Before you start
Before beginning, ensure all ingredients are at room temperature to facilitate proper mixing. Prepare your 9x13 inch baking dish by greasing it lightly with butter or non-stick spray to prevent sticking. Have your whisk, spatula, and mixing bowl clean and ready.
Thoroughly rinse the sauerkraut under cold running water in a fine-mesh sieve, then squeeze out as much moisture as possible using paper towels before finely chopping it to ensure it blends perfectly into your cake batter.

- 1 cup sauerkraut, drained and rinsed
- 2 cups prepared chocolate cake batter
- 1 cup fudge icing, store-bought or made ahead
Instructions
Mixing the Batter
- Prepare the BatterRinse the sauerkraut thoroughly under cold water to remove excess brine, then pat it dry and chop it finely. In a large mixing bowl, combine the prepared chocolate cake batter with the finely chopped sauerkraut, folding it in until evenly distributed throughout the mixture.Look for The batter should be dark with tiny, barely visible shreds of sauerkraut evenly incorporated throughout the mixture.Tip Ensuring the sauerkraut is well-drained and finely chopped prevents large chunks in the finished cake texture.
The batter should be dark, glossy, and uniform in texture. Check that the sauerkraut is fully incorporated into the base without any large clumps remaining.
The finely chopped sauerkraut should be evenly distributed throughout the bowl, ensuring every scoop of batter will contain the necessary moisture elements for a consistent bake across the entire pan.
Baking the Cake
- Bake the CakePreheat your oven to 350°F (175°C). Grease a 9x13 inch baking dish and pour the batter into the dish, smoothing the top with a spatula. Bake for 30 to 35 minutes, or until a toothpick inserted into the center comes out clean. Allow the cake to cool completely on a wire rack before applying any frosting.Look for The cake should be firm to the touch, and a tester should come out clean without any wet batter attached.Tip Avoid opening the oven door too frequently during the first 20 minutes to ensure the cake rises evenly.
The cake should have risen evenly and appear firm across the top. The edges should be slightly pulling away from the sides of the baking dish, and the surface should spring back when gently pressed.
Ensure the center is fully cooked and set before removing it from the oven, as the moisture from the sauerkraut requires adequate time to properly stabilize.
Applying the Frosting
- Finish and FrostOnce the cake has cooled completely, spread the fudge icing generously across the surface. Use an offset spatula to create decorative swirls or a smooth finish as desired. Let the cake set for at least 15 minutes before slicing and serving to allow the fudge to firm up slightly for clean service.Look for The frosting should appear glossy and hold its shape well when spread across the surface of the cooled cake.Tip For easier spreading, slightly warm the fudge icing in a double boiler if it feels too stiff to manage.
The cake must be completely cool to the touch before any icing is applied. The fudge frosting should be smooth, shiny, and thick enough to hold its shape when swirled across the surface. Once applied, allow the frosting to set for 15 minutes, which will help the icing firm up and create a professional, clean finish for easier serving and presentation.
Common mistakes
A common mistake is failing to rinse the sauerkraut well, which can add unwanted saltiness. Another error is neglecting to cool the cake fully before frosting; heat will cause the fudge icing to melt into a thin glaze rather than maintaining its creamy, spreadable consistency.
Additionally, ensure you do not over-mix the batter once the sauerkraut is added, as this can lead to a tougher, denser cake instead of the desired light and moist crumb structure.
How to tell it’s done
The cake is done when the top is set and feels springy to the touch. A toothpick or cake tester inserted into the center must come out clean. Once finished, remove the dish from the oven and allow it to cool on a wire rack for at least 30 minutes before proceeding to the frosting stage.
