This is a almost "no cook" dessert. It is easy to make and very good. You might want to adjust the amount of butter (one stick), flour, and chopped pecans for the bottom layer to fit your pan. Also, be sure to let the instant pudding sit and firm up before you spread it on for a layer, otherwise it will be messy.You can use any two flavors of pudding you want, I usually just go with vanilla and chocolate. You don't have to use the name brands, it tastes just as good with the store brand. I got this recipe from a woman in Ohio. It has been a big hit ever since.
