Swapping butter for margarine, shortening, cream cheese, heavy cream, or egg whites keeps the powdered-sugar base intact while opening up new flavor options. Each substitute pairs with a specific dessert and consistency, because a tender angel-food cake and a stack of sturdy sugar cookies call for very different finishes. Measure carefully, sift the sugar, and adjust the liquid by the teaspoon until the texture is right.
This guide explains how to make icing without butter, walks through four simple recipes, and helps home bakers match each finish to the right dessert, from airy angel-food cake to sturdy sugar cookies.
Why Bakers Skip Butter in the First Place
Lactose intolerance affects roughly 65% of the global population, and dairy allergies touch about 2% of adults, according to U.S. National Institutes of Health data. Add a vegan community nearing 4% of the United States, based on a 2023 Gallup poll, and the demand for a butterless icing recipe that still spreads cleanly becomes obvious. Those numbers explain the quiet shift away from classic American Buttercream in home kitchens.
Dietary, Texture, and Flavor Reasons
Dietary needs drive most of the search, yet texture plays a real role too. Royal icing dries to a porcelain-hard shell that buttercream cannot match for gingerbread houses or detailed cookie work. Whipped cream frosting gives a cloud-soft finish that buttercream can only approximate.
Sometimes the butter simply runs out at 9 p.m., the kids are waiting, and the grocery store is closed, so a pantry of powdered sugar, milk, and cream cheese pulls you out of trouble. A tablespoon of butter carries about 7 grams of saturated fat, which is why whipped cream or a simple glaze offers a noticeably lighter celebratory finish.
The Four No-Butter Icings Every Baker Should Know
Four recipes cover nearly every dessert on a home baker’s calendar. Each one brings its own flavor, dairy footprint, and ideal canvas, so the choice depends on what you’re topping.
| Icing Type | Best For | Dairy Footprint | Key Texture |
|---|---|---|---|
| Cream Cheese Icing | Carrot cake, red velvet, cinnamon rolls | Dairy-light (contains cream cheese) | Thick, tangy, spreadable |
| Royal Icing | Sugar cookies, gingerbread, decorative work | Fully dairy-free | Hard-setting, glossy |
| Sugar Glaze | Donuts, bundt cakes, pound cakes, fruit tarts | Dairy-light with milk; dairy-free with water | Thin, pourable, glossy |
| Whipped Cream Icing | Genoise, angel food, shortcakes | Dairy-light (contains heavy cream) | Light, cloud-soft, holds soft peaks |
Cream cheese icing leans tangy and dense, so it pairs naturally with spiced or chocolate cakes where its acidity cuts the sweetness. Royal icing is the only fully dairy-free option in the group, making it the safe pick for vegan baking. A sugar glaze sets fast and dries to a thin, crackled sheen. Whipped cream frosting is the gentlest of the four, so save it for cakes that need a delicate finish.
With those four icings in hand, knowing which ingredient swaps actually mimic butter becomes the next practical step.
Ingredient Swaps That Replace Butter Cleanly
Most butter substitutes work as a straight 1:1 swap by volume, which keeps your existing favorite recipe intact. Bring the swap to room temperature before mixing, otherwise it clumps against the sugar and never smooths out.
Margarine, Shortening, and Cream Cheese
Margarine and vegetable shortening step in for butter at equal volumes and behave almost identically in mixing. Shortening produces a slightly whiter, stiffer buttercream that holds piping details beautifully, which is why Wilton decorator icing recipes lean on it. Cream cheese works solo, with no butter needed, and brings a tang that flatters carrot, banana, and red velvet cakes. None of these swaps are dairy-free, so check labels for vegan brands like Earth Balance if that matters.
Liquid and Stabilizer Swaps
Heavy cream whipped with powdered sugar makes a feather-light alternative to butter-based buttercream. Oat, almond, or soy milk stand in for dairy milk in glazes, which keeps the recipe vegan-friendly. A teaspoon of cornstarch whisked into powdered sugar prevents clumping and helps thin glazes hold their shape on a cake. Meringue powder, sold under brands like Wilton, stabilizes royal icing against humidity, which matters when you’re decorating in a warm kitchen.
Always sift your powdered sugar before mixing, even when the bag looks fine. A quick pass through a fine mesh sieve breaks up clumps and prevents grainy pockets in the finished icing.
Step-by-Step Recipes You Can Mix in Minutes
Each recipe below uses common pantry staples and finishes in under ten minutes of active work. Measure by the cup, beat until smooth, and adjust by the teaspoon at the end to reach the exact consistency your dessert demands.
Cream Cheese Icing
Creaming 8 ounces of room-temperature cream cheese with 4 cups of sifted powdered sugar, 1 teaspoon of vanilla extract, and a pinch of salt on medium speed yields a silky icing in about 3 minutes. Scrape the bowl halfway through. The finished icing should ribbon off the beater and hold a soft peak when you lift it.
Royal Icing
Whip 2 large egg whites to soft peaks with a stand mixer. With the mixer running, stream in 3 cups of sifted powdered sugar, 1 teaspoon of lemon juice, and a pinch of salt. Continue beating on high until stiff, glossy peaks form, around 4 to 5 minutes. Add water by the quarter-teaspoon for piping consistency, or leave it thicker for flood-work.
Sugar Glaze
Stir 2 cups of sifted powdered sugar with 2 to 3 teaspoons of milk (or water for dairy-free) in a small bowl. Add liquid one teaspoon at a time until the glaze ribbons off a spoon. Stir in 1/2 teaspoon of vanilla extract or a squeeze of lemon for brightness. A teaspoon of cornstarch stiffens it for a thicker coat on donuts and bundt cakes.
