How to Make German Blueberry Streusel Cake
Step 1: Preheat the Oven
Preheat your oven to 180°C (350°F / Gas 4). Grease the sides of a 26cm (10 in.) springform cake pan and line the base with baking parchment paper.
Step 2: Make the Streusel
In the bowl of your stand mixer fitted with the dough hook attachment:
1. Combine 125 g unsalted butter, 125 g white sugar, and 125 g plain flour on low speed until the mixture resembles rough pebbles.
2. Transfer the mixture to a small bowl, cover with plastic wrap, and chill while preparing the cake batter.
Step 3: Make the Cake Batter
Using the paddle attachment:
1. Beat 125 g unsalted butter until light and fluffy.
2. Gradually add in 125 g white sugar, beating until well combined.
3. Add in two eggs one at a time, mixing thoroughly after each addition along with 2 tsp vanilla extract.
Step 4: Add Dry Ingredients
Sift together:
1. 250 g plain flour,
2. 15 g baking powder,
3. 2 tsp lemon zest,
4. A pinch of salt.
5. Mix on low speed until just combined.
Step 5: Assemble the Cake
- Spread the batter evenly over the base of your prepared pan using a spatula.
- Place the washed blueberries on top of the batter—don’t worry if it looks crowded as they will cook down.
- Sprinkle the chilled streusel over the blueberries as evenly as possible.
Step 6: Bake
Bake in the bottom third of your preheated oven for about 60 minutes or until golden brown and bubbling around the edges. If necessary, tent loosely with aluminum foil if browning too quickly.
Step 7: Cool
Allow cooling in the pan for about 30 minutes before transferring to a wire rack to cool completely. Once cooled, transfer to a serving plate and dust with powdered sugar before serving.

Serving German Blueberry Streusel Cake is all about enhancing its delightful flavors. This cake pairs beautifully with various accompaniments that complement its sweetness and texture. Here are some fantastic serving suggestions to elevate your experience.
With Whipped Cream
- Fresh whipped cream adds a light and airy texture that balances the cake’s richness. Simply whip heavy cream with a bit of sugar until soft peaks form.
Alongside Coffee or Tea
- A warm cup of coffee or tea enhances the cake’s flavors and makes for a cozy experience. Choose a light roast coffee or a citrus-infused tea for the best pairing.
Topped with Fresh Berries
- Garnishing with extra blueberries or mixed berries provides a fresh burst of flavor and a beautiful presentation. Just scatter them on top before serving.
With Vanilla Ice Cream
- A scoop of creamy vanilla ice cream melts into the warm cake, creating a delicious contrast in temperature and texture.
Drizzled with Lemon Glaze

How to Perfect German Blueberry Streusel Cake
To ensure your German Blueberry Streusel Cake turns out perfectly every time, consider these helpful tips.
- Use Fresh Blueberries: Fresh blueberries provide the best flavor and moisture. If using frozen, make sure they are thawed and drained well.
- Room Temperature Ingredients: Ensure your butter and eggs are at room temperature for better mixing and a fluffier texture.
- Don’t Overmix: When adding dry ingredients, mix just until combined to keep the cake tender. Overmixing can lead to a dense texture.
- Check Oven Temperature: Use an oven thermometer to confirm your oven is at the correct temperature, as inaccurate ovens can affect baking times.
- Cool Properly: Allowing the cake to cool in the pan helps it set properly before transferring it to a wire rack, preventing it from breaking apart.
- Store Correctly: Keep leftovers covered at room temperature for up to three days or refrigerate for longer freshness, but bring back to room temperature before enjoying.

Best Side Dishes for German Blueberry Streusel Cake
Pairing side dishes with your German Blueberry Streusel Cake can enhance your dessert experience. Here are some delicious options to consider:
- Greek Yogurt: Creamy Greek yogurt offers a tangy contrast that complements the sweetness of the cake while adding protein.
- Fruit Salad: A refreshing fruit salad brings additional flavors and textures that pair well with the blueberry notes in the cake.
- Cheese Platter: A selection of mild cheeses can balance sweetness with savory elements, making each bite interesting and unique.
- Nuts & Seeds: Roasted almonds or walnuts add crunchiness, providing an excellent contrast to the soft cake texture while enhancing nutrition.
- Coconut Cream: Lightly sweetened coconut cream creates a tropical twist that pairs wonderfully with blueberries, adding richness without overpowering flavors.
- Toasted Oats: Sprinkling some toasted oats on top brings extra crunch and nutty flavor that harmonizes beautifully with this dessert.
Common Mistakes to Avoid
When baking German Blueberry Streusel Cake, it’s easy to make a few common errors. Here are some mistakes to watch out for.
- Incorrect oven temperature – Always preheat your oven to the right temperature before baking. A too-hot oven can burn the cake, while a cooler one will leave it undercooked.
- Overmixing the batter – Mixing too much can lead to a dense cake instead of a light and fluffy texture. Mix until just combined for the best results.
- Skipping the chilling step for streusel – Chilling the streusel before adding it to the cake helps create that delightful crumbly topping. Don’t rush this step!
- Not using fresh blueberries – Fresh blueberries provide the best flavor and texture. Frozen ones can make the cake soggy, so choose wisely.
- Neglecting to check doneness visually – You may not be able to test with a toothpick due to all the fruit. Instead, look for a golden brown color and bubbling berries on top.
Refrigerator Storage
- Store in an airtight container.
- Keep in the fridge for up to 4 days.
Freezing German Blueberry Streusel Cake
- Wrap slices tightly in plastic wrap or foil.
- Freeze for up to 2 months for best quality.
Reheating German Blueberry Streusel Cake
- Oven – Preheat your oven to 180°C (350°F) and warm the cake for about 10-15 minutes until heated through.
- Microwave – Heat individual slices on medium power for 30-60 seconds. Keep an eye on it to avoid overheating.
