Preheat oven to 350 degrees F. Prepare a 9 x 13 baking dish by lightly coating with cooking spray, set aside.

Slightly beat eggs, and add pumpkin, milk, sugar, cinnamon, ginger, nutmeg, and cloves. Stir to combine and pour into prepared baking dish.

In a separate bowl, combine melted butter, gluten free cake mix, and chopped nuts. Using your fingers, crumble this mixture over the top of the pumpkin mixture. It will not cover the entire top, but gently crumble it over the top, making sure to disperse it over the entire pumpkin dish.

Bake for 1 hour or until toothpick comes out clean. Remove from oven and cool.

Serve with whipped cream or ice cream if desired.
