Ingredients

Scale
  • 1 can (15 oz.) pure pumpkin
  • ½ cup brown sugar
  • 1 cup rolled oats
  • 1 teaspoon pumpkin pie spice
  • 1 box (15.25 oz.) yellow cake mix
  • ¾ cup melted butter

Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan with cooking spray.

  4. Sprinkle the dry cake mix over the pumpkin base.
  5. Scatter the oats evenly on top of the cake mix.
  6. Drizzle the melted butter across the surface, making sure to cover as much as possible.
  7. Bake for 40–45 minutes, or until the top is golden brown and crisp.

• Melted butter is key to a crisp topping.

• Don’t mix the cake mix with eggs—just sprinkle it dry.

• Add chopped walnuts or pecans to the oat topping for crunch and richness
