Cake Mix Sour Cream Coffee Cake

By srumbel

Sour cream makes this coffee cake super moist and the best part is that it starts with a cake mix. It's so easy to make, and loaded with a double layer of cinnamon crumbly goodness. This breakfast cake is such a crowd pleaser!

Preparation

Step 1

Preheat oven to 350 and grease a 9x13 inch baking dish with cooking spray.
First prepare the crumble. Whisk together flour, brown sugar, sugar, salt, and cinnamon. Cut in chilled butter until crumbly. Set aside.
Next prepare the cake. Combine cake mix, egg, sour cream, melted butter, and vanilla and mix until combined. It's okay if the batter still has some lumps.
Spread half of the cake batter in the bottom of the greased baking dish. Sprinkle half of the crumble mixture on top of the batter. Add remaining batter, spread evenly, then sprinkle with remaining crumble mixture.
Bake for 30-35 minutes until an inserted toothpick comes out clean. Serve warm.
