An easy keto chocolate cake that is only three ingredients and takes less than five minutes to prepare. This low carb and keto-friendly cake doesn’t require any special flours. It is rich, chocolatey and makes an indulgent dessert.
I love how quick and easy this keto cake is. It’s easy enough that you can make it whenever you have a chocolate craving. You can also dress it up for a special occasion.
What I love best is that you don’t need any special flours like almond flour or coconut flour. It’s flourless so it’s easy to make when you want a single-serving cake. If you are following keto, you should definitely try this low carb chocolate cake.
Ingredients
- Egg
- Unsweetened Cocoa Powder
- Erythritol Granular
You can use either Dutch process cocoa powder or natural cocoa powder. I prefer Dutch process because I think it has a richer chocolate taste.
You can substitute erythritol granular with any other granular sweetener.
How to Make It
You will need 5-ounce ramekin for this recipe. Grease it with butter or cooking spray.
Whisk the egg in a medium bowl for one minute and then whisk in the cocoa powder and erythritol.
Pour the cake batter into the prepared ramekin. Bake it for 20 to 25 minutes or until the bounces back when you lightly press the top. You can check with a toothpick, too – it should come out clean.
Allow the cake to cool for at least 15 minutes or so before eating it.
Recipe Notes
Beating the Egg
Unlike most flourless cakes, this one doesn’t require you to separate the egg white from the egg yolk. However, you do need to thoroughly beat the egg. I recommend beating vigorously and continuously for one full minute. When you are done, you should not see any egg white streaks. Beating the egg this long adds air and volume to the egg, which helps the cake rise (since there is no rising agent in this recipe).
Cake Texture
This cake is similar to other flourless cakes in that it has a very tight crumb since there is no flour. The cake will not rise as high and so it appears small, but it is very rich and filling.
Topping Ideas
I love to serve this cake warm (though it can also be eaten fully cooled). You can serve it with
- a scoop of keto-friendly ice cream
- low carb chocolate sauce
- powdered sweetener
- fresh berries (like strawberries, raspberries or blueberries)
This keto chocolate cake recipe definitely cures a chocolate craving. I love that it’s so easy to make and only makes one serving. I hope you try it soon!

3 Ingredient Keto Chocolate Cake
Ingredients
- 1 large egg
- 1 ½ tbsp (11 grams) unsweetened cocoa powder
- 2 tbsp (24 grams) erythritol granular
Instructions
- Preheat oven to 350°F. Lightly grease a 5 oz ramekin with cooking oil spray.
- Add the egg to a medium bowl. Using a mini whisk, beat vigorously for 1 full minute. This ensures the egg is fully beaten and adds some volume to the egg which will help make the cake rise.
- Add in cocoa powder and erythritol. Whisk until batter is smooth.
- Pour batter into prepared ramekin. Bake for 20-25 minutes or until cake puffs up and when you apply pressure to the surface, the cake bounces back and doesn't sink in. Toothpick inserted should come out mostly clean.
- Let cake cool for about 15-20 minutes before serving.
Notes
- Erythritol granular can be replaced with other granular sugar substitutes like Swerve or Lakanto monkfruit sweetener.
- I used So Nourished erythritol sweetener granular*

Hi Kirbie, will Stevia work for the sweetener?
Any granular sweetener should work.
Can you please convert this for a 9 inch cake pan? I don’t know if I should multiply quantities by 6 or what. Thanks.
Sorry, but without testing it we can’t say how the recipe needs to be adjusted.
Just made it…great recipe, delicious.
Thanks for letting us know – so happy you loved it!
I put the ramekin on a rack in my air fryer, preheated to same temperature, “Bake” setting… 10 or 11 minutes seems to do it. 🙂
