Chocolate-Cinnamon Angel Cake

This angel food cake adds cocoa powder and cinnamon to the classic formula, giving it a flavor profile that leans toward Mexican hot chocolate: warm, spiced, and deeply chocolatey without any fat at all. No butter, no oil, no egg yolks. Just whipped egg whites, sugar, and a triple-sifted dry mix that folds in like a cloud.

The triple sifting isn’t fussiness. Cake flour, powdered sugar, cocoa, and cinnamon need to be perfectly combined and aerated before they go anywhere near the beaten egg whites. Lumps of cocoa or clumps of powdered sugar would deflate the whites on contact, and you’d lose the airy structure that defines angel food cake.

Folding is the make-or-break step. Add the flour mixture in four additions, sifting each portion over the beaten whites and folding gently with a rubber spatula. Cut down the center, sweep along the bottom, fold over. Repeat until just combined. Stop the moment you don’t see dry streaks.

Cool the cake inverted in the pan. If you set it upright, the delicate structure collapses under its own weight before it has time to set.

Chef Tips

• Egg whites must be at room temperature before whipping. Cold whites take longer to whip and don’t reach full volume.
• Beat to stiff peaks (tips stand straight up). Soft peaks won’t support the flour mixture, and the cake will be dense.
• Add granulated sugar gradually, two tablespoons at a time. Dumping it in all at once deflates the whites.
• Use an ungreased pan. The batter clings to the sides as it rises. A greased pan lets it slide down.

Variations

• Add a pinch of cayenne pepper along with the cinnamon for a spicy Mexican chocolate kick.
• Serve slices with a drizzle of chocolate ganache and fresh raspberries.
• Dust with powdered sugar and cocoa powder through a stencil for an elegant finish.
