Magic Cake

Magic cake, or gateau magique, is a delicate French dessert that impresses at every level. Baked in a single pan, the batter produces three different layers while in the oven, earning the cake its name to the delight of many bakers and dessert lovers.

Although it looks stunning, it requires only a few simple ingredients—eggs, milk, brown sugar, butter and flour—and it’s quick and easy to assemble. And thanks to the surprising cake layers produced, it’s ideal for any occasion, whether you need a quick treat at home or are taking dessert to a potluck.

What is magic cake?

This classic French dessert gets its name from the way three layers are produced while it is baking, without the baker having to layer the batter or put together separate layers of baked cake. It’s just like magic—and it reminds us a lot of a Dutch funny cake.

Magic cake’s distinct structure creates a firmer custard-like bottom layer, a soft and creamy middle layer, and an airy sponge on top. Take this advice from the recipe developer Margaret Knoebel: “Many steps of this cake go against all the baking rules. Don’t be scared when the batter is thin or there are lumps of egg white, it will all turn out to a delicious cake!” The overall texture is light, with a simple flavor and just a hint of brown sugar. It’s delicious served chilled or at room temperature on its own, or top the cake with berries and confectioners’ sugar.

Ingredients for Magic Cake

• Brown sugar: Brown sugar adds just a touch of sweetness and a depth of flavor. Use light or dark brown sugar; dark brown sugar adds more molasses flavor.
• Eggs: Eggs are key to making this magic cake recipe. You’ll need four eggs at room temperature. Separate the eggs while they’re still cold to make the process simpler.
• Whole milk: Milk adds moisture and enhances the rich flavor and texture.
• Butter: Melt a stick of butter and let it cool to incorporate it into the batter.
• Vanilla bean paste: Vanilla bean paste adds incredible flavor to enhance the cake. If you don’t have vanilla bean paste, use 1 teaspoon of pure vanilla extract instead.
• All-purpose flour: A small amount of flour goes a long way to provide structure for this magic cake recipe.
• Confectioners’ sugar: Dust this cake with confectioners’ sugar for a touch of extra sweetness and a beautiful presentation.

Directions

Step 1: Prepare the pan

Preheat the oven to 325°F. Grease a 9-inch square pan and line it with parchment.

Step 2: Start the batter

In the bowl of a stand mixer, using the whisk attachment, whisk the brown sugar and egg yolks until light and foamy, five to six minutes. Add the milk, melted butter and vanilla bean paste until well combined (the mixture will be thin).

Sift in the flour.

Step 3: Beat and add the egg whites

In a separate bowl, with clean beaters, whisk the egg whites to stiff peaks. Fold the egg whites into the batter (mixture may still have lumps).

Editor’s Tip: Whip the egg whites long enough to reach the proper texture. Here’s how to tell the difference between soft peaks and stiff peaks.

Step 4: Bake the cake

Pour the batter into the prepared pan.

Bake until golden brown and puffed, 40 to 45 minutes. Remove the cake to a wire rack and let it cool to room temperature.

Step 5: Chill and serve

Refrigerate until chilled, for four hours or overnight. If desired, garnish with confectioners’ sugar before slicing and serving.

Magic Cake Variations

• Add other flavorings: Vanilla bean paste adds wonderful flavor to this recipe for magic cake, but you can use other flavorings. Incorporate 1 teaspoon of almond extract or fold in fresh fruit zest, such as lemon or orange zest.
• Try different toppings: Dress up this magic cake with a topping. Add a dollop of whipped cream to each serving, or make chocolate ganache and spread it over the top.
• Serve with fruit: Berries are the perfect match for this magic cake. Add fresh blueberries or raspberries on top, or pair it with a blueberry sauce.

How to Store Magic Cake

Cover the magic cake well with storage wrap and store it in the refrigerator for up to three days.

Can you freeze magic cake?

Because of its custard-like texture, magic cake does not freeze well. It is best to enjoy it out of the refrigerator within three days of making it.

Magic Cake Tips

Can you make a magic cake in a different-sized pan?

It’s important to make this recipe in the correct pan size. Using a 9-inch square cake pan with high walls is crucial to provide support and help set up your layers for success.

How do you know when your magic cake is done baking?

The cake certainly needs a while to bake, and it’s best to leave it in the oven longer than to take it out early. The top will slightly jiggle and should be golden brown before removing the cake from the oven. It may not look like much straight out of the oven, but as the cake cools and settles, the layers will become more pronounced.

Do you have to refrigerate magic cake?

This custard-based cake should be refrigerated. You can serve it cooled to room temperature right after baking or chilled straight out of the refrigerator.
