Ingredients

• 2.5 cups all-purpose flour
• 1 cup granulated sugar
• 0.5 cup brown sugar
• 0.5 cup unsalted butter, melted and slightly cooled
• 2 teaspoons baking powder
• 0.5 teaspoon baking soda
• 0.25 teaspoon salt
• 2 pieces large eggs
• 1 teaspoon vanilla extract
• 0.75 cup buttermilk
• 2 cups blueberries, fresh or frozen
• 2 tablespoons powdered sugar (optional for dusting)

Directions

Step 1

Preheat your oven to 350°F (175°C) and grease a 9-inch square baking pan or line it with parchment paper.

Step 2

In a medium bowl, whisk together 1.5 cups of flour, granulated sugar, baking powder, baking soda, and salt.

Step 3

In a separate large bowl, whisk together the eggs, buttermilk, vanilla extract, and melted butter until smooth.

Step 4

Gradually add the dry ingredients into the wet ingredients, mixing until just combined. Do not overmix.

Step 5

Gently fold in the blueberries. Spread the batter evenly into the prepared baking pan.

Step 6

In another small bowl, prepare the crumb topping by combining the remaining 1 cup of flour, brown sugar, and an additional 0.5 cup of melted butter. Use your fingers to mix until the mixture resembles coarse crumbs.

Step 7

Sprinkle the crumb mixture evenly over the cake batter.

Step 8

Bake the cake in the preheated oven for 40-45 minutes, or until a toothpick inserted into the center comes out clean.

Step 9

Let the cake cool completely in the pan before slicing. Dust the top with powdered sugar, if desired, before serving.
