Souffle cakes, also known as fallen cake or sunken cake, are easy to make and ideal for the home baker that stresses when decorating or frosting cakes. They puff up during baking and then the top naturally caves in creating a crackly look.

This type of flourless chocolate cake is perfect for Christmas, Valentine’s Day, a birthday, or literally any special occasion if you’re craving something simple and decadent.

📖Why This Recipe Works

First off, this recipe uses two types of chocolate. The combination of melted dark chocolate and cocoa powder creates the richest, most chocolatey flavor.

Next, we add espresso powder. A couple of teaspoons of instant espresso powder enhances the floral notes in the chocolate. You can’t taste any coffee, but it gives the cake a better flavor!

This recipe is flourless which makes this cake gluten-free, but also creates such a light, airy texture!

That is where our whipped egg whites come in. Egg whites are whipped to incorporate air into the batter. The air causes the cake to rise in the oven, then collapse when it’s taken out. This gives it that cracked top and crispy edges.

🧾Ingredient Notes

Bittersweet Chocolate - Use blocks or bars of chocolate that are 65% cacao or higher. The richer chocolate creates the best flavor and texture. I don’t recommend using semi-sweet chocolate chips. They will make the cake much too sweet and the texture won’t be as smooth.

Cocoa Powder - I use Dutch-processed cocoa powder because it tends to have a smoother, more chocolatey flavor. If all you have is regular, that will work too.

Instant Espresso Powder - Espresso powder is used to enhance the chocolate flavor of the cake. Don’t worry. It won’t make your chocolate cake taste even one bit like coffee.

Eggs -This recipe separates the whites and the yolks, except for 1 egg which we add whole. All my recipes use large eggs.

Cream of Tartar - Cream of tartar helps to stabilize the egg whites but is optional.

Unsalted Butter - You can use salted butter, but will want to adjust the amount of salt you add yourself.

You will also need white sugar, salt, and vanilla extract.

⏲️How to Make Chocolate Souffle Cake

Before starting on the batter prepare your cake pan and preheat the oven to 325 F degrees.

Butter or grease the inside of your pan and then dust the pan with cocoa powder (my preference) or sugar.

Step 1 - Melt the Chocolate

A double boiler is a two-tiered pan, but you can make one with a small saucepan and a small heatproof bowl set on top. Fill the saucepan with at least 1 inch of water, you don't want the water to touch the bottom of the bowl.

Place the bowl on top of the saucepan and heat over medium heat. You want simmering water, not boiling.

Add the chocolate and butter to the mixing bowl. Stir frequently melted. Remove the bowl from the heat. set aside to cool slightly.

Step 2 - Egg Yolk Mixture

Separate the egg whites and yolks, then place the yolks into a large bowl and the egg whites into another clean mixing bowl, and set the egg whites aside.

Add the whole egg and one-third of the sugar to the egg yolks. Beat on medium-high speed until thickened. This typically takes 5 minutes. The egg yolks are ready when the mixture creates thick ribbons when the beaters are removed.

Add in vanilla, salt, cocoa powder, and espresso powder, then mix again until incorporated.

Slowly add the cooled chocolate to the egg yolks and stir until combined. If the chocolate is too hot the eggs will scramble.

Step 3- Whip Egg Whites

In an electric mixer, use a clean whisk attachment to whip the egg whites with cream of tartar. Gradually add the remaining sugar, then beat on high until medium-stiff peaks form.

Some recipes call for soft peaks but I find that will knock too much air out when folding into the chocolate batter.

Use a spatula to gently fold in half of the egg whites until they begin to incorporate. Add the rest of the egg white mixture, being careful not to over-mix. There may be some white streaks- that is perfectly normal.

Step 4 - Bake

Transfer the batter to your pan. Use a small offset spatula to carefully smooth out the top. Bake for 45 to 50 minutes. You can check with a knife, but I prefer not to damage the top of my cake.

Cool completely before removing it from the pan and transferring it to your serving plate.

Serve topped with a dusting of powdered sugar, cocoa powder, or whipped cream. If you are feeling fancy, you can add creme anglaise, fresh raspberries or sliced strawberries.

Expert Tips

  • Use a springform pan. A springform pan makes it so much easier to remove the cake without damaging it.
  • Eggs separate easiest when cold but the whites will whip better at room temperature.
  • Grease and dust the pan. I coat the inside of the pan with butter and sugar or cocoa powder. This adds a little extra flavor and crispiness to the outside of the cake and helps prevent it from sticking.
  • Make sure you use a double boiler to melt the chocolate to prevent it from burning! If you melt the chocolate in the microwave, do so at 50% power to prevent it from seizing up.
  • Don’t over-mix. That can cause the cake to be dense. We want it to be light and fluffy so it rises in the oven and falls when you take it out.
  • The cake is done when the edges of the cake are pulling away from the sides of the pan. This should take right around 45 minutes, but I recommend checking early, then adding time as needed.
  • Cool first. Let the cake cool completely before you remove it from the pan and dig in. It needs a little bit of time to set up in the pan after baking.

This chocolate souffle cake is so creamy and soft in the middle, so I like to store it at room temperature if possible. It will last covered for 2-3 days.

I don't recommend freezing this cake.

💬Frequently Asked Questions

What is the difference between a souffle and a cake?

A souffle is a type of cake, but it’s made using a slightly different process than that of a regular cake. To make a souffle cake, you separate the yolks and whites of the eggs and whip the egg whites to stiff peaks.

This adds air to the batter which causes the cake to rise in the oven, then collapse in the center when it’s taken out. Souffle cakes use very little flour or no flour at all.

What does souffle cake taste like?

The perfect chocolate souffle has a rich, but not too sweet, chocolatey flavor, a slightly dry top, crisped edges, and a soft, creamy interior.

And that, my friends, is exactly what we’re getting in this recipe. It’s a chocolate lover's dream, it so delicious!

  • The top of the cake will fall creating a crackly top. The top should be slightly dry and the interior creamy.
  • This cake needs to be baked in a springform pan if you want to serve it on a platter. It can't be turned out on to a cooling rack like a standard cake.
