Ingredients

This German Blueberry Cake recipe is thoughtfully divided into three key components, each contributing to the final masterpiece: the shortcrust pastry base, the luscious blueberry filling, and the irresistible streusel topping. Here’s a detailed breakdown of what you’ll need:

Ingredients for Shortcrust Pastry

The foundation of our Blueberry Kuchen is a tender and slightly crumbly shortcrust pastry. These ingredients work together to create the perfect base that’s neither too sweet nor overpowering, allowing the blueberry filling to truly shine.

• All-Purpose Flour: 200 g (7 oz) or 1 2/3 cups. The backbone of our pastry, all-purpose flour provides structure. Sifting it ensures a lighter, less dense dough.
• Baking Powder: 1 ½ teaspoons. This leavening agent gives the pastry a slight lift, preventing it from becoming too dense and ensuring a tender crumb.
• Sugar: 75 g (2.6 oz) or 6 tablespoons. Just enough sweetness to complement the blueberries without making the pastry itself overly sugary.
• Vanilla Extract: 1 teaspoon. A touch of vanilla enhances the overall flavor profile of the pastry, adding warmth and depth.
• Egg (XL): 1 large egg, extra-large if possible. The egg adds richness, moisture, and helps bind the dough together. Using an extra-large egg ensures the right balance of moisture in the pastry.
• Soft Cold Butter: 100 g (3.5 oz) or 7 tablespoons. Cold butter is crucial for creating a flaky shortcrust pastry. It should be soft enough to incorporate but still cool to the touch.
• Pinch of Salt: A small pinch of salt enhances the flavors of all the other ingredients and balances the sweetness.

Ingredients for Filling

The heart of this Kuchen is the vibrant and flavorful blueberry filling. This homemade filling is far superior to store-bought options, offering a fresh, intensely blueberry flavor that is both sweet and tart.

• Blueberries: 1 kg (2.2 lb) or 4 cups. Fresh blueberries are ideal for this recipe, offering the best flavor and texture. However, frozen blueberries can be used if thawed and drained thoroughly.
• Sugar: 100 g (1/2 cup). Sugar sweetens the blueberries and helps to draw out their juices, creating a luscious sauce as they cook.
• Lemon Juice: 2 tablespoons. Lemon juice brightens the blueberry flavor, adding a touch of acidity that balances the sweetness and prevents the filling from becoming cloying.
• Lemon Zest: 1 teaspoon. Lemon zest adds a fragrant, citrusy note that complements the blueberries beautifully, enhancing their natural flavor.
• Pudding Powder (Vanilla) OR Cornstarch: 50 g (1.76 oz) or 1/3 cup vanilla pudding powder OR 50g (1/3 cup) cornstarch + 1 tablespoon vanilla extract. This acts as a thickener for the blueberry filling. Vanilla pudding powder adds a subtle vanilla flavor and creamy texture, while cornstarch (with added vanilla extract) provides a neutral thickening power, allowing the blueberry flavor to remain dominant.

Ingredients for Streusel Topping

No German Kuchen is complete without a generous streusel topping. This crumbly, buttery mixture adds a delightful textural contrast to the soft pastry and juicy filling, as well as a touch of buttery sweetness.

• All-Purpose Flour: 100 g (3.5 oz) or 3/4 cups. Provides structure to the streusel, creating those perfect crumbs.
• Sugar: 75 g (2.6 oz) or 6 tablespoons. Sweetens the streusel and helps it to caramelize beautifully in the oven.
• Vanilla Extract: 1 teaspoon. Adds a warm, aromatic note to the streusel, complementing the other flavors.
• Soft Cold Butter: 80 g (2.6 oz) or 6 tablespoons. Cold butter is essential for achieving that crumbly streusel texture. It should be soft enough to work with but still cool.

Instructions

Embark on a delightful baking journey with these step-by-step instructions to create your own authentic German Blueberry Kuchen. Each stage is carefully outlined to guide you from preparing the luscious blueberry filling to achieving the perfect golden-brown streusel topping.

Preparation of the Blueberry Filling

This initial step is crucial for developing the rich and flavorful heart of your Kuchen. Gently cooking the blueberries with sugar and lemon brings out their natural sweetness and creates a beautifully thickened sauce.

