Cake Mix Sour Cream Coffee Cake

Posted in : BREAKFAST on by : Admin

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 lots of cinnamon crumbly goodness. This breakfast cake is an instant crowd pleaser!


  • 1 package yellow cake mix (mix only, not prepared)
  • 1 egg
  • 1 cup sour cream (may sub plain greek yogurt)
  • 1/4 cup butter, melted
  • 1 teaspoon vanilla
  • Crumble Topping

  • 1 1/4 cups flour
  • 2/3 cup brown sugar
  • 1/2 cup sugar
  • 1/2 teaspoon salt
  • 1 teaspoon cinnamon
  • 1/2 cup butter (8 tablespoons), chilled and cut into cubes
  • Instructions

  • Preheat oven to 350 and grease a 9×13 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 the cake batter in the bottom of the greased baking dish. Sprinkle with half of the crumble mixture. Grease a rubber spatula and gently spread the remaining batter over the crumble (this takes a little finessing but it’s worth it if you just work with it – see note). Top with remaining crumble.
  • Bake for 30-35 minutes until an inserted toothpick comes out clean. Serve warm.
