Ingredients:
- 80g (1/3 cup) whole milk
- 1 teaspoon active dry yeast
- 1 tablespoon granulated sugar
- 160g (1 1/3 cups) all-purpose flour
- 3/4 teaspoon salt
- 1 egg, room temperature
- 56g (4 tablespoons) unsalted butter, room temperature
- 380g (2 3/4 cups) frozen wild blueberries
- 75g (1/4 cup + 2 tablespoons) granulated sugar
- Zest of 1 lemon
- 32g (1/4 cup) cornstarch
- 42g (3 tablespoons) lemon juice
- 45g (3 1/4 tablespoons) unsalted butter
- 65g (1/3 cup) light brown sugar
- 90g (3/4 cup) all-purpose flour
Brioche Dough Preparation
Activating the Yeast
In a small bowl, combine the whole milk, 1 teaspoon of active dry yeast, and 1 tablespoon of granulated sugar. Whisk gently to ensure the sugar and yeast are mostly dissolved. Let this mixture sit in a warm spot for about 5-10 minutes. You’ll know the yeast is active when it becomes foamy and bubbly on the surface, indicating it’s ready to work its magic in the dough. If you don’t see any activity, your yeast might be expired, and you’ll need to start with a fresh packet.
Mixing the Dough
In the bowl of a stand mixer fitted with a dough hook, add 160g of all-purpose flour and 3/4 teaspoon of salt. Give it a quick mix to distribute the salt evenly. Pour in the activated yeast mixture and the room-temperature egg. Start mixing on low speed until a shaggy dough begin extracts to form. Allow the mixer to run for about 5 minutes, gradually increasing the speed to medium-low. The dough should start to pull away from the sides of the bowl.
Incorporating the Butter
Once the dough has developed some structure, it’s time to add the butter. Cut the 56g of room-temperature unsalted butter into small cubes. With the mixer still running on low speed, add the butter cubes one by one, allowing each piece to be mostly incorporated before adding the next. This process might take a few minutes, but it’s crucial for achieving a rich, tender brioche. After all the butter is added, increase the mixer speed to medium and continue to knead for another 8-10 minutes. The dough should become smooth, elastic, and slightly sticky. It should pass the windowpane test: when you gently stretch a small piece of dough, it should become thin enough to see light through without tearing.
First Rise
Lightly grease a clean bowl with a little oil or butter. Place the brioche dough into the greased bowl and turn it to coat. Cover the bowl tightly with plastic wrap or a damp kitchen towel. Let the dough rise in a warm place for 1 to 1.5 hours, or until it has doubled in size. The exact time will depend on the ambient temperature of your kitchen.
Blueberry Filling Preparation
Creating the Blueberry Mixture
While the brioche dough is rising, let’s prepare the delicious blueberry filling. In a medium saucepan, combine the 380g of frozen wild blueberries, 75g of granulated sugar, and the zest of 1 lemon. Stir gently to coat the blueberries.
Thickening the Filling
In a small bowl, whisk together the cornstarch and lemon juice until it forms a smooth slurry. Pour this slurry into the saucepan with the blueberries and sugar. Place the saucepan over medium heat. Stir continuously as the mixture heats up. You’ll notice the blueberriesgin extractll begin to break down and release their juices, and the mixture will start to thicken. Cook for about 5-7 minutes, or until the filling has reached a jam-like consistency. Remove from the heat and let it cool completely. This cooling step is important; adding hot filling to the brioche dough will cause it to melt the butter and negatively impact the dough’s structure.
Assembling and Baking the Blueberry Lemon Brioche Cake
Shaping the Dough
Once the brioche dough has doubled in size, gently punch it down to deflate it. Turn the dough out onto a lightly floured surface. You can use a round 8 or 9-inch cake pan for this recipe. Butter the inside of the pan generously, or line it with parchment paper. Roll the brioche dough into a rough circle, about 1/4 inch thick. Spread the cooled blueberry filling evenly over the surface of the dough, leaving a small border around the edges.
Creating the Topping
Now for the delightful streusel topping. In a medium bowl, combine the 65g of light brown sugar, 90g of all-purpose flour, and the 45g of unsalted butter. Use your fingertips or a pastry blender to work the ingredients together until the mixture resembles coarse crum extractbs. This irum extractour crumb topping! Sprinkle this topping evenly over the blueberry filling.
Second Rise and Baking
Carefully transfer the assembled cake into the prepared cake pan. Cover the pan loosely with plastic wrap. Let the cake rise in a warm place for another 30-45 minutes, or until it looks visibly puffed up. Preheat your oven to 180°C (350°F). Bake the Blueberry Lemon Brioche Cake for 30-40 minutes, or until the brioche is golden brown and the topping is crisp and golden. You can test for doneness by inserting a toothpick into the center of the cake; it should come out clean. If the topping starts to brown too quickly, you can loosely tent the cake with aluminum foil.
Cooling and Serving
Once baked, remove the cake from the oven and let it cool in the pan for about 10-15 minutes. Then, carefully invert it onto a wire rack to cool completely. This Blueberry Lemon Brioche Cake is absolutely divine served warm or at room temperature. It makes for a wonderful breakfast treat, a delightful afternoon snack, or even a light dessert.

Frequently Asked Questions:
Q: Can I make the Blueberry Lemon Brioche Cake ahead of time?
A: Absolutely! The Blueberry Lemon Brioche Cake can be baked a day in advance and stored at room temperature, well-wrapped in plastic wrap and then in an airtight container. It might even be slightly more flavorful the next day as the flavors meld.
Q: My brioche dough is very sticky. Is this normal?
A: Yes, brioche dough is typically a very sticky and wet dough due to the high butter content. Don’t be tempted to add too much extra flour, as this will result in a tougher cake. It’s best to use a stand mixer with a dough hook and allow it to knead thoroughly. Chilling the dough also makes it much easier to handle.
Q: What kind of blueberries work best in this cake?
A: Fresh blueberries are ideal for the best texture and flavor. If using frozen blueberries, ensure they are completely thawed and patted dry before folding them into the batter to prevent the cake from becoming too wet.