1. Wash the Blueberries: Begin by gently washing the blueberries in a colander under cool running water. Ensure you remove any stems or bruised berries.
2. Combine Ingredients in a Saucepan: Place the washed blueberries in a medium-sized saucepan. Add the sugar, lemon juice, and lemon zest to the saucepan.
3. Bring to a Gentle Boil: Set the saucepan over low to medium heat. Stir continuously with a spoon, working from the sides towards the center of the pan. This gentle stirring prevents the blueberries from sticking to the bottom and burning.
4. Simmer Briefly: Once the mixture reaches a gentle boil, let it simmer for approximately 3 minutes, no longer. The goal is to soften the blueberries and release their juices, but we want to keep them mostly whole for texture.
5. Prepare the Thickening Agent: In a small bowl, dissolve the vanilla pudding powder (or cornstarch and vanilla extract) with 5 tablespoons of cold water. Stir until you have a smooth, lump-free mixture.
6. Thicken the Filling: Pour the pudding powder (or cornstarch) mixture into the simmering blueberries. Continue to stir with your spoon until the color of the blueberry mixture deepens and becomes slightly reddish.
7. Bubble and Remove from Heat: Let the blueberry filling bubble up once, which indicates that the thickening agent has activated. Immediately remove the saucepan from the heat.
8. Cool the Filling: Pour the hot blueberry mixture into a separate bowl. Allow it to cool slightly before pouring it into your prepared baking pan. This prevents the hot filling from melting the pastry dough. Ensure the filling is poured evenly over the pastry, reaching all the way to the edges.

Preparation of the Shortcrust Pastry

Crafting the perfect shortcrust pastry is key to a delicious Kuchen. This method ensures a tender, slightly crumbly base that complements the moist filling and crunchy streusel.

1. Sift Dry Ingredients: Using a flour sifter, sift the all-purpose flour and baking powder together into a large mixing bowl. Sifting aerates the flour and baking powder, resulting in a lighter pastry.
2. Add Sugar and Salt: Add the sugar and salt to the sifted flour mixture. Whisk everything together thoroughly to ensure the dry ingredients are evenly combined.
3. Create a Well and Add Wet Ingredients: Make a well in the center of the dry ingredients. Crack the egg into the well. Cut the cold butter into small cubes and distribute them evenly over the flour mixture.
4. Knead the Dough: Using your hands or a hand mixer fitted with dough hooks, begin to knead the ingredients together. Work the dough until it comes together into a smooth ball. The dough is ready when it is no longer sticky to the touch. Be careful not to over-knead, as this can result in a tough pastry.
5. Prepare the Springform Pan: Line the base of a 9-inch springform pan with parchment paper. This makes it easier to remove the cake after baking.
6. Shape the Pastry Base: Take slightly more than half of the pastry dough and press it evenly onto the bottom of the prepared springform pan. Use your fingers to press the dough up the sides of the pan, creating a slight edge.
7. Form the Outer Crust: Divide the remaining pastry dough in half. Roll each half into a long roll. Place these rolls around the inside edge of the springform pan, on top of the pastry base.
8. Seal and Shape the Crust: Use your fingers to press the pastry rolls against the sides of the springform pan, creating a raised edge that is approximately 2 inches high. Seal the edge firmly to the bottom pastry, ensuring there are no gaps.
9. Prick the Base: Use a fork to prick small holes across the base of the pastry. This prevents the pastry from puffing up unevenly during baking.
10. Pour in the Filling: Carefully pour the cooled blueberry filling evenly over the prepared pastry base.

Preparation of the Streusel Topping

The streusel topping is the crowning glory of this Kuchen, adding a delightful crunch and buttery sweetness. It’s quick and easy to prepare, enhancing both the texture and flavor of the cake.

1. Combine Streusel Ingredients: In a separate mixing bowl, combine the all-purpose flour, sugar, and vanilla extract for the streusel topping.
2. Incorporate the Butter: Add the cold butter to the bowl. Using your fingertips or the dough hooks of your handheld mixer, work the butter into the dry ingredients.
3. Create Crumbs: Continue to work the mixture until it forms coarse crumbs. A helpful technique is to rub the dough between your hands, allowing the crumbles to fall back into the bowl. Ensure the butter is evenly distributed throughout the crumbs.
4. Adjust Consistency (if needed): Check the consistency of the streusel. If it appears too dry, add a little more butter, a tablespoon at a time. If it seems too moist, add a bit more flour, a tablespoon at a time, until you achieve the desired crumbly texture.
5. Distribute Streusel Evenly: Sprinkle the streusel topping evenly over the blueberry filling in the springform pan. Ensure it covers the entire surface for a consistent crumble layer.

Baking the German Blueberry Kuchen

The final baking step transforms all your preparations into a golden, fragrant, and utterly delicious German Blueberry Kuchen.

