This easy crumb cake with cake mix combines a moist yellow cake with a buttery, generous crumb topping for a New York style crumb cake perfect for breakfast, lunch, or any occasion.

Ingredients
 

  • 15.25 ounce yellow cake mix
  • 3 large eggs or as called for on the box
  • 1 cup water or as called for on the box
  • ½ cup vegetable oil or as called for on the box
  • 4 ¼ cups all-purpose flour
  • 1 ½ cups melted butter cooled to room temperature
  • 1 cup granulated sugar
  • ½ cup light brown sugar
  • 2 Tablespoons ground cinnamon
  • 4 teaspoons vanilla extract
  • confectioners sugar optional topping

Instructions

  • Preheat oven and prepare cake batter as per package instructions. Coat a 9x13 pan with non stick cooking spray and bake cake for 5-7 minutes less than called for on the box.
  • While the cake is baking, prepare the crumb topping. Use a fork to combine the flour, sugar, butter, cinnamon, and vanilla extract in a large mixing bowl. It should be crumbly.
  • Remove the cake from the oven. Starting at the edges and working toward the center, sprinkle the crumb topping evenly over the top of the cake.
  • Return to the oven to bake for 10-12 minutes, or until baked through and crumb topping has slightly browned.
  • Cool on a wire rack for at least 30 minutes. Sift confectioners sugar over the top (optional) before slicing and serving.

Notes

  • I used Duncan Hines yellow cake mix but any cake mix suitable for a 9x13 will work. I’d avoid Betty Crocker since they dropped weight to 13.25 ounces.
  • If the crumb mixture is too wet, add a spoonful more flour as needed to get the right consistency. 
  • This cake has a very generous layer of crumb topping. For a less indulgent treat you can halve the crumb mixture.
