Buttermilk Coffee Cake with Crumb Streusel is an easy cake recipe that will quickly become a favorite! Add a sprinkling cinnamon, pumpkin pie spice, or nuts to fit whatever flavor you're in the mood for.
Preheat the oven to 350 degrees. Spray a 9x13 baking pan with cooking spray.
Mix together the flour, salt, cinnamon, sugars and vegetable oil. Mix until crumbly. Scoop out 1 1/2 cups of the crumbs and set them aside.
To the remaining crumbs, add beaten egg, 1/2 cup buttermilk, baking powder and baking soda. Mix for 2 minutes.
Add the remaining 1/2 cup buttermilk and beat for an additional 2 minutes.
Pour into the prepared baking pan. Sprinkle the reserved crumbs over the top. Sprinkle with additional cinnamon if you'd like.
Bake for 38-40 minutes or until the center of the cake bounces back when you touch it.
Serve the cake warm.
