Holiday Pumpkin Cake

1 large egg
reserve one cup, use the rest yellow cake mix
1 stick butter
2/3 cup brown sugar
2/3 cup sweetened condensed milk
large can Libby's pumpkin pie mix
1 tablespoon cinnamon
2 large eggs
half a stick butter

In a medium sized bowl, mix together 1 egg, 1 melted butter stick, and yellow cake mix. Before you mix in the cake mix, reserve one cup and put it aside.(You will use it later)Then mix all these ingredients together. You should have a yellow-colored mix. Press this into a 9x13 glass pan. Then in a seperate bowl, pour in the can of pumpkin, the sweetened condensed milk, the brown sugar, the 2 eggs, and the cinnamon. Mix these together-you should have a large amount of thick liquidy orange mix. Pour this on top of the bottom layer of cake. Now take the cake mix you set aside. Pour it in a small bowl and take half a stick of butter. Heat the butter for about 10 seconds so it gets soft-but don't melt it!Then mix these ingredients with a spoon or with your hands. When it is weel-mixed together, spread it evenly on top of the pumpkin. Then set your oven to BAKE-350 degrees for about 20+ minutes. Be sure to check up on your cake from time to time so it doesn't burn. When it looks done(the top will look baked) take it out and let it cool.