Whipped Cream Icing
Chill the bowl and whisk in the freezer for 10 minutes. Pour in 1 cup of cold heavy cream, add 2 tablespoons of powdered sugar and 1/2 teaspoon of vanilla extract, then beat on medium-high until soft peaks form. Stop the moment the cream holds a curl, because over-beating turns it into butter, which defeats the purpose.
Adjust each batch by the teaspoon to land on the right consistency. Spreadable icing should droop off a spatula in a slow wave. Pipeable icing should hold a sharp edge when you lift the tip. Drizzle-ready glaze should pour in a steady ribbon and disappear into the surface within a few seconds.
Once the recipes feel second nature, pairing each icing with the cake it’s meant for prevents the texture from working against the dessert.
Matching Each Icing to the Right Dessert
Texture and flavor alignment matter as much as the recipe itself. A delicate cake crushed under heavy frosting is a sad sight, and a flat glaze on a cookie that needs structure fails just as quickly.
Cakes and Cupcakes
Cream cheese icing belongs on carrot cake, red velvet cupcakes, banana bread, and warm cinnamon rolls, where its tang balances the sweetness. Whipped cream icing shines on genoise, angel food, strawberry shortcakes, and any cake where you want the crumb to lead. Sugar glaze is the right finish for bundt cakes, pound cakes, and fruit tarts, where a thin, glossy coat is the goal. Royal icing works only on sturdy surfaces like cookies or gingerbread.
Cookies and Decorative Work
Royal icing is the only option here, because nothing else dries hard enough to stack. Mix it thicker for outlining, thinner for flooding. Sugar glaze works in a pinch for a softer, crackled finish on shortbread.
Dairy-Free and Vegan Callouts
Only royal icing is fully dairy-free as written. For the others, swap dairy milk for oat or soy milk in glazes, use vegan cream cheese in cream cheese icing, and reach for coconut cream in whipped cream frosting. Each substitution shifts flavor slightly, so taste as you go.
Troubleshooting Texture, Flavor, and Storage
Even experienced bakers hit snags with butter-free icing, usually because humidity, temperature, or measuring crept in. Most problems fix themselves with one extra ingredient and a minute of mixing.
| Problem | Likely Cause | Quick Fix |
|---|---|---|
| Too runny | Too much liquid, warm ingredients | Add powdered sugar by the tablespoon or chill 15 minutes |
| Grainy or gritty | Unsifted sugar, under-mixing | Sift sugar first; beat 1 to 2 minutes longer |
| Too sweet or flat | No acid or salt | Add a pinch of salt, a squeeze of lemon, or extract |
| Royal icing cracks or weeps | Humidity, old egg whites | Add 1 teaspoon meringue powder; work in a cool, dry room |
| Whipped cream deflates | Warm bowl, over-beating | Chill bowl again; stop at soft peaks |
Royal icing made with raw egg whites carries a small salmonella risk. For vulnerable eaters, use pasteurized eggs or swap in a meringue powder recipe that calls for water.
Storage Timelines by Icing Type
Cream cheese icing keeps up to one week refrigerated in an airtight container; bring it to room temperature and re-whip briefly before using. Royal icing stores up to two weeks sealed at room temperature, though colored icing may bleed. Sugar glaze lasts one to two days refrigerated and may need a splash of milk to loosen. Whipped cream icing is best within 24 hours, after which it weeps and deflates.
To revive any stiffened batch, let it sit at room temperature for 15 minutes, then beat on low just until smooth.
Storage hiccups are often the last hurdle, so a few quick fixes will keep every batch usable.
Key Takeaways
Butter is one ingredient among many, not the backbone of every great icing. Pick the substitute that fits the dessert: cream cheese for spice cakes, royal icing for cookies, glaze for donuts and bundts, whipped cream for tender layers. Sift your sugar, mind your temperatures, and trust the teaspoon-level adjustments at the end.
FAQ
Can you make icing without butter?
Yes. Powdered sugar forms the base of nearly every butter-free icing, and you can build a smooth, spreadable topping from cream cheese, heavy cream, egg whites, or just milk and sugar alone. The trick is matching the swap to the dessert and adjusting the liquid by the teaspoon until the consistency is right.
What can I use instead of butter in icing?
Margarine or vegetable shortening work as 1:1 swaps by volume. Cream cheese, heavy cream, and coconut cream each give a distinct flavor and texture, so the best pick depends on whether you want tang, lightness, or richness. For dairy-free baking, oat milk, almond milk, and vegan butter sticks all perform well in tested recipes from brands like Wilton.
How do you make frosting without butter or milk?
Whip egg whites with powdered sugar and a squeeze of lemon for royal icing, or stir powdered sugar with water and a teaspoon of cornstarch for a simple glaze. Both recipes are fully dairy-free and shelf-stable enough for most cookie and cake projects.
Is butter necessary for icing?
No. Butter gives American Buttercream its signature richness and structure, but Swiss Meringue Buttercream, royal icing, cream cheese frosting, and whipped cream frosting all prove that a great icing can exist without it. Each alternative has its own ideal use case, from delicate layer cakes to decorated cut-out cookies.
How do you make powdered sugar icing without butter?
Stir sifted powdered sugar with milk (or water), a splash of vanilla extract, and a pinch of salt until the glaze ribbons off a spoon. For a thicker consistency, add a teaspoon of cornstarch or swap in cream cheese for the liquid and beat until smooth.
What is the best butter substitute for frosting?
Vegetable shortening holds piping details best and produces a pure-white finish that takes food coloring cleanly. Cream cheese brings the best flavor for spice and chocolate cakes. Heavy cream gives the lightest result on delicate cakes, while margarine is the closest 1:1 swap when you want a nearly identical buttercream experience.
