How to Make Rhabarber Streuselkuchen Step by Step

1. Prepare the Cake Base: In a large bowl, mix flour, sugar, baking powder, and salt. Add the cold, cubed butter and egg. Use your fingers or a pastry blender to combine until it forms coarse crumbs.
2. Press the mixture into the bottom of a greased and floured springform pan (about 9 inches). Make sure the base is even.
3. Make the Rhubarb Filling: In a separate bowl, combine the chopped rhubarb, sugar, cornstarch, and vanilla extract. Mix well to coat the rhubarb evenly.
4. Pour the rhubarb mixture over the prepared cake base. Spread evenly across the base.
5. Prepare the Streusel Topping: In another bowl, combine flour, sugar, and cinnamon for the streusel. Add the cold, cubed butter. Use your fingers to rub the butter into the dry ingredients until it forms coarse crumbs.
6. Sprinkle the streusel topping evenly over the rhubarb filling. Make sure to cover the entire surface.
7. Bake the Cake: Preheat your oven to 180°C (350°F). Bake for 45-50 minutes, or until the streusel topping is golden brown and the rhubarb is tender.
8. Cool and Serve: Let the cake cool completely in the pan before removing it. This helps the cake to set properly. Serve slices of Rhabarber Streuselkuchen warm or at room temperature.

Expert Tips for Best Results

• Use cold butter for both the cake base and streusel. This ensures a flaky crust and crumbly topping.
• Don’t overmix the cake base. Overmixing can result in a tough crust.
• Adjust the amount of sugar in the rhubarb filling based on your preference. If your rhubarb is very tart, add more sugar.
• For extra flavor, add a pinch of ground ginger or cardamom to the streusel topping. This will enhance the warm spices.
• If the streusel topping starts to brown too quickly, cover the cake with foil. This prevents burning during baking.
• Let the cake cool completely before slicing to prevent it from falling apart. Patience is key!
• You can freeze Rhabarber Streuselkuchen for later enjoyment. Wrap it tightly in plastic wrap and foil.
• Consider adding other fruits like strawberries or apples to the rhubarb filling. This creates a more complex flavor profile.

How to Serve and Store

Serve Rhabarber Streuselkuchen warm or at room temperature. A dollop of whipped cream or a scoop of vanilla ice cream complements it perfectly. Dusting the cake with powdered sugar adds a nice touch.

Store leftover Rhabarber Streuselkuchen in an airtight container at room temperature for up to 3 days. You can also store it in the refrigerator for up to 5 days. Reheat gently in the oven or microwave before serving, if desired.

Frequently Asked Questions

Can I use frozen rhubarb?

Yes, you can use frozen rhubarb. Thaw it completely and drain any excess liquid before using it in the filling. Adjust the cornstarch slightly if the rhubarb is very watery.

Can I make this cake gluten-free?

Yes, you can substitute the all-purpose flour with a gluten-free flour blend. Ensure the blend contains xanthan gum for binding. The texture might be slightly different, but it will still be delicious.

How do I prevent the cake base from becoming soggy?

Blind baking the cake base for 10 minutes before adding the filling can help. This creates a barrier and prevents the rhubarb juices from soaking into the crust. Also, ensure you drain excess liquid from the rhubarb if using frozen.

Can I add nuts to the streusel topping?

Absolutely! Adding chopped nuts like almonds, walnuts, or pecans to the streusel topping adds a lovely crunch and flavor. About 50g of chopped nuts is a good amount.

Can I make this cake ahead of time?

Yes, you can make Rhabarber Streuselkuchen a day ahead. Store it in the refrigerator and bring it to room temperature before serving. The flavors will meld together beautifully overnight.
