Ingredients for eileen's cookies frosting
Eight simple ingredients transform into the dreamy, pipe-perfect frosting Eileen swears by—every holiday season.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | 1 cup | Cold, cut into small cubes |
| Powdered Sugar 🍚 | 4 cups | Sifted for smooth texture |
| Vanilla Bean Paste 🌿 | 2 tbsp | High-quality, not extract |
| Heavy Whipping Cream 🥛 | ½ cup | Cold, full-fat preferred |
| Pure Vanilla Extract 🍯 | 1 tsp | Bottled, not imitation |
| Diamond Crystal Kosher Salt 🧂 | ¼ tsp | Fine grain for balance |
| Cornstarch 🌾 | 1 tbsp | For stability and smoothness |
| Lemon Juice 🍋 | 1 tsp | Freshly squeezed |
The butter is non-negotiable—unsalted, cold cubes whip into clouds, not butter. Grab European-style butter from Whole Foods or Trader Joe's if you want extra richness, but regular works fine. Vanilla bean paste? Penzeys or Williams Sonoma sell the good stuff—it’s worth the splurge for that deep, complex flavor. Powdered sugar should be sifted (trust me, it makes a difference), and if you’re using store-brand, sift it twice. The cornstarch is the secret weapon—it keeps your frosting from breaking down when you pipe those perfect swirls.
No vanilla bean paste? Double the extract, but you’ll miss the speckled seeds. Heavy cream too expensive? Half-and-half in a pinch, though it won’t whip as high. Swapping powdered sugar for granulated? Add 2 tbsp extra butter—it’s all about moisture balance. And if you’re allergic to cornstarch, arrowroot powder at the same amount works just as well. The lemon juice is optional but brightens the flavor—skip it if you’re not a fan of citrus notes. Pro tip: measure your powdered sugar by weight (4 cups = 1 lb) for foolproof consistency.
This frosting keeps beautifully—5 days in the fridge sealed in an airtight container, or 3 months frozen in a ziplock bag. Let it soften at room temp for 10-15 minutes before piping (microwave 10-second bursts if you’re in a hurry). For swirls that stay sharp, chill your piping bag in the freezer for 5 minutes before decorating. And if it gets too stiff? Warm it gently—never microwave directly, or you’ll end up with buttercream soup.

Step-by-step instructions for Eileen's cookies frosting recipe
Here's how to make frosting that stays pipeable all night with that signature vanilla bean swirl.
👨🍳 Step 1: Whip the Butter Until Light and Fluffy
First, pop your 1 cup of cold, cubed unsalted butter into the bowl of a stand mixer fitted with the paddle attachment. I like to cut the butter into small cubes so it incorporates faster and more evenly. Whip on medium speed for 3-4 minutes until the butter is completely smooth and pale in color—this means it's fully aerated.
Watch for the butter to nearly double in volume and become almost fluffy. You'll know it's ready when you can draw a line in the butter with your finger that stays for a few seconds. This step is crucial—it creates the light, airy base that makes the frosting pipeable and prevents that dreaded "grainy" texture.
👨🍳 Step 2: Gradually Add Powdered Sugar and Cream
With the mixer running on low speed, slowly add the 4 cups of sifted powdered sugar and the 0.5 cup of cold heavy whipping cream simultaneously. I use a fine-mesh sieve for the powdered sugar to prevent any lumps from forming—this keeps the frosting silky smooth. Add them gradually so the mixture can incorporate properly without making a mess.
Once all the sugar and cream are added, increase the speed to medium and beat for another 3-4 minutes until the mixture is completely smooth and creamy. You should be able to pipe it through a star tip without any resistance. If it's too thick, add 1 teaspoon of lemon juice at a time until you reach the perfect consistency—it should hold its shape when piped but still be smooth enough to swirl.
🍳 Step 3: Incorporate Vanilla and Stabilizers
Add the 2 tablespoons of vanilla bean paste, 1 teaspoon of pure vanilla extract, 0.25 teaspoon of diamond crystal kosher salt, and 1 tablespoon of cornstarch to the mixer. Mix on low speed for 1 minute just until fully combined. The cornstarch acts as a stabilizer, keeping the frosting firm at room temperature while still being pipeable.
Here's the thing—the vanilla bean paste is what gives this frosting its signature depth and those beautiful swirls. Don't skimp on quality here. The salt balances the sweetness, and the lemon juice adds a subtle brightness that keeps the flavor from getting too heavy. Taste a small spoonful to check the balance—it should be sweet but not cloying, with a rich vanilla flavor that lingers.
