Ingredients

For the crumb topping: • 1 1/2 cups packed dark brown sugar • 2/3 cup granulated sugar • 1 tablespoon ground cinnamon • 1 teaspoon kosher salt • 2 sticks unsalted butter, melted • 3 cups all-purpose flour For the cake: • 3 cups all-purpose flour • 1 3/4 teaspoons baking powder • 3/4 teaspoon baking soda • 1 teaspoon kosher salt • 1 1/2 sticks unsalted butter, at room temperature • 1 3/4 cups granulated sugar • 3 large eggs • 1 tablespoon pure vanilla extract • 1 1/4 cups sour cream

Directions

Step 1

Combine the brown sugar, 2/3 cup granulated sugar, cinnamon, and 1 teaspoon kosher salt in a medium bowl.

Step 2

Add in 2 sticks of melted butter, mixing with a fork until just combined.

Step 3

Add 3 cups flour and mix with a fork until evenly distributed and small to medium clumps have formed. Be careful not to overmix.

Preheat the oven to 350 degrees F.

Step 5

Spray an 18x13-inch rimmed baking sheet with cooking spray.

Whisk together the remaining 3 cups flour with the baking powder, baking soda, and the remaining 1 teaspoon kosher salt in a medium bowl.

Beat the room temperature butter and the remaining 1 3/4 cups granulated sugar together in a large bowl with an electric mixer on medium-high speed until light and fluffy, about 5 minutes.

Step 9

Beat the vanilla into the butter mixture.

Reduce the mixing speed to low.

Spoon the cake batter into the prepared baking sheet, smoothing it with a plastic spatula.

Step 13

Sprinkle the crumb topping on top, pressing it gently into the batter to adhere it.

Bake until the cake and the topping are golden brown and a toothpick inserted into the center comes out clean, about 40-45 minutes.

Step 15

Let the cake cool in the pan completely for about 1 hour and then serve!
