If you have ever looked at a leftover jar of sauerkraut in the fridge and thought, “There has to be a better plan than hot dogs,” welcome. This is that plan.

Chocolate sauerkraut cake is an old school Midwest and church cookbook classic for a reason. The sauerkraut melts into the crumb, bringing moisture and a gentle tang that makes the cocoa taste deeper and more chocolatey. Think buttermilk vibes, not deli counter vibes.

This one is perfect for cold weather potlucks, holiday dessert tables, and any week where you want a chocolate cake that stays soft for days. Also, it is an elite “guess the secret ingredient” party trick.

Why It Works

  • Deep chocolate flavor: Cocoa plus hot coffee blooms the chocolate and makes the cake taste bakery-level without fancy ingredients.
  • Moist, tender crumb: Sauerkraut holds onto moisture like a champ, so the cake stays plush instead of drying out on day two.
  • Balanced sweetness: The slight tang keeps the whole thing from going flat and sugary.
  • Easy technique: One bowl for dry, one for wet, then fold in the chopped kraut and bake. No drama, no special equipment.

Storage Tips

Room temperature: If the cake is unfrosted, wrap it tightly and keep it at room temp for up to 2 days.

Refrigerator: If you use the ganache or any dairy-based frosting, store covered in the fridge for up to 5 days. Let slices sit out 20 to 30 minutes before eating so the crumb softens and the chocolate flavor pops.

Freezer: Freeze unfrosted slices or the whole cake layer wrapped in plastic wrap and then foil for up to 2 months. Thaw overnight in the fridge or for a few hours at room temp.

Pro tip: If the ganache gets too firm in the fridge, a 10 second microwave zap on an individual slice brings it back to glossy and decadent.

Common Questions

Will this cake taste like sauerkraut?

No. The cake tastes like chocolate cake. The sauerkraut mainly adds moisture and a subtle tang that reads like “wow, this is rich” rather than “this is fermented cabbage.”

Do I need to rinse the sauerkraut?

Yes, rinse it well and drain it very well. Rinsing removes excess brine and salt so the cake stays balanced. Then squeeze it dry in a clean towel or paper towels. You want it damp, not dripping.

Do I need to chop the sauerkraut?

Yes. After rinsing and squeezing, finely chop it so it melts into the crumb instead of baking up in long, stringy shreds. This is the difference between “secret ingredient” and “wait, what is that texture?”

How much sauerkraut should I use?

Measure after it is rinsed, drained, squeezed, and finely chopped. You want about 1 cup, tightly packed. That usually comes from a 14 to 16 ounce jar once prepped.

What kind of sauerkraut works best?

Plain, unflavored sauerkraut. Avoid caraway-heavy, wine-infused, or spicy versions. Refrigerated or shelf-stable both work, as long as it is rinsed, squeezed dry, and finely chopped.

Can I make this in a 9x13 pan?

Yes. Bake at 350°F and start checking around 30 minutes. It usually finishes around 35 to 40 minutes depending on your pan and oven.

Can I skip the coffee?

Absolutely. Use hot water instead. Coffee does not make it taste like coffee, it just boosts the chocolate.

Why is my cake dense?

Most common causes are overmixing after adding flour, packing flour into the measuring cup, or using too much sauerkraut. Measure the sauerkraut after squeezing and chopping, mix gently, and stop as soon as the batter comes together.

The first time I heard “chocolate sauerkraut cake,” I laughed like it was a prank someone pulled at a potluck. Then I tasted it and had that mid-bite pause where your brain does the math and goes, “Okay, wow. That is actually incredible.”

Now it is one of my favorite cold-weather desserts because it feels both cozy and mischievous. You get a legit chocolate cake with a glossy top, and you also get to casually say, “Yeah, there is sauerkraut in it,” and watch everyone spiral for a second. The best part is it is not a gimmick. It is just a smart old trick that still works.