⏰ Step 4: Chill and Test for Piping Perfection
Transfer the frosting to a piping bag fitted with a star tip (I like a Wilton 1M tip for that classic swirl). Chill in the refrigerator for at least 1 hour—this is non-negotiable. The cold temperature firms up the frosting, making it hold its shape beautifully when piped onto cookies. If you're in a hurry, pop it in the freezer for 20-30 minutes, but don't over-chill or it'll get too stiff.
After chilling, give the frosting a quick stir to redistribute any separated ingredients. Test the consistency by piping a small swirl onto a plate. It should hold its shape without spreading too much, but still be smooth enough to create those elegant swirls. If it's too thick, add 1 teaspoon of lemon juice at a time until it reaches the perfect consistency. The frosting should be cool to the touch but still pliable—this is the sweet spot for piping.
🍽️ Step 5: Pipe and Swirl Like a Pro
Pipe generous swirls onto your cooled cookies, starting from the center and working your way outward. I like to make two overlapping swirls per cookie for that classic look. Use a small offset spatula to create the signature "rosette" shape by gently pulling the frosting outward from the center. Work quickly but carefully—this frosting stays pipeable for hours, but it's best used within 4-6 hours of making it.
Here's a pro tip: if you're making these ahead of time, store the frosting in an airtight container in the fridge. Bring it to room temperature before piping, and give it a quick whip with the paddle attachment to restore its smooth texture. The frosting will keep in the fridge for up to 5 days, making it perfect for prepping ahead for parties or cookie exchanges. Enjoy your showstopping cookies!
Pro Tips For Making Eileen'S Cookies Frosting
- SOFTEN BUTTER PROPERLY: Take your butter out of the fridge exactly 1 hour before whipping—no more, no less. I used to eyeball it and end up with either grainy lumps (if too cold) or melted butter (if too warm), both of which ruin the texture. Room temp is the only temp that gives you that silky, pipeable consistency.
- SCALE THE SUGAR: Weigh your powdered sugar instead of scooping. A standard cup of powdered sugar can vary by 2-3 ounces, and that’s the difference between frosting that’s spreadable and frosting that’s a dry, crumbly mess. If you’re in a pinch, spoon it into the cup and level it off—don’t pack it down.
- WHIP IN STAGES: Don’t dump all the heavy cream at once. Start with half, whip until soft peaks form, then add the rest. This keeps the frosting light and airy instead of turning it into a dense, buttercream brick. I learned this after making a batch that looked like it could’ve been used as a doorstop.
- CHILL THE VANILLA: Pop your vanilla bean paste in the fridge for 10 minutes before adding it to cold butter. The cold paste blends more smoothly and doesn’t turn your frosting into a warm, soupy disaster. Yes, it’s a tiny step, but it makes a real difference in flavor distribution—no clumpy bits or overpowering bursts of vanilla.

Frequently asked questions
Why does this frosting stay pipeable longer than other buttercreams?
The cornstarch and chilled butter create a stable structure that prevents melting. The 1-hour refrigeration firms it up while keeping it smooth, unlike regular buttercream that softens quickly. This is why it holds those perfect swirls for hours without collapsing!
Can I make this frosting without a stand mixer?
Use a hand mixer or even a whisk in a large bowl. Work in small batches and whip the butter by hand until pale and fluffy—it'll take longer but still work. The key is patience: keep mixing until fully aerated before adding sugar. For best results, chill between additions to prevent overheating.
What if my frosting turns grainy?
Graininess happens when butter isn't fully whipped or sugar isn't sifted. Fix it by adding 1-2 teaspoons of heavy cream and whipping again. For prevention, always use cold butter, sift powdered sugar, and whip on medium speed until completely smooth. The cornstarch helps prevent this, but extra cream brings it back to perfection.
How do I get those perfect rosette swirls?
Use a Wilton 1M tip and pipe two overlapping swirls per cookie. After piping, gently pull the frosting outward with an offset spatula to create the rosette shape. Work quickly while the frosting is still cool—warmth makes it too soft to hold. Chill your piping bag for 5 minutes before decorating for extra stability.
Can I color this frosting for special occasions?
Yes! Use gel food coloring (liquid colors can make it too runny). Add just a few drops at a time while mixing on low speed. For pastel shades, start with ½ teaspoon and adjust. The cornstarch helps the color distribute evenly without altering the texture. Pro tip: tint a small batch first to test the shade before coloring the whole batch.
