  • 15 oz yellow cake mix one box
  • 2 1/2 cups quick-cooking oats
  • 3/4 cups butter melted

  • Mix cake mix and oats in a large bowl.
  • Add melted butter, stir until crumbly.
  • Press down half the crumbs onto the bottom of the pan.
  • Combine preserves and water, spread over crumbs. If preserves are already easy to spread, you don't need to add the water.
