart Sugar Cookie Frosting
- SOFTEN BUTTER FIRST: I used to just pull the butter straight from the fridge and beat it—big mistake. This frosting needs butter that’s just pliable, not melted or rock-hard. Let it sit at room temp for 30-45 minutes, then press it with your finger: if it leaves a slight dent, it’s ready. (Yes, even if you’re impatient like me.)
- WEIGH THE POWDERED SUGAR: Martha’s recipe calls for cups of powdered sugar, but scooping it straight from the box packs it unevenly. Use a kitchen scale for the 3 cups—it should weigh about 12 oz. Packed powdered sugar makes the frosting dense; fluffed sugar makes it airy. (Your future self will notice the difference.)
- SALT THE CORN SYRUP: The pinch of kosher salt in the corn syrup isn’t just for flavor—it balances the sweetness and keeps the frosting from tasting cloying. Skip it, and the frosting will taste like dessert and candy. (I learned this the hard way after making a batch that tasted like a sugar crash waiting to happen.)
- BEAT IN STAGES: Don’t dump all the powdered sugar at once and go full speed—you’ll end up with a gritty mess. Add 1 cup at a time, beating until smooth between additions. The corn syrup and vanilla go in last, and you’ll want to mix just until combined. Overmixing makes it grainy. (Sounds weird, but it works.)
Make-ahead tips for martha stewart sugar cookie frosting
Frosting Prep Ahead
Make this frosting up to 3 days in advance—its flavor actually deepens over time, becoming richer and more complex. Store it in an airtight container lined with parchment paper to prevent sticking. I like using glass jars with tight-sealing lids for easy portioning.
The frosting will firm up slightly in the fridge, so let it sit at room temperature for 10-15 minutes before whipping to restore smoothness. This head start means you can focus on decorating when the moment arrives. ✨
Cookie Prep Timeline
Bake your sugar cookies 1-2 days ahead and store them in airtight containers between layers of parchment paper. This prevents them from drying out or absorbing moisture from the frosting. I recommend baking them at 350°F for 8-10 minutes until the edges are just golden.
Let them cool completely before frosting—warm cookies will melt the butter in the frosting, creating a soupy mess. The cookies will taste even fresher when paired with the pre-made frosting. 💫
Frosting Portioning
Divide the frosting into small jars or silicone molds for easy reuse. I use 2-ounce ramekins for individual projects like cupcakes or 4-ounce jars for larger batches. Label each container with the date and intended use—this helps track freshness and prevents waste.
Portioned frosting thaws and re-whips beautifully, making it perfect for last-minute decorating. Store in the fridge for up to 5 days or freeze for 3 months for long-term prep. 🧊
Decorating Shortcuts
Pre-pipe decorative elements like roses or borders onto parchment-lined trays and store them in the fridge. These can be transferred directly to cookies when ready to serve. For filled cookies, pipe frosting into a piping bag with a large round tip, then sandwich two cookies together.
Chill for 15 minutes to set before serving. This method saves time and ensures professional-looking results every time. 🎨
Freezing for Later
Freeze frosting in 1-tablespoon portions for quick touch-ups or small projects. Wrap each portion tightly in plastic wrap and place in a freezer bag to prevent freezer burn. Thaw in the fridge overnight, then whip briefly to restore texture.
I’ve found that frozen frosting works best for filling cookies or quick glaze applications—it loses some of its pipeable stability but retains great flavor. Label with the date to track freshness. ❄️
Gift-Worthy Packaging
Package frosted cookies in clear cellophane bags tied with ribbon for a Martha Stewart-approved presentation. Store the cookies in the fridge for up to 3 days before gifting. The frosting stays fresh and vibrant, making these cookies perfect for holidays or special occasions.
I like adding a handwritten note with the recipe for a personal touch. This approach turns homemade treats into showstopping gifts. 🎁

Frequently asked questions
Why does Martha's frosting stay so stable when other recipes don't?
The secret lies in the corn syrup and cold butter combination. The corn syrup acts as a humectant, binding moisture to prevent weeping, while the cold butter creates a firm fat base that holds structure. The heavy cream adds moisture without destabilizing the mixture, and the lemon juice helps emulsify everything for that signature velvet texture.
Can I make this frosting without a stand mixer?
Yes, but you'll need to work carefully. Use a hand mixer and beat the cold butter for 3-4 minutes until fluffy, then gradually add the powdered sugar in ½-cup increments while mixing on low. For the wet ingredients, whisk them thoroughly in a separate bowl before adding. The key is patience—this method takes 10-15 minutes of active mixing, but you'll still achieve that smooth, pipeable consistency.
What's the best way to fix frosting that's too soft?
If your frosting is too runny, place the bowl in the freezer for 10-15 minutes while stirring occasionally. The cold will firm up the butter, restoring stability. For a quick fix, add 1 tablespoon more powdered sugar and mix until smooth. If it's still too soft, chill for another 5 minutes. Never add more butter—this will make it greasy and unstable.
How do I prevent my piped decorations from melting?
Always chill your frosting for 30 minutes before piping to firm up the butter. Work in a cool room (around 65°F) and avoid touching warm surfaces. For outdoor events, keep your piping bag in the fridge between uses. If decorations start to sag, place the tray in the freezer for 5 minutes to set them temporarily. The corn syrup in this recipe helps maintain structure even in warm conditions.
Can I color this frosting without changing the texture?
Use gel food coloring (like Wilton or Americolor) as it won't alter the moisture content like liquid dyes. Start with ½ teaspoon and mix gently—overmixing can incorporate air. For pastel shades, use ¼ teaspoon and add gradually. Avoid oil-based dyes as they can make the frosting too greasy. The color will be more vibrant if you tint the frosting just before piping.
