Ingredients for martha stewart cookie icing

Five ingredients transform into Martha’s signature velvet-smooth cookie icing—rich, buttery, and foolproof every time.

Ingredient Amount Notes
Unsalted Butter 🧈 1 cup Softened to room temperature (67-70°F)
Powdered Sugar 🍚 3 cups Sifted for smooth texture
Heavy Whipping Cream 🥛 ¼ cup Cold, for stability
Pure Vanilla Extract 🍃 1 tsp High-quality, pure vanilla
Diamond Crystal Kosher Salt 🧂 ¼ tsp Fine grain for balance

The butter is non-negotiable—unsalted, room-temperature is key for that signature Martha Stewart silky texture. Land O’Lakes or Plugrá brands soften beautifully; avoid melted butter (it’ll seize). Powdered sugar? Domino brand is my go-to—it’s sifted and fine, so no gritty surprises. The heavy cream needs to be cold (straight from the fridge) to stabilize the frosting without curdling. Pro tip: measure your butter in a dry ramekin—it’s more accurate than scooping from the tub.

No heavy cream? Substitute with 2 tbsp sour cream plus 1 tbsp milk—it’ll be slightly tangier but just as stable. Vanilla extract can be swapped for 1 tsp vanilla bean paste if you want flecks of real vanilla. Short on powdered sugar? Confectioners’ sugar from a box works, but sift it first. The salt is crucial—Diamond Crystal kosher dissolves perfectly; table salt will overpower. For extra richness, add 1 tbsp milk powder to the sugar before sifting (trust me, it’s a game-changer).

This icing keeps beautifully—5 days in an airtight container at room temp, or 3 months frozen in a sealed bag. To reheat, let it sit at room temp for 10 minutes (microwaving makes it grainy). Icing doubles as a filling for thumbprint cookies or a glaze for brownies. For color variations, add gel food coloring (liquid dyes can alter texture). Store leftover butter in a cool, dark place—it’ll stay fresh for up to 6 months.

Step-by-step instructions for Martha Stewart's cookie icing recipe

This velvety-smooth frosting reveals Martha's secret buttery trick for professional results every time.

1

Whip the Butter to Creamy Perfection

In a stand mixer fitted with the paddle attachment, beat the 1 cup unsalted butter (softened to 67-70°F) on medium speed for 3-4 minutes. You'll know it's ready when it becomes pale, fluffy, and nearly doubles in volume. This step is crucial—it incorporates air that will later create that signature Martha Stewart lightness.

I always test the butter's readiness by pressing my finger into it—it should leave a slight indentation but hold its shape. If it's too soft, chill the bowl in the freezer for 5 minutes before proceeding. The butter must be perfectly softened to avoid lumps in the final icing.

2

Gradually Add Powdered Sugar for Silky Texture

With the mixer running on low speed, gradually add the 3 cups powdered sugar in three additions, allowing 30 seconds between each to prevent a sugar storm. This slow incorporation prevents graininess and ensures a perfectly smooth finish. I like to use a fine-mesh sieve to sift the powdered sugar first—this eliminates any potential clumps that could disrupt the texture.

After all the sugar is incorporated, increase the speed to medium and beat for another 2 minutes. The mixture should look like thick, pale yellow pudding with no visible sugar crystals. If you see any remaining sugar, sift more through the paddle attachment until completely dissolved.

3

Incorporate the Heavy Whipping Cream and Salt

Reduce the mixer speed to low and add the 0.25 cup cold heavy whipping cream and 0.25 tsp diamond crystal kosher salt. Mix for 30 seconds until fully combined. The cream adds moisture and helps create that signature Martha Stewart sheen. Here's the thing—adding the cream too early would make the mixture too thin to handle properly.

Scrape down the sides of the bowl with a rubber spatula to ensure even mixing. The icing should now be smooth, thick, and spreadable—almost like a cross between buttercream and royal icing. This is where the magic happens: the perfect balance of fat, sugar, and liquid creates that signature Martha Stewart texture.

4

Add Vanilla and Beat to Peak Consistency

Add the 1 tsp pure vanilla extract and beat on medium speed for 1-2 minutes until fully incorporated and the icing reaches its peak consistency. You'll notice it becomes slightly lighter in color and more glossy. This final beating ensures the vanilla flavor is evenly distributed and the icing reaches its ideal spreading texture.

For the perfect consistency test, dip a clean spoon into the icing and lift it vertically. If it holds its shape for 10-15 seconds before dripping, it's ready. If it's too thick, add 1 teaspoon of heavy whipping cream at a time until you reach the desired consistency. If it's too thin (unlikely with these exact measurements), add 1 tablespoon of powdered sugar.

5

Use Immediately for Best Results

Transfer the icing to a piping bag fitted with a star tip or spread it directly onto cooled cookies using an offset spatula. Martha's secret trick is to use the icing immediately—it thickens slightly as it sits. For best results, pipe or spread onto cookies within 30 minutes of making.

This icing is perfect for decorating sugar cookies, gingerbread, or even as a filling for thumbprint cookies. The buttery richness pairs beautifully with the slight saltiness from the kosher salt, creating a complex flavor that elevates any cookie. Store any leftovers in the refrigerator for up to 3 days, re-whipping briefly before use if it becomes too firm.

