There is something a little magical about a cake that is essentially sweetened air. National Angel Food Cake Day, celebrated every year on October 10, honors one of baking’s great feats of physics: a tall, snow-white cake that gets its lift from nothing but whipped egg whites, with no butter, no oil, and no egg yolks at all.
What it’s all about
Angel food cake is built from a short list of humble ingredients: egg whites, sugar, flour, and a little cream of tartar and vanilla. What makes it special is technique rather than richness. When you beat egg whites, you trap thousands of tiny air bubbles in a protein network; sugar stabilizes that foam, and gentle folding of flour keeps it intact. In the oven the trapped air expands, and the cake rises into a springy, cloudlike sponge. Because it contains no fat, it is famously light, both in texture and on the conscience.
A little history
The cake as we know it took shape in the United States in the late nineteenth century, and it spread quickly once affordable tube pans and rotary egg beaters reached home kitchens. Its ethereal color and weightlessness earned it the “angel” name, and it became a natural companion to another egg-heavy cake, the golden sponge, which thriftily used up the leftover yolks. For a long time it was a showpiece dessert precisely because whipping all those whites by hand was real labor.
A good angel food cake should feel almost too light to be real, tearing into soft, cottony strands rather than slicing like a pound cake.
How to make the most of it
October 10 is a fine excuse to attempt one yourself, and the payoff is high for a cake with so few ingredients. Start with room-temperature egg whites and make absolutely sure your bowl and beaters are spotlessly clean, because even a trace of grease or yolk will keep the whites from whipping. Beat to soft peaks, add sugar gradually, then fold in the sifted flour with a light hand. Bake in an ungreased tube pan and cool it upside down so it does not deflate.
If baking from scratch feels ambitious on a weeknight, a boxed mix or a store-bought cake still gives you plenty to work with. Angel food shines as a base: split it into layers and fill it, cube it for a trifle, or grill thick slices for a minute until the sugar caramelizes at the edges. Serve it with macerated berries and whipped cream, a pour of lemon curd, or simply a dusting of powdered sugar. However you enjoy it, take a moment on October 10 to appreciate a dessert that proves you can turn egg whites, sugar, and flour into something that genuinely tastes like a cloud.
How to celebrate
- 1Whip whites to soft peaks
Angel food cake rises on egg whites alone, so beat them just to soft, droopy peaks before adding sugar, not stiff and dry. Room-temperature whites whip fuller and more stably than cold ones, so pull your eggs out 30 minutes ahead. A pinch of cream of tartar helps the foam hold its structure.
- 2Fold, never stir
Once the flour and sugar are sifted, fold them in with a spatula in gentle strokes, cutting down through the center and lifting up around the edge. Stirring or beating knocks the air out and leaves you with a dense, rubbery cake. Add the dry mix in three additions so it incorporates without deflating the batter.
- 3Use an ungreased tube pan
Counterintuitively, you want a clean, ungreased aluminum tube pan so the batter can climb and grip the sides as it bakes. A nonstick or buttered pan gives the cake nothing to hold onto and it collapses. Invert the pan immediately after baking and let it cool completely upside down so the airy crumb sets without sinking.
- 4Top it simply
Angel food cake is a blank, lightly sweet canvas, so skip heavy frosting. Macerate sliced strawberries with a spoonful of sugar for 20 minutes until they release syrup, then pile them on with softly whipped cream. A drizzle of lemon glaze or a scoop of sorbet also plays well against the cake's cloudlike texture.
