Instructions

1. Step 1: Preheat oven to 350°F and grease a 9-inch square baking pan. In a large bowl, whisk together 2 cups all-purpose flour, 3/4 cup granulated sugar, 2 tsp baking powder, and 1/2 tsp salt until well combined.
2. Step 2: In another bowl, whisk 2 large eggs, 1 cup whole milk, 1/2 cup melted unsalted butter, and 2 tsp vanilla extract until smooth. Pour the wet ingredients into the dry ingredients and gently fold until just combined.
3. Step 3: Carefully fold in 1 1/2 cups fresh blueberries, taking care not to break them.
4. Step 4: For the streusel topping, combine 1/2 cup brown sugar, 1 tsp ground cinnamon, 1/3 cup all-purpose flour, and 3 tbsp cold cubed unsalted butter in a small bowl. Use your fingers or a pastry cutter to blend until crumbly.
5. Step 5: Pour the batter into the prepared pan and evenly sprinkle the streusel over the top.
6. Step 6: Bake for 40-45 minutes until a toothpick inserted in the center comes out clean and the top is golden brown.
