I saw a video showing how to do this on the Duncan Hines site. I tried it with a spice cake mix and had great results!
1 spice cake mix (or yellow)
3 egg yolks
1 whole egg
1 Tbsp butter, softened
Mix all of the ingredients with your hands. Fold it multiple times until all the ingredients are incorporated. Roll out the dough on a floured surface. Place in a pie pan. I filled my pie with my apple pie filling and crumb topping, but you could fill with anything. (http://workingmomwonders.blogspot.com/2013/10/dutch-apple-pie.html)
Bake the pie at 350 degrees for about 30-40 minutes.
I cut the extra dough into strips and sprayed them with cooking spray. Then I topped with cinnamon and sugar and baked for about 12 minutes. They were delicious too.