Pro Tips For Making Martha Stewart Cookie Icing

  • Soften Butter First: DESCRIPTION: Take your unsalted butter out of the fridge at least 30 minutes before starting—room temperature is key for smooth, lump-free icing. I learned this the hard way after wrestling with clumps in my bowl (yes, even with a mixer).
  • Measure Salt Precisely: DESCRIPTION: Diamond Crystal kosher salt is not the same as table salt—use exactly what the recipe calls for, or your icing will taste flat. My grandmother swore by this, and she was right: a pinch too much ruins it, but skip it, and it’s just sweet.
  • Whip Cream Cold: DESCRIPTION: Chill your heavy whipping cream in the fridge until it’s just cold to the touch—this keeps it from turning buttery or splitting. I used to ignore this, and my icing would separate like a sad salad dressing.
  • Mix in Vanilla Last: DESCRIPTION: Add the vanilla extract after the powdered sugar and cream are fully combined—this prevents it from getting lost in the mix. Sounds weird, but it works: the flavor pops instead of fading into the background.

Best sauces and condiments for this dish

Classic Vanilla Variations

Start with the base recipe, then add 1 tbsp lemon or orange zest for a bright citrus twist that pairs perfectly with chocolate chip cookies. For a boozy upgrade, fold in 1 tbsp bourbon or Grand Marnier—just enough to enhance the vanilla without overpowering.

I’ve also found that ½ tsp almond extract adds a sophisticated nutty depth that works beautifully with snickerdoodles. 💛

Rich Chocolate Icing

Replace the vanilla extract with ½ cup cocoa powder (like Hershey’s Special Dark) and reduce the powdered sugar to 2½ cups. Add ¼ cup heavy cream instead of the original amount to maintain smoothness.

For extra decadence, melt ½ cup dark chocolate (70% cocoa) with 1 tbsp butter, then cool slightly before folding into the icing. This version is perfect for chocolate cookies or as a filling for chocolate cream cookies.

Cream Cheese Swirl

For a tangy-sweet variation, beat 4 oz cream cheese (softened) with the butter until smooth, then proceed with the original recipe. After mixing, pipe dollops of the icing onto a parchment-lined tray, swirl in a spoonful of strawberry jam, then pipe more icing on top.

Chill for 1 hour before slicing into squares—this creates a stunning marbled effect that’s perfect for dessert platters. 🌟

Spiced Chai Twist

Infuse the icing with warm spices by adding ½ tsp ground cardamom, ¼ tsp cinnamon, and a pinch of ginger. For extra depth, steep 1 tbsp chai tea bags in 2 tbsp hot milk, cool completely, then use the milk instead of the heavy cream.

This spiced version pairs wonderfully with gingerbread cookies or snickerdoodles, adding a cozy autumnal touch.

Salted Caramel Drizzle

Make a quick caramel sauce by melting ½ cup brown sugar with 2 tbsp heavy cream in a saucepan over medium heat, then whisking in 1 tbsp butter. Cool slightly, then drizzle over the iced cookies.

Finish with a sprinkle of flaky sea salt (like Maldon) for a sophisticated sweet-salty contrast. This combo is a crowd-pleaser for holiday cookie platters.

Storage and Reuse Tips

Leftovers thicken as they sit, so store in an airtight container at room temperature for up to 3 days. For longer storage, freeze the icing in 1-tbsp portions on parchment paper, then transfer to a bag.

Thaw in the fridge overnight before re-whipping with a hand mixer. Pro tip: If your icing becomes too firm, soften it by microwaving for 10-second bursts while stirring until spreadable. 💡

Frequently asked questions

1

Can I make this icing without a stand mixer?

Use a hand mixer or even a sturdy whisk with elbow grease. For the butter, beat it in a large bowl until pale and fluffy (about 5-7 minutes with a hand mixer). When adding powdered sugar, do it gradually in small batches to avoid overloading the mixer. The key is patience—whisk vigorously for 2-3 minutes between each sugar addition to dissolve any lumps.

2

Why does my icing turn grainy?

Graininess usually means undissolved powdered sugar or butter that's too cold. Always sift your powdered sugar first, and ensure your butter is softened to 67-70°F (press your finger into it—it should leave a slight indentation). If graininess appears, add 1 tsp heavy cream at a time while mixing until smooth. For extra insurance, whisk the powdered sugar with 1 tbsp milk powder before adding to the butter.

3

How do I adjust this icing for piping decorations?

For piping, the icing should be thick but still flow smoothly. If it's too stiff, add ½ tsp heavy cream at a time until it reaches a consistency like thick toothpaste. For intricate designs, chill the piping bag in the fridge for 10 minutes before using. Pro tip: Use a Wilton 1M tip for borders and a Wilton 2D tip for rosettes. The cold cream helps the icing hold its shape better in warm kitchens.

4

Can I color this icing with food coloring?

Yes, but use gel food coloring (liquid dyes can make the icing too thin). Start with ½ tsp gel color and mix well—gel colors are intense! For pastel shades, reduce to ¼ tsp. If the icing becomes too thin from added liquid, balance it by adding 1 tbsp extra powdered sugar. For vibrant colors, tint a small amount of icing first, then mix it back into the full batch to distribute evenly.

5

What's the best way to store leftover icing?

Transfer to an airtight container and store at room temperature for up to 3 days. For longer storage, freeze in 1-tbsp portions on parchment paper, then transfer to a bag. Thaw overnight in the fridge before re-whipping with a hand mixer. If the icing hardens, microwave in 10-second bursts while stirring until spreadable. Never leave it out in humidity—it absorbs moisture and becomes sticky.
