Julia Child’s Chocolate Mousse Cake (2024)

Made with an egg custard and whipped cream and flavored with chocolate, rum, and coffee, this decadent cake is chocolaty perfection — and happens to be gluten-free, with a texture that hits somewhere between a flourless chocolate cake and a cheesecake. This cake is best served at room temperature or just barely warm, and is rich enough that smaller piece might be enough.

Frequently asked questions

What is a chocolate mousse cake?

Most chocolate mousse cakes are actually a traditional chocolate cake layered with chocolate mousse. Julia Child's version is a cake made with a chocolate mousse, which gets its delicate texture by beating eggs and cream until they are light and airy. The cake sinks as it cools after baking for a light but almost fudgy texture.

Notes from the Food & Wine Test Kitchen

After whipping the cream until it has doubled in volume, you want to be careful to make sure it doesn't deflate. To avoid deflating all that air you incorporated into the cream, start by folding 1/3 of the whipped cream into the chocolate mixture. This initial step lightens the batter, so when when fold in the rest of the whipped cream, it retains its airy texture.

This cake is at its most tender and delicious when eaten slightly warm; however, you may cook it even a day or two in advance and leave it in its pan (covered and refrigerated when cool). Place it in a 200°F oven for 20 minutes to warm gently. Loosen edges using a sharp knife if needed and unmold onto a serving platter. A kitchen torch can be used to gently warm bottom of pan further to help cake release, if needed.
