To Make The Sour Cream Coffee Cake:
Preheat oven to 350℉. Lightly coat a 9×13-inch baking dish with nonstick baking spray.
In a large bowl, combine flour, baking soda, cinnamon, and salt.
In the bowl of an electric mixer fitted with the paddle attachment, beat butter and sugar on medium-high speed for about 2 to 3 minutes, until light and fluffy. Add in eggs, one at a time. Add in vanilla until well combined.
Mix in sour cream on low speed. Add dry ingredients in 3 parts while mixing.
Spread batter evenly over prepared baking dish. Sprinkle on the crumb topping. Use your fingertips to gently press the crumbs into the batter.
Bake for 45 to 50 minutes, or until a toothpick inserted in the center comes out clean. If crumb topping begins to get too dark while baking, loosely cover with aluminum foil.
Transfer the baking pan to a wire rack and cool completely (approximately 1 hour) before slicing and serving.
