Chocolate Ice Box Cake

Old-fashioned no-bake chocolate icebox cake from the era when the refrigerator did all the work. Melted German sweet chocolate gets mixed with powdered sugar and beaten egg yolks to form a rich custard, then folded with whipped cream and beaten egg whites for a mousse-like texture that’s impossibly light.

Torn pieces of angel food cake get layered with the chocolate custard in a pan, then the whole thing chills overnight. During those twelve hours, the custard soaks into the spongy cake pieces, softening them into something that’s part pudding, part truffle, part cloud.

Breaking the angel food into irregular pieces is intentional. Uniform slices would create distinct layers, but jagged, torn bits create pockets where the chocolate custard seeps into every crevice.

Pro Tips

• Melt the chocolate slowly with the boiling water, stirring constantly. Chocolate seizes if it gets too hot too fast.
• Beat the egg whites to moderately stiff peaks, not bone dry. Overbeaten whites are harder to fold smoothly and can leave streaks.
• Give it the full twelve hours. Shortcuts here mean a dry, crumbly cake instead of that signature fudgy texture.
• Use a glass dish so you can see the layered chocolate and cake from the side when serving.

Variations

• Use ladyfinger cookies or vanilla wafers instead of angel food cake for a firmer texture.
• Fold crushed peppermint candy into the custard for a chocolate mint version.
• Top with shaved chocolate curls or cocoa powder before serving.
