Ingredient Spotlight
The star of Rabarberkage is undoubtedly the chopped fresh rhubarb. Its tartness is what gives the cake its signature flavor, perfectly balancing the sweetness of the sugar. Fresh rhubarb creates a delightful texture, adding a slight chewiness. If fresh rhubarb isn’t available, frozen rhubarb can be a good substitute; just thaw and drain any excess moisture before using.

Step-by-Step Instructions
Preparing Ingredients
Preheat your oven to 180°C (350°F). Grease a baking dish to prevent sticking.
In a mixing bowl, combine the chopped rhubarb with 1.5 tablespoons of sugar. Toss to coat and set aside. This will help draw out the moisture and sweetness from the rhubarb.
Mixing the Batter
In another bowl, whisk together the eggs and 200 grams of granulated sugar until the mixture is light and fluffy, about 3-4 minutes. The air incorporated will create a lovely texture.
Add the flour, baking powder, salt, vanilla extract, vegetable oil, and milk to the egg mixture. Mix until just combined and smooth, being careful not to overmix.
Pouring and Topping
Gently fold the rhubarb mixture into the batter, ensuring even distribution throughout.
Pour the batter into the prepared baking dish, smoothing the top with a spatula.
If desired, sprinkle a layer of Demarara sugar on top for a delightful crunch and added sweetness.
Baking the Cake
Bake the cake in the preheated oven for about 30 minutes, or until a toothpick inserted in the center comes out clean. You'll know it's ready when the top is golden brown and slightly springy to the touch.
Cooling and Serving
Once baked, remove the cake from the oven and let it cool in the baking dish for about 10 minutes.
Carefully transfer the cake to a wire rack to cool completely. This will help maintain its texture and prevent it from getting soggy.
Once cooled, cut into pieces and serve. Enjoy it plain, or add a dollop of whipped cream for an extra special treat!
Variations
- Add a teaspoon of cinnamon or nutmeg for a warm spice twist.
- Incorporate other fruits like strawberries or blueberries for a mixed fruit cake.
- For a gluten-free option, substitute all-purpose flour with a gluten-free baking blend.
- Experiment with different toppings like a cream cheese frosting or a simple glaze.
Serving and Storage Tips

Storage
Store any leftovers in an airtight container in the fridge for up to 3 days. For longer storage, freeze the cake for up to 2 months. Reheat gently in the oven or enjoy it cold straight from the fridge!
Common Mistakes
- Using cold eggs: Make sure your eggs are at room temperature for better mixing and fluffiness.
- Overmixing the batter: Mix just until combined to avoid a dense cake.
- Not measuring rhubarb correctly: Too much rhubarb can make the cake soggy; stick to the recommended amount.
- Skipping the cooling step: Allow the cake to cool completely to maintain its texture and flavor.
Helpful Notes
- If you're out of vanilla extract, almond extract works beautifully as a substitute.
- For a richer flavor, consider adding lemon zest to the batter.
- Chopped nuts like almonds or walnuts can be added for extra crunch.
- To make it dairy-free, replace milk with almond milk or any plant-based alternative.
