(luckymommyto2boys ~ Amy)

1 (18 ¼ ounce) package yellow cake mix
4 eggs (divided)
¾ cup margarine (divided)
1 (29 ounce) can pumpkin puree
½ cup white sugar
1 ½ teaspoons ground cinnamon
2/3 cup evaporated milk
1 cup brown sugar

Preheat oven to 350 degrees F (175 degrees C). Grease and flour a 9x13 inch pan. Reserve 1 cup of cake mix from the package. In a bowl, combine remaining cake mix, 1 egg and ½ cup melted margarine. Press mixture into the bottom and up the sides of a 9x13 inch pan to form a crust.
Mix together the pumpkin, 3 eggs, sugar, cinnamon and evaporated milk until blended. Pour over the crust. Combine the brown sugar and reserved 1 cup cake mix, then cut in the ¼ cup margarine until mixture is crumbly. Sprinkle over the filling.
Bake in the preheated oven for 50 minutes. Refrigerate overnight before serving.
