What Is Flourless Chocolate Cake?

Flourless chocolate cake is made using a combination of cocoa powder and butter or oil mixed with eggs and sugar. This magical chocolate custard is aerated to create a dense yet moist texture that will leave you wanting more. The first documentation of this cake was found in Ferrara, Italy.

You can also add customized ingredients such as fresh fruit, nuts, or your favorite liqueur for a more flavorful experience!


Now that you know how to make a delicious keto-friendly flourless chocolate cake, it's time to get into the ingredients! To get started, you'll need the following:

  • 8oz dark chocolate, chopped

  • 1/2 cup butter, cut into pieces

  • 1 cup keto sweetener (I used Splenda)

  • 5 eggs, separated

  • 1/2 teaspoon salt

  • 2 teaspoon vanilla extract

  • 1 Tbsp cocoa powder


  1. Preheat your oven to 325 degrees Fahrenheit, and grease an 9" springform pan with butter. Dust with cocoa powder

  2. Melt the dark chocolate and unsalted butter in a microwave at 30-second increments until smooth and creamy. Set aside to cool slightly.

  3. Separate eggs and place egg whites into a stand mixer. Set aside yolks for later. Gently whisk the egg whites on medium and gradually add in sugar until stiff peaks form.

  4. Add egg yolks, vanilla extract, and salt into the chocolate mixture and combine.

  5. Slowly fold in the melted chocolate mixture into the egg whites and fold until everything is fully incorporated and smooth in texture. Make sure there are no white or chocolate streaks.

  6. Pour the batter into your greased baking pan and spread it evenly with a spatula or spoon.

  7. Bake for 45-60 minutes, or until a knife comes out clean.

  8. Let it cool completely before removing from pan.

Top with powdered sugar, whipped cream, or fresh berries.

Tips and Tricks for The Perfect Cake

Whipping the Egg Whites

Whipping the egg whites is crucial to getting a light and fluffy texture that you want in a chocolate cake. Whip them on medium using the whisk attachment to your stand mixer. Keep an eye on them to not have them get too stiff. But when the egg whites start to peak and it holds, you're ready to continue!

Use Unsweetened Cocoa Powder

One way to ensure that your Keto-Friendly Flourless Chocolate Cake will be keto-friendly is by opting for unsweetened cocoa powder. This way, you can control the amount of natural sweetener you use and make sure it stays within keto guidelines. Original Hershey's cocoa powder works best!

Fold Carefully

When folding in the egg whites, be sure to do it carefully and slowly so as not to knock out all of their air. This will help keep your cake light and fluffy! A silicone spatula will help easily fold your ingredients without losing the air!

Stick with these simple tips and tricks, and you’ll be well on your way to making an incredibly delicious Keto-Friendly Flourless Chocolate Cake!
