Whisk pasteurized egg whites with powdered sugar until thick and glossy to make simple two-ingredient icing for cookies and cakes.
If you have ever typed “how to make icing using egg white and sugar only?” into a search bar right before guests arrive, you are not alone. Two pantry items, one bowl, and a whisk are all you need for a glossy icing that dries firm on cookies, holds shapes on cakes, and tastes clean and sweet. The method is short, but a few small details decide whether you get silky ribbons or a runny puddle.
This style of icing is a close cousin of classic royal icing. Egg whites give structure, while fine sugar forms a smooth, stable coating that sets on the surface. You can make it with a hand whisk or mixer, adjust it for piping or flooding, and scale the batch for a single batch of cookies or a big decorating session.
Raw egg white icing brings food safety questions, though. The good news is that using pasteurized egg whites and following basic handling advice from agencies such as the FDA keeps risk lower while still giving you that crisp, glossy finish you want on your bakes.
Why This Two-Ingredient Icing Works
Egg whites are mostly water and proteins. When you beat them, those proteins unfold and trap tiny air bubbles, turning clear liquid into a white foam. When you add powdered sugar, the sugar crystals pull water away from the foam and tighten that network, so the mixture thickens and becomes shiny and smooth.
Powdered sugar (also called confectioners’ sugar or icing sugar) works far better than granulated sugar here. The fine grind dissolves fast and gives a silky finish, while the small amount of starch in most brands helps the icing dry and stay stable on cookies for hours at room temperature.
Basic Ratios For Egg White Sugar Icing
You can adjust the amount of powdered sugar you add to each egg white to change how thick the icing feels. The table below gives starting ratios for a range of uses. Each row assumes a large pasteurized egg white, about 30 grams.
| Use | Egg White | Powdered Sugar |
|---|---|---|
| Stiff Piping (flowers, borders) | 1 large egg white | 2 3/4–3 cups (330–360 g) |
| Medium Piping (outlines, writing) | 1 large egg white | 2 1/4–2 1/2 cups (270–300 g) |
| Flooding Cookies (fill-in icing) | 1 large egg white | 2–2 1/4 cups (240–270 g) |
| Soft Drizzle For Cakes | 1 large egg white | 1 3/4–2 cups (210–240 g) |
| Thin Glaze For Quick Dipping | 1 large egg white | 1 1/2–1 3/4 cups (180–210 g) |
| Gingerbread House “Glue” | 1 large egg white | 3 cups (360 g), very stiff |
| Small Test Batch | 1/2 egg white (about 15 g) | 1–1 1/4 cups (120–150 g) |
Treat these ratios as a starting point. Humidity, egg size, and sugar brand all shift the texture slightly. You can always whisk in a spoon or two of extra sugar to stiffen the icing or a teaspoon of water to loosen it.
How To Make Icing Using Egg White And Sugar Only? (Step-By-Step)
The core method for how to make icing using egg white and sugar only is simple, but the order and speed of mixing matter. Go slowly with the sugar and stop whisking as soon as the icing looks thick and satiny.
Ingredients
- 2 large pasteurized egg whites (about 60 g total)
- 4–5 cups (480–600 g) powdered sugar, sifted
This makes enough icing to outline and flood about 2–3 standard trays of cookies, depending on design and thickness.
Equipment
- Medium mixing bowl (glass or metal)
- Hand mixer or stand mixer with whisk attachment (a sturdy whisk works too)
- Fine sieve for sifting sugar
- Rubber spatula
- Piping bags or small food-safe bags (optional, for decorating)
Step-By-Step Method
- Separate the egg whites.
Crack each egg over a small bowl and pass the yolk back and forth between the shell halves, letting the white fall into the bowl. Move the clean whites into your mixing bowl. If even a little yolk slips in, scoop it out with a clean spoon. - Whisk to a light foam.
Beat the egg whites on low to medium speed until they look foamy and slightly opaque. You are not aiming for full meringue here; a loose foam helps the sugar blend smoothly. - Sift in the first portion of sugar.
Add about one cup of powdered sugar through the sieve while the mixer runs on low. Let it mix until the sugar disappears and the mixture looks smooth. - Keep adding sugar gradually.
Continue adding sugar in half-cup portions, letting each addition fully blend before the next. Scrape down the bowl once or twice so no dry sugar hides on the sides. - Adjust to your target texture.
When the icing starts to hold soft peaks, slow down and check often. For piping outlines, you want a thick icing that forms peaks which gently fold over. For flooding cookies, you want a ribbon that disappears back into itself within about 10–15 seconds. - Rest the icing briefly.
Let the bowl sit for 5–10 minutes. Tiny air bubbles rise to the top during this rest, which makes for smoother lines when you pipe. - Transfer to bags or cover the bowl.
Spoon the icing into piping bags, or press plastic wrap directly onto the surface in the bowl. Direct contact helps prevent a dry skin from forming.
Checking The Texture By Sight And By Spoon
For most cookie decorating, home bakers like to work with two textures at once: a thicker icing for outlines and a slightly looser version for flooding. Take a spoonful of your batch and drop it back onto the surface. Count how long it takes for the line to settle.
If the ribbon disappears in under five seconds, the icing is thin and works best for flooding large areas. If the line stays on top past fifteen seconds, it is on the stiff side and suits piping fine lines or small details. Adjust by adding little bumps of sugar or drops of water until the behavior matches the job you have in mind.
Tips For Making Icing With Egg White And Sugar Only At Home
Small habits during mixing make this two-ingredient icing easier to work with and more reliable from batch to batch. These tips help whether you are decorating holiday cookies or putting fast lines on a weekday cake.
