I've made this every years since I first got the recipe, in fact, I made it this morning.

Mix the pumpkin, eggs, milk, sugar and spices together, and spread into a large cooking pan (I use a 9x13 glass cake pan). Sprinkle the cake mix over the top, and place whole pecans evenly on top. Pour the melted butter over entire surface and bake at 350 for 60 Minutes.

It's very Yummy!
