Directions

Step 1

In a large mixing bowl, whisk together 2 cups of all-purpose flour, 1 cup of granulated sugar, 2 teaspoons of baking powder, and 0.5 teaspoons of salt.

Step 2

In another bowl, combine 0.5 cups of melted unsalted butter, 0.75 cups of milk, 0.5 cups of sour cream, 2 large eggs, and 2 teaspoons of vanilla extract. Whisk until smooth.

Step 3

Gradually pour the wet ingredients into the dry ingredients and mix until just combined. Do not overmix.

Step 4

Gently fold in the 1.5 cups of fresh blueberries using a spatula.

Step 5

Grease a 9x13-inch baking dish and pour the batter into it, spreading it out evenly.

Step 6

In a small mixing bowl, prepare the streusel by combining 0.75 cups of brown sugar, 1.5 teaspoons of ground cinnamon, and 0.5 cups of all-purpose flour.

Step 7

Cut in 0.25 cups of cold, cubed unsalted butter using a fork or pastry cutter until the mixture resembles coarse crumbs.

Step 8

Sprinkle the streusel evenly over the top of the cake batter.

Step 9

Cover the baking dish with plastic wrap and refrigerate overnight.

Step 10

The next morning, preheat your oven to 350°F (175°C). Remove the plastic wrap from the baking dish.

Allow the cake to cool for 10 minutes before slicing and serving.
