Step 1

Preheat the oven to 350°F and lightly spray a 9x13-inch baking dish with nonstick cooking spray. In large bowl, mix together the cake mix, pumpkin, and eggs for about 2 minutes. Spread the batter evenly into the prepared dish.

Step 2

Make the crumb topping by whisking the flour, sugar, salt, and cinnamon together in a medium bowl. Slowly drizzle in the butter, stirring with a fork, until a crumb forms and all of the butter has been added. Sprinkle the crumb mixture over the cake batter.

Step 3

Bake for 30 to 35 minutes or until a toothpick inserted into the center comes out clean. Allow to cool, then slice and drizzle with the caramel sauce before serving.
