WHY YOU WILL LOVE THIS RECIPE

Simple ingredients - all you need are 5 basic ingredients to make this and you probably already have them handy.
No flour - this cake doesn't contain any flour at all. In the absence of flour, this cake gets its structure from two main ingredients: eggs and chocolate. Egg proteins provide strength. The yolks help emulsify the chocolate with the liquid from the whites, while the whipped proteins from egg whites provide majority of the structure and add lift to give this cake it's light and airy texture.
Rich chocolate flavor - this recipe is based on dark chocolate. Dark chocolate has a high cocoa content which provides some starchy compounds that will support the batter. Cocoa butter is also very hard at room temperature and will firm up to set the structure of this cake.
Soft, melting texture - the texture of this cake is so unbelievable that it's almost hard to explain. It is dense and rich, yet light and soft. It literally melts in your mouth and then there's a slightly crisp flaky crust on top for extra texture.

INGREDIENTS

Here are some notes about the ingredients. For a full recipe with measurements, scroll down to the recipe card at the bottom of the page.

Eggs - five whole large eggs will set the structure of this cake.
Brown sugar - light brown sugar will keep this cake sweet and moist and help the eggs whip up thick and creamy.
Butter - I use salted butter for it's richness, and it means you don't need another ingredient (salt!). You can use unsalted butter if you don't have salted butter. In this case, you'll need to add ⅛ teaspoon of salt into the batter.
Dark chocolate - you'll need pure dark chocolate to make this cake - compound chocolate will not work. It is important that the chocolate has a high cocoa content as well, since the cocoa and cocoa butter will firm up this cake. If you use semi-sweet chocolate, it will contribute a lot more sugar and it will affect the final texture of the cake. I highly recommend dark chocolate with 60% cocoa solids. You can blend semisweet chocolate with my favorite bittersweet chocolate callets which are very convenient.
Cocoa powder - get your hands on some good quality cocoa powder! Chocolate is the main flavor and you want it to shine so use the best you can find. I love to use this Dutch Process cocoa powder for this recipe. Make sure you use unsweetened cocoa powder and not cocoa mix.

STEP BY STEP INSTRUCTIONS

STEP 1). Melt butter with chocolate. Combine chopped chocolate and butter in a saucepan and place it over very low heat. Stir constantly until completely melted and smooth. Set aside to cool for 10 minutes.
STEP 2). Whip the eggs. Use a stand mixer or a hand mixer to beat the eggs for 5 minutes. Then gradually beat in the sugar just 1 tablespoon at a time. Beat until very pale and thick. It should triple in volume and take almost 7 minutes. This is called the "ribbon stage" when the whipped eggs fall off the beater back onto itself in pillowy folds.
STEP 3). Add chocolate to eggs. Gently fold the cooled chocolate mixture into the whipped eggs.
STEP 4). Add cocoa powder. Sift in the cocoa powder and then keep folding gently to combine.
STEP 5). Bake. Pour the batter into the prepared pan and bake!

EXPERT BAKING TIPS

Making this cake is so quick - it takes just about 10 minutes! There are two main processes for making it: the chocolate base and the whipped eggs. Here are tips to ensure you make the best flourless chocolate cake...

Cool the chocolate mixture - If the chocolate is too hot, it will deflate the eggs when they are folded in. Having a cooled chocolate base will help stabilize the structure.
Slowly beat in sugar - adding the sugar gradually will ensure that the eggs whip to their maximum volume. If it is added all at once it will deflate them. Gradual addition also gives the sugar a chance to dissolve in the eggs which will create a more moist texture and a stable foam.
Be gentle - Fold the whipped eggs into the chocolate mixture gently. Use a large flat rubber spatula for big surface area to pick up batter from the bottom and fold it through and over the top. If you fold too vigorously, the air bubbles will deflate.

RECIPE FAQ

What type of chocolate is best for flourless chocolate cake?

Since chocolate is the main ingredient in this cake, it is very important to use a good block. Bittersweet chocolate with 70% cocoa solids is ideal, but anything over 60% cocoa will work. I would avoid using chocolate chips unless you have bittersweet chips because most chocolate chips have a lower cocoa content and much more sugar.

What pan is best to bake flourless chocolate cake?

The easiest way to bake this flourless chocolate cake is with a springform pan lined with parchment paper on the base because it allows for easy release.
This cake is very delicate so turning it out would risk break it, hence why a pan with removable sides is idea.

How do I know when flourless chocolate cake is baked to perfection?

When this cake is ready, it will puff up and start to crack a bit in the center. It will feel a bit firm, but I promise it will be so soft inside. Give the pan and little nudge and it should still jiggle a bit. When you take the cake out of the oven, it will start to deflate and that is totally what it is supposed to do! It will have a beautiful soft texture inside. Let it cool completely before slicing and use a hot dry knife.

What can I serve with flourless chocolate cake?

This cake is so delicious on its own, but there are a few things you could do to jazz it up: a simple dusting of cocoa powder or icing sugar, a dollop of lightly sweetened whipped cream with a few fresh berries, or a dollop of Greek yogurt and a drizzle of honey.

How do I store flourless chocolate cake?

If you plan to keep this cake for just a day or two, you can leave it at room temperature in an airtight container. That's assuming you don't live in a very hot humid climate. If you happen to have any leftovers (ours never lasts longer than 2 days!), it's best to keep it in an air tight container in the fridge. It will keep there for up to 5 days. When you want to serve it, you can either eat it chilled or let it come to room temperature first.

Servings 10 servings

Ingredients

8 oz (227g) dark chocolate (60-70% cocoa solids)
½ cup (113g) salted butter
5 large eggs, at room temperature
⅔ cup (145g) packed light brown sugar
3 tablespoon (18g) cocoa powder (I prefer this one)

Instructions

Preheat oven to 350°F. Lightly grease the sides of an 8-inch round non-stick springform pan with butter and line the base with a round of parchment paper.
Coarsely chop the chocolate and place it in a saucepan with the butter over very low heat. Stir constantly until completely melted and smooth, being sure not to burn it. Set aside to cool.
Place eggs in the bowl of a stand mixer fitted with the whisk attachment and beat for 1 minute on high speed until very foamy. Gradually add sugar one tablespoon at a time and continue to beat for 6 minutes longer on medium-high speed until very pale, thick and voluminous. Slowly dribble in the melted chocolate mixture bit by bit while folding gently by hand with a wide spatula. Pause to sift in the cocoa powder and then continue folding gently until evenly combined. Reach down to the bottom of the bowl to lift up the dense chocolate mixture that can sink to the bottom. Try not to over-mix as it will knock the air out of the batter.
Pour batter into a prepared pan and then place the pan onto a rimmed baking tray. Bake for about 30 minutes until the cake is puffed and slightly cracked on the surface. It will look dry and feel a bit firm, but trust that it will be tender. Transfer cake pan out onto a wire rack to cool completely.
Run a knife around the edges of the pan and gently release the sides. Dust with cocoa and serve with whipped cream if desired. This cake is best served at room temperature. Slice with a hot dry knife.
