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
For the Brioche Dough:
1. Activating the Yeast and Mixing the Dough
In a small bowl, combine the 80g of whole milk, 1 teaspoon of active dry yeast, and 1 tablespoon of granulated sugar. Gently stir to combine, then let it sit for about 5-10 minutes. You’ll know the yeast is active when it becomes foamy and bubbly on the surface – this is a good sign that it’s ready to work its magic. While the yeast is blooming, in a large mixing bowl, whisk together the 160g of all-purpose flour and 3/4 teaspoon of salt. Make a well in the center of the dry ingredients. Once the yeast mixture is foamy, pour it into the well. Add the room-temperature egg to the well as well. Using a wooden spoon or a dough hook attachment on your stand mixer, begin to mix the ingredients until they just start to come together into a shaggy dough.
2. Developing the Brioche Dough
Now comes the enrichment that makes brioche so special. With the mixer on low speed (or by hand, kneading on a lightly floured surface), gradually add the 56g of room-temperature unsalted butter, a tablespoon at a time. Be patient with this step; it might seem like the dough is falling apart initially, but keep mixing. The butter needs time to be fully incorporated. Continue to mix or knead for about 8-10 minutes. The dough should become smooth, elastic, and slightly sticky. It will pull away from the sides of the bowl. Once the dough has developed sufficiently, place it in a lightly greased bowl, cover it tightly with plastic wrap, and let it rise in a warm place for about 1 to 1.5 hours, or until it has doubled in size. This initial rise is crucial for developing flavor and texture.
For the Blueberry Lemon Filling:
3. Preparing the Blueberry Lemon Mixture
While the brioche dough is rising, let’s prepare our luscious filling. In a medium saucepan, combine the 380g of frozen wild blueberries, 75g of granulated sugar, and the zest of one lemon. Stir to combine. In a small separate bowl, whisk together the 32g of cornstarch and the 42g of lemon juice until the cornstarch is fully dissolved and there are no lumps. This is our thickening agent. Pour the cornstarch slurry into the blueberry mixture in the saucepan.
4. Cooking the Blueberry Lemon Filling
Place the saucepan over medium heat. Stir the mixture constantly as it heats up. You’ll notice the blueberries will start to break down and release their juices. Continue to cook, stirring, until the mixture thickens considerably, coating the back of a spoon. This usually takes about 5-8 minutes. Once thickened, remove the saucepan from the heat and stir in the 45g of unsalted butter until it is completely melted and incorporated. This butter adds a lovely richness and sheen to the filling. Let the filling cool completely to room temperature. It’s important for the filling to be cool before layering it into the brioche.
Assembling and Baking the Blueberry Lemon Brioche Cake:
5. Shaping and Assembling the Cake
Once the brioche dough has doubled in size, gently punch it down to release the air. Turn the dough out onto a lightly floured surface. Roll or pat the dough into a rough rectangle, about 10×12 inches. Spread the cooled blueberry lemon filling evenly over the surface of the dough, leaving a small border around the edges. In a separate small bowl, combine the 65g of light brown sugar and 90g of all-purpose flour. Add the remaining 45g of room-temperature unsalted butter (cut into small pieces). Using your fingertips or a pastry blender, work the butter into the dry ingredients until the mixture resembles coarse crumbs. This is our streusel topping, which will add a delightful crunch to the cake. Sprinkle this streusel evenly over the blueberry filling.
6. Final Rise and Baking
Carefully roll up the dough from one of the longer sides, like a jelly roll, ensuring the filling stays enclosed. Pinch the seam to seal it. Gently shape the roll into a round wreath or an oval shape, tucking the ends underneath. Place the shaped dough onto a baking sheet lined with parchment paper. Cover loosely with plastic wrap and let it rise again for about 30-45 minutes, or until it looks puffy. Preheat your oven to 350°F (175°C). Bake the Blueberry Lemon Brioche Cake for 30-40 minutes, or until it is golden brown and sounds hollow when tapped on the bottom. If the top starts to brown too quickly, you can loosely tent it with aluminum foil. Let the cake cool on a wire rack for at least 15-20 minutes before slicing and serving. This allows the interior to set properly.

Frequently Asked Questions:
Q1: Can I use frozen blueberries instead of fresh?
Absolutely! If using frozen blueberries, I recommend tossing them with a tablespoon of flour before adding them to the batter to help prevent them from sinking. You might also need to bake the cake for a few extra minutes as frozen berries release more moisture.
Q2: How should I store this Blueberry Lemon Brioche Cake?
Once completely cooled, store the cake at room temperature in an airtight container for up to 3 days. If you live in a very warm climate, or if your kitchen is particularly humid, you may wish to store it in the refrigerator, though this can slightly alter the texture.
Q3: What makes this cake “brioche”?
The “brioche” aspect comes from the enriched dough, which includes a higher proportion of butter and eggs than a standard cake batter. This gives the cake its characteristic tender, slightly chewy, and incredibly rich crumb.
