Ingredients
Scale
- 2 cups (250g) all-purpose flour
- 1 cup (200g) granulated sugar
- 2 teaspoons baking powder
- 1 cup (240ml) whole milk
- 1/4 cup (57g) unsalted butter, melted
- 3 cups (450g) fresh blueberries
- 1 tablespoon lemon juice
- 1/2 cup (60g) all-purpose flour (for streusel)
- 1/3 cup (65g) granulated sugar (for streusel)
- 1 teaspoon ground cinnamon
- 3 tablespoons (42g) unsalted butter, cold and cubed (for streusel)
Instructions
- Preheat oven to 350°F (175°C). Line a 9×9 inch baking pan with parchment paper and grease lightly.
- In a medium bowl, whisk together 2 cups flour, 1 cup sugar, and baking powder.
- In a separate small bowl, whisk milk and melted butter together.
- Pour wet ingredients into dry ingredients and stir gently until just combined. Do not overmix.
- In a small bowl, toss blueberries with lemon juice (and optionally 1 tsp flour to prevent sinking).
- In another small bowl, combine 1/2 cup flour, 1/3 cup sugar, and cinnamon. Rub in cold cubed butter until mixture resembles coarse crumbs.
- Pour batter into prepared pan and spread evenly. Drop blueberries over the batter without stirring.
- Sprinkle cinnamon streusel generously over the top.
- Bake for 35-40 minutes until golden brown and a toothpick inserted into the cake comes out clean.
- Cool in the pan for 15-20 minutes before slicing and serving.
Notes
Keep butter cold for the streusel to ensure a crunchy texture. Do not overmix the batter to keep the cake tender. Fresh blueberries are recommended over frozen to prevent sogginess. If using frozen berries, do not thaw them first. The cake is meant to ‘buckle’ or sink slightly as it bakes.
