- 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
Blueberry Lemon Brioche Cake: Crafting the Brioche Dough
Step 1: Activating the Yeast and Mixing the Dough
To begin extract crafting your Blueberry Lemon Brioche Cake, we first need to get our brioche dough started. In a small bowl, gently warm the whole milk. It should feel lukewarm to the touch, not hot – think bathwater temperature. This is crucial because if the milk is too hot, it will kill the yeast. Stir in 1 teaspoon of active dry yeast and 1 tablespoon of granulated sugar. Give it a gentle whisk, cover the bowl with a clean kitchen towel, and let it sit in a warm place for about 5 to 10 minutes. You’re looking for the mixture to become foamy and bubbly. This indicates that the yeast is alive and active and ready to work its magic. While the yeast is awakening, in a large mixing bowl, combine 160g (1 1/3 cups) of all-purpose flour and 3/4 teaspoon of salt. Make a well in the center of the dry ingredients. Once your yeast mixture is bubbly, pour it into the well. Add your room-temperature egg to the well as well. Using a wooden spoon or a sturdy spagin extracta, begin to mix everything together from the center outwards, gradually incorporating the flour. Continue mixing until a shaggy dough forms.
Step 2: Developing the Dough and Incorporating Butter
Now it’s time to knead the dough. Turn the shaggy dough out onto a lightly floured surface. Knead for about 5 to 7 minutes until the dough becomes smoother and more elastic. It will still be a bit sticky, which is normal for brioche. Now, we gradually incorporate the softened butter. Add the 56g (4 tablespoons) of room-temperature unsalted butter, a tablespoon at a time, working it into the dough. This step requires patience. Push, fold, and turn the dough repeatedly. As you add each piece of butter, the dough might seem to break down or become greasy, but keep kneading. The gluten structure will eventually absorb the fat, resulting in a wonderfully rich and pliable dough. Continue kneading for another 10 to 15 minutes, or until the dough is very smooth, elastic, and pulls away cleanly from your hands and the work surface. It should pass the windowpane test: if you can gently stretch a small piece of dough thinly enough to see light through it without tearing, it’s ready.
Step 3: First Proofing and Preparing the Blueberry Filling
Once your brioche dough is smooth and elastic, shape it into a ball. Lightly grease the mixing bowl with a little oil or butter. Place the dough ball in the bowl, turning it to coat lightly. Cover the bowl tightly with plastic wrap or a damp kitchen towel. Let the dough rise in a warm, draft-free place for 1 to 1.5 hours, or until it has doubled in size. While the dough is proofing, let’s prepare the vibrant blueberry filling. In a medium saucepan, combine the 380g (2 3/4 cups) of frozen wild blueberries, 75g (1/4 cup + 2 tablespoons) of granulated sugar, and the zest of 1 lemon. Cook over medium heat, stirring occasionally, until the blueberries start to break down and release their juices, about 5 to 7 minutes. In a small bowl, whisk together the 32g (1/4 cup) of cornstarch with the 42g (3 tablespoons) of lemon juice until smooth. This cornstarch slurry will help thicken our blueberry filling. Pour the cornstarch mixture into the simmering blueberries, stirring constantly. Continue to cook for another 1 to 2 minutes, until the filling thickens to a jam-like consistency. Remove the pan from the heat and let the blueberry filling cool completely. This is important; adding hot filling to the dough will melt the butter and can ruin the texture.
Crafting the Streusel Topping
Step 4: Assembling the Streusel and Preparing for Baking
Once the brioche dough has doubled and the blueberry filling has cooled, it’s time to assemble. Gently punch down the risen brioche dough to release the air. Turn it out onto a lightly floured surface. For the streusel topping, in a medium bowl, combine the 65g (1/3 cup) of light brown sugar and 90g (3/4 cup) of all-purpose flour. Add the 45g (3 1/4 tablespoons) of softened unsalted butter. Using your fingertips or a pastry blender, work the butter into the dry ingredients until the mixture resembles coarse crum extractbs. You want some small pea-sized pieces of butter to remain; this will give the streusel a lovely texture. Now, let’s assemble the cake. Lightly grease and flour a cake pan (an 8-inch or 9-inch round pan works well, or a loaf pan). You can also line it with parchment paper. Roll out the brioche dough into a circle or rectangle, roughly the size of your prepared pan, about 1/2 inch thick. Carefully transfer the dough to the prepared pan. Spoon the cooled blueberry filling evenly over the top of the brioche dough, leaving a small border around the edges. Sprinkle the prepared streusel topping generously over the blueberry filling.
Step 5: Second Proofing and Baking the Blueberry Lemon Brioche Cake
Now that your Blueberry Lemon Brioche Cake is assembled, it needs a final proof. Cover the pan loosely with plastic wrap or a kitchen towel and let it rest in a warm place for another 30 to 45 minutes, or until the dough has visibly puffed up again. Preheat your oven to 180°C (350°F). Once the cake has finished its second proof, it’s ready for the oven. Bake for 30 to 40 minutes, or until the streusel topping is golden brown and the brioche is cooked through. You can test for doneness by inserting a toothpick into the center; it should come out clean, or withrum extractist crumbs attached (but no wet batter). If the topping starts to brown too quickly before the cake is cooked, you can loosely tent it with aluminum foil. Once baked, remove the cake from the oven and let it cool in the pan on a wire rack for at least 20-30 minutes before attempting to remove it. This cooling period is important for the cake to set properly. For the best flavor and texture, let it cool almost completely before slicing and serving. Enjoy your delicious homemade Blueberry Lemon Brioche Cake!
