Sex in a Pan (aka 5 layered dessert)

This is an amazing dessert- and super quick and easy to make as well.  It's been known as "Better than sex", "Sex in a pan" or if those names make you blush you can call it "5 layered dessert" like my mom does :)

Layer 1:
1 cube butter- melted
1 c. flour
1 c. walnuts
mix together, press into baking pan and bake at 350 for 10 mins. Let cool.

Layer 2:
8 oz cream cheese
1 c. cool whip
1 c. powdered sugar
mix until smooth, spread over crust. (I do it when the crust is still warm so it will spread easier)

Layer 3:
1 large box instant vanilla pudding
2 c. milk
mix together and pour over layer 2.
(for this layer, this time I substituted banana cream pudding and sliced fresh bananas on top of it- it turned out great!)

Layer 4:
1 large box instant chocolate pudding
1 1/2 c. milk
mix and pour over layer 3.

Layer 5:
spread cool whip on top and sprinkle shredded chocolate on top if you want.

*hint*  For the pudding layers I pour them in before the pudding is fully set up- it will be runny but will go on more evenly and set up after you pour it on.
