In a medium bowl, combine cake mix, egg, melted butter, and applesauce.

Stir until well-blended, and press evenly into the bottom of a greased 9x13 pan.

Sprinkle with half of the M&M's®, and press them lightly into the dough.

In a large mixing bowl, beat cream cheese until smooth.

Add the eggs, one at a time, beating well after each addition.

Add the pumpkin puree, pumpkin pie spice, and powdered sugar, beating until smooth and blended.

Pour the pumpkin mixture over the cake mix layer.

Sprinkle with remaining M&M's®.

Bake at 350 degrees for 25-30 minutes, or until edges are golden brown and the center is set. Do not overbake.

Remove from heat to a wire rack to cool completely. Cut into bars. Enjoy!
