Chocolate Cake

  • 1 box chocolate cake mix {15.25 ounce}
  • 3 eggs
  • 1 cup water
  • ½ cup butter {melted}
  • ¼ cup sour cream

Chocolate Crumb Topping

  • cup granulated sugar
  • 1 cup brown sugar
  • 1 teaspoon cinnamon
  • 1 cup butter {melted}
  • ¼ cup cocoa
  • 3 cups all purpose flour


  1. Preheat oven to 350 degrees and spray a 9x13 pan with non-stick spray {set aside}.

Chocolate Cake

  1. Combine the chocolate cake mix, eggs, water, melted butter and sour cream in a medium bowl and mix until everything is combined well. {I used a hand held mixer} Pour batter into prepared 9x13 pan and spread into an even layer.

Chocolate Crumb Topping

  1. In a small bowl combine all of the crumb mixture ingredients.  Work the mixture together into small crumbs using a pastry blender {or fork}.  Don't over work the mixture or you will get a paste and it will change the texture.  Sprinkle the crumbs in an even and thick layer over the top of the chocolate cake batter. Bake for 35-40 minutes.

  2. Remove your Chocolate Crumb Cake from the oven and serve warm or let the cake cool completely and cover. Cake will stay moist for 3 days at room temperature or 4-5 in the refrigerator. It also freezes for up to 3 months.
