This unconventional combination of sauerkraut in a chocolate cake may seem strange at first, but trust me – it works! The sauerkraut adds moisture and a subtle tanginess to the cake. Don’t let the unusual ingredient discourage you from trying this recipe – no one can tell it’s there. Plus this tender cake is sure to be a hit with all chocolate lovers.
Most keto cake recipes can be dry since the sugar substitutes in the cake batter don’t trap moisture like regular sugar does. In order to balance this, sour cream, yogurt or buttermilk are usually added to sugar free cakes, like in keto spice cake. However, the shredded sauerkraut made from cabbage in this chocolate cake works similarly to carrots in carrot cake. It adds moisture without having to add additional fats. The result is a moist spongy cake!
Top with a creamy, sugar-free buttercream chocolate frosting or make a creamy light chocolate mousse to add on top. The combination will be your new go-to keto chocolate cake recipe!

I was skeptical about using sauerkraut in a cake but it really helped make it super moist. The chocolate flavor was rich and the texture was great. I used coconut flour instead of oat fiber and it turned out fine, though I added a bit more liquid.
This cake turned out moist and surprisingly rich. I was skeptical about the sauerkraut but it blends right in. I didn’t have oat fiber so I used coconut flour instead and it worked fine. Nice option for staying low carb during birthdays.
this recipe calls for oat “FIBER” not ‘FLOUR’ they are different- oat fiber is zero net carbs. Its all fiber. some people choose not to consume oat fiber on the keto diet (because its derived from a grain) but I just wanted to clarify that there is a difference- 😉
Can you use an alternative to the oat flour?
I haven’t tried any substitutions for that yet. But if I were to try, I would sub out the oat fiber for coconut flour. Maybe try 1/4 cup.