- Use pasteurized egg whites whenever you can.
Cartons of liquid egg whites that are labeled pasteurized are designed for recipes like this and sidestep part of the safety concern around raw shell eggs. - Sift the sugar once or twice.
Lumps of powdered sugar cause clogs in piping tips and give a bumpy surface. Sifting right before mixing keeps the texture smooth. - Keep fat away from the bowl.
Even a smear of oil or grease can flatten the foam and weaken the icing. Use clean, dry tools and avoid plastic bowls that tend to hold onto fat. - Color and flavor gently.
Gel food colors and concentrated extracts add less liquid than liquid drops. They change the texture less, so you keep the consistency you worked to reach. - Cover icing you are not using.
When you pause, cover bowls and bag tips. A thin crust forms fast on exposed icing, and those flakes can drag across your designs.
Egg Safety When Using Raw Egg Whites
Food safety authorities warn that raw or undercooked eggs can carry Salmonella bacteria, which cause foodborne illness. The U.S. Food and Drug Administration points out that even eggs with clean, uncracked shells may contain bacteria and recommends careful handling, chilling, and cooking for egg dishes and egg-based foods. FDA egg safety advice
The U.S. Department of Agriculture notes that raw shell eggs are not recommended for foods that stay uncooked. USDA egg product safety guidance Because icing with egg white and sugar only is not heated after mixing, it falls into that higher-risk group.
For healthy adults, many bakers still choose to use this icing, especially with pasteurized egg whites and a high ratio of sugar, which reduces available moisture. People who are pregnant, older, very young, or have weaker immune defenses should avoid raw egg recipes and stick to icings made with cooked components or meringue powder. If you plan to sell baked goods, check local rules for egg-based decorations as well.
Coloring And Flavoring Egg White Sugar Icing
The base recipe follows the promise in the question: egg whites and sugar only. Once you are comfortable with that core, you might want gentle flavor or color for holiday cookies or birthday cakes. A few drops of gel food color or a small amount of extract will not disturb the structure as long as you add them late and mix lightly.
Adding Color
Gel and paste colors are the easiest way to tint icing. Place a little icing in a small bowl, touch a toothpick into the gel, then stir that tiny amount into the bowl. It is easier to deepen a shade than to walk it back, so start with less than you think you need.
If you plan to flood cookies, keep each color at the same thickness so the surface dries evenly. When you add liquid color instead of gels, adjust with a spoonful of extra sugar if the icing looks thinner than before.
Adding Flavor
Vanilla, almond, or lemon extract can soften the straight sugar taste. Add a quarter to half a teaspoon per batch to start, then taste. Strong flavors like peppermint can dominate quickly, so touch them in with care.
Troubleshooting Egg White And Sugar Icing
Even when you follow the method, small changes in room temperature or measuring can cause problems. This section gathers common icing issues and simple fixes so you can rescue a batch instead of tipping it down the sink.
Common Problems And Quick Fixes
| Problem | Likely Cause | Quick Fix |
|---|---|---|
| Icing too runny | Too little sugar or extra liquid from color or extract | Whisk in powdered sugar, 1–2 tablespoons at a time |
| Icing too stiff | Too much sugar or long mixing time | Stir in water, 1/2 teaspoon at a time, by hand |
| Grainy texture | Undissolved sugar or old, clumpy sugar | Let icing rest 10 minutes, then whisk again; next time sift sugar |
| Air bubbles on the surface | High mixing speed and fast piping | Tap the bowl on the counter and gently stir before piping |
| Crusting in the bowl | Surface left uncovered | Press plastic wrap directly on the surface between uses |
| Icing will not dry hard | Too little sugar or very damp room | Add a little sugar and allow longer drying time in a dry space |
| Dull finish | Overmixing or high humidity | Stop mixing when icing looks glossy, then dry in a cool room |
When you change a batch, move slowly. Stir extra sugar or water in by hand rather than turning the mixer back on every time. Mechanical whipping adds more air, which can lead to bubbles and a chalky surface once the icing dries.
Storing And Using Leftover Icing
Icing made with egg white and sugar only is best on the day you mix it, but you can hold leftovers for short periods. Press plastic wrap onto the surface, seal the bowl, and place it in the refrigerator for up to two days if you used pasteurized egg whites.
When you are ready to use the icing again, bring it back toward room temperature and give it a slow stir with a spatula. If it feels looser than before, whisk in a spoonful of powdered sugar. If it feels thicker, stir in a few drops of water.
Do not leave raw egg white icing at warm room temperatures for long stretches, especially in summer kitchens. For bake sales and long events, many bakers prefer icings based on meringue powder because they tolerate time on the table better.
When Egg White Sugar Icing Is A Good Choice
This two-ingredient icing shines when you want clean lines, a matte candy shell on cookies, and a short ingredient list. It is perfect for sugar cookies, gingerbread houses, and small cakes where decorations need to hold their shape overnight.
On the other hand, buttercream or cream cheese frostings suit layer cakes that need a softer bite and a thicker layer of topping. If you love the look of royal-style decorations but want less risk for children or people with health concerns, try the same ratio style with pasteurized liquid egg whites or meringue powder instead of raw shell eggs.
With a little practice, how to make icing using egg white and sugar only stops feeling like a last-minute fix and turns into a reliable part of your baking routine. Once you know how the ratio, texture, and drying time behave in your kitchen, you can whip up glossy lines and crisp details whenever you need them, using nothing more than eggs, sugar, and a bit of patience.