1. Preheat the Oven: Preheat your oven to 182°C (360°F). Make sure the oven rack is positioned in the middle.
2. Bake the Kuchen: Place the springform pan with the assembled Kuchen on the middle rack of the preheated oven.
3. Baking Time: Bake for approximately 40-45 minutes, or until the streusel topping is golden brown and the pastry is cooked through.
4. Enhance Streusel Color (Optional): For a deeper golden color on the streusel, you can move the cake to a rack higher in the oven for the last 5 minutes of baking. Watch carefully to prevent burning.
5. Cool in the Pan: Once baked, remove the Kuchen from the oven and let it cool completely in the springform pan. This allows the filling to set and the cake to become easier to handle.
6. Remove from Springform Pan: After the cake has cooled completely, carefully release it from the springform pan. Gently slide a cake lifter or large spatula underneath to transfer it to a serving plate.
7. Garnish and Serve: Sprinkle the top of the cooled Blueberry Kuchen with powdered sugar for an elegant finish. Serve slices of this delightful cake, ideally with a dollop of freshly whipped cream.

Additional Tips for Baking the Perfect German Blueberry Kuchen

To ensure your German Blueberry Kuchen is a resounding success, consider these helpful tips gleaned from baking experience and Kuchen enthusiasts:

1. Use Cold Butter (and Keep it Cold): Cold butter is crucial for both the shortcrust pastry and the streusel topping. It prevents the gluten in the flour from developing too much, resulting in a tender pastry and crumbly streusel. Work quickly with the butter and if your kitchen is warm, consider chilling the dough briefly before rolling or crumbling.
2. Don’t Overmix the Pastry Dough: Overmixing develops the gluten in the flour, leading to a tough pastry. Mix just until the dough comes together and is no longer sticky. A slightly shaggy dough is perfectly fine.
3. Taste and Adjust the Filling: Before pouring the blueberry filling into the pastry, taste it. Adjust the sweetness or tartness to your preference by adding a little more sugar or lemon juice. The flavor of the filling will intensify as it bakes.
4. Evenly Distribute the Streusel: Ensure the streusel topping is evenly distributed over the blueberry filling. This will ensure a consistent crumbly texture and golden-brown color across the entire surface of the Kuchen. If you have larger clumps of streusel, break them up before sprinkling.
5. Monitor Baking Time and Adjust Rack Position: Ovens can vary in temperature. Keep an eye on your Kuchen during baking. If the streusel is browning too quickly but the pastry doesn’t seem fully baked, you can loosely tent the cake with foil for the remaining baking time. As mentioned in the instructions, moving the cake to a higher rack for the last few minutes can enhance the golden color of the streusel.

FAQ Section – German Blueberry Kuchen

Baking a German Blueberry Kuchen can bring up a few questions, especially if you are new to this type of dessert. Here are answers to some frequently asked questions to help you bake with confidence:

Q1: Can I use frozen blueberries instead of fresh blueberries?

A: Yes, you can use frozen blueberries. However, it’s important to thaw them completely and drain off any excess liquid before using them in the filling. Frozen blueberries tend to release more moisture than fresh ones, so draining them well will prevent your filling from becoming too watery. You may also need to cook the filling slightly longer to reduce excess liquid.

Q2: Can I make the pastry dough or streusel topping ahead of time?

A: Absolutely! Both the shortcrust pastry dough and the streusel topping can be made ahead of time. For the pastry dough, wrap it tightly in plastic wrap and store it in the refrigerator for up to 2 days. For the streusel topping, store it in an airtight container in the refrigerator for up to 3 days. When ready to bake, let the pastry dough soften slightly at room temperature for easier rolling and crumbling.

Q3: Can I substitute the vanilla pudding powder in the filling?

A: Yes, if you don’t have vanilla pudding powder, you can easily substitute it with cornstarch. Use the same amount of cornstarch (50g or 1/3 cup) and add 1 tablespoon of vanilla extract to the blueberry filling along with the cornstarch mixture. This will provide the thickening power needed for the filling and maintain a delicious vanilla flavor.

Q4: How do I store leftover German Blueberry Kuchen?

A: Leftover German Blueberry Kuchen should be stored in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 4 days. If storing at room temperature, ensure it’s in a cool, dry place. Refrigeration will extend its shelf life, especially in warmer climates, but the pastry might become slightly less crumbly. You can gently warm individual slices in the microwave or oven to restore some of the pastry’s texture.

Q5: Can I make this Kuchen gluten-free?

A: Yes, you can adapt this recipe to be gluten-free. To make a gluten-free version, substitute the all-purpose flour in both the shortcrust pastry and the streusel topping with a good quality gluten-free all-purpose flour blend. Ensure the blend is designed for baking and contains xanthan gum or another binder to provide structure. Follow the recipe as instructed, keeping in mind that gluten-free pastry dough may be a bit more delicate to handle, so be gentle when pressing it into the springform pan. The baking time should remain similar, but always check for doneness using visual cues and a toothpick test for the pastry if needed.
