This scrumptious Sour Cream Coffee Cake has a ribbon of cinnamon streusel in the middle and even more of the cinnamon-sugar goodness on top! It's perfect for breakfast and brunch, or even as a simple dessert with a scoop of vanilla ice cream!
Preheat the oven to 350°F. Spray a 9x13-inch pan with baking spray.
In a large bowl, whisk together the flour, brown sugar, granulated sugar, salt, and cinnamon for the streusel. Add the melted butter and stir until it clumps together like sand.
2 1/2 cups all-purpose flour, 1 1/4 cups brown sugar, 1/2 cup granulated sugar, 1/2 teaspoon salt, 1 1/2 Tablespoons ground cinnamon, 1 cup salted butter
In a separate large bowl, beat the butter and sugar on medium-high speed until creamy and light, about 2-3 minutes.
3/4 cup salted butter, 1 1/4 cups granulated sugar
Add the eggs, one at a time, beating after each addition. Scrape down the side of the bowl and mix in the sour cream and vanilla extract.
1 cup sour cream, 4 large large eggs, 2 teaspoons vanilla extract
Add the flour, baking powder, baking soda, and salt, mixing just until combined. The batter will be thick.
Spread 1/2 of the cake batter into the prepared pan. Sprinkle with half of the streusel, then dollop the remaining cake batter over this, using a knife to nudge the batter together to form a top layer as much as possible. Sprinkle the remaining streusel over the top layer of batter.
Bake for 50-55 minutes until golden brown on top and a toothpick inserted into the center of the cake comes out clean with just a few crumbs. Serve warm.

Notes
Optional: If you like a little nutty crunch in your coffee cake, try adding 1 1/2 cups chopped pecans to the streusel.
