You’re standing in your kitchen, the cake is cooling on the counter, and you realize the pantry is bare. No powdered sugar. Not even a dusty half-bag tucked behind the flour. Most people think they're stuck. They assume you can't get that silky, pipeable finish without that white, cornstarch-laden dust we call 10X sugar. But honestly? Professional pastry chefs often avoid the boxed stuff anyway. It's too sweet. It tastes like chalk.
Getting icing recipes without confectioners sugar to behave isn't just a backup plan; it's a way to level up your baking game. We are talking about old-school French techniques, stovetop miracles, and using literal grains of sand—granulated sugar—to create something that doesn't grit between your teeth. It’s about science. It's about heat. It's about making sure your guests don't leave with a sugar headache.
The Granulated Problem and the Ermine Solution
If you just toss regular sugar into butter, you get gritty frosting. It’s gross. Nobody wants to eat sand-butter. The trick is dissolving that sugar before it ever touches the fat. This is where the "Ermine" frosting—also known as boiled milk frosting—comes in.
Before the mid-20th century, this was actually the standard frosting for Red Velvet cake. You whisk flour and sugar together, then cook it with milk until it turns into a thick, pudding-like paste. You have to let it cool completely. Like, totally cold. If it’s even slightly warm, it’ll melt your butter and you’ll end up with a greasy soup. Once it’s cold, you beat it into softened butter. The result is surprisingly light. It’s almost like whipped cream but stable enough to sit out on a dessert table for hours. It’s weirdly magical because it uses basic pantry staples and zero "special" sugars.
Why Flour Works
The starch in the flour acts as a stabilizer. It’s basically doing the job that cornstarch does in commercial powdered sugar, but you’re cooking it out so there’s no raw flour taste. If you've ever had a roux-based sauce, you know how thick things can get. This is the sweet version of that.
Going European: The Meringue Method
If you want to feel like a pro, you skip the flour and go for eggs. Specifically, egg whites. This is the world of Italian and Swiss Meringue Buttercreams. These are the gold standard for icing recipes without confectioners sugar because they rely on a hot sugar syrup or a double-boiler method to melt granulated sugar into a cloud of protein.

Swiss Meringue is the more approachable one. You put your egg whites and granulated sugar in a bowl over simmering water. You whisk until the sugar is dissolved—you can literally feel it with your fingers to make sure there’s no grit—and then you whip it into a stiff meringue. Then comes the butter. Tons of it. It’s silky. It’s stable. It’s what those fancy wedding cakes are actually made of.
Italian Meringue is the "final boss" version. You boil sugar and water to the "soft ball" stage ($118^\circ C$ or $245^\circ F$ if you’re being precise) and stream it into whipping egg whites. It’s terrifying the first time you do it. Hot syrup flying everywhere is no joke. But the stability? Unmatched. It won't melt in a warm room as easily as American buttercream.
The Science of Dissolving
Sugar is a crystal. To get it smooth without grinding it into a powder, you need heat and moisture. In these meringue recipes, the water in the egg whites (which is about 90% of an egg white) provides the solvent. Heat provides the energy to break those crystal bonds. Once they're broken, they stay broken as long as you don't let the syrup crystallize on the side of the pot.
The Blender "Cheat"
Can you just make your own powdered sugar? Sorta. If you have a high-powered blender like a Vitamix or a Nutribullet, you can dump in granulated sugar and pulse it.
It gets dusty. It gets messy.

However, it’s rarely as fine as the store-bought stuff. Commercial manufacturers use massive industrial mills to get that 10-micron particle size. Your blender is trying its best, but it might still feel a little "textured." If you go this route, add a teaspoon of cornstarch for every cup of sugar. It prevents clumping. It’s a solid fix for a midnight baking emergency, but it's not the "purest" way to find icing recipes without confectioners sugar if you’re looking for a flavor upgrade.
Cream Cheese and Brown Sugar: The Dark Horse
Most people think cream cheese frosting requires a mountain of powdered sugar to hold its shape. Not necessarily. You can use honey or maple syrup if you’re willing to accept a softer, glaze-like consistency. But if you want a "real" frosting, try using brown sugar.
Brown sugar has molasses in it. It’s acidic. When you beat brown sugar with cream cheese, the grit dissolves into the moisture of the cheese much faster than it does in butter. It creates a caramel-colored, deep-flavored frosting that is unbelievable on spice cakes or carrot cakes.
- Beat the cream cheese and brown sugar first.
- Let it sit for 10 minutes so the sugar can dissolve.
- Beat it again until smooth.
- Add your butter and vanilla last.
It’s dense. It’s rich. It’s definitely not for piping delicate flowers, but for a sheet cake? It’s king.
The Dairy-Free Path: Coconut Cream and Honey
Sometimes you aren't just out of sugar; you’re looking for something "cleaner." Chilled coconut cream (the thick stuff at the top of the can) can be whipped exactly like heavy cream. If you sweeten it with honey or agave, you have a frosting that is technically a "whole food" version.

The catch? It has to stay cold. Coconut fat melts at a very low temperature. If your kitchen is 80 degrees, your frosting is going to be a puddle in twenty minutes. It’s a high-maintenance choice, but for someone avoiding refined sugars and cornstarch, it’s a lifesaver.
What Most People Get Wrong About Texture
Temperature is everything. Honestly, 90% of frosting failures have nothing to do with the sugar and everything to do with the butter. If your butter is too cold, it won't emulsify with the sugar or the base. You'll get lumps. If it's too warm, it breaks.
When you're working with icing recipes without confectioners sugar, especially the cooked ones, the "emulsion" is fragile. You are forcing fat (butter) to hold onto water (the milk or egg base). If you see it starting to look curdled or grainy, don't panic. Just keep whipping. Or, if it's too cold, hit the side of the bowl with a hair dryer for thirty seconds. It usually snaps back together.
Flavor Over Sweetness
One of the biggest benefits of these methods is that they actually taste like something. Traditional American buttercream is basically a sugar bomb. It hides the flavor of the butter. When you use an Ermine or a Swiss Meringue, you actually taste the quality of your ingredients. Use the good butter. Use real vanilla bean paste. The lack of powdered sugar means there's no "mask" over the other flavors.
Actionable Steps for Success
- Get a thermometer. For meringue-based frostings, guessing the temperature is a recipe for a flat mess.
- Cool the base completely. Whether it's the flour-milk paste for Ermine or the egg-sugar mix for Swiss, if it's warm, you're doomed.
- Strain your paste. If you make a cooked flour base, run it through a fine-mesh sieve. One tiny lump of cooked flour will ruin the mouthfeel of the entire batch.
- Use the paddle attachment. After you've whipped your meringue or base to the right volume, switch to the paddle. It knocks out the air bubbles and gives you that smooth-as-glass finish.
- Salt is your friend. Always add a pinch of fine sea salt. It cuts through the fat and makes the sugar taste more complex.
If you’ve run out of the blue box of sugar, don't run to the store. Look at your eggs, look at your flour, and try a cooked method. You’ll probably never go back to the gritty, overly sweet stuff again.
