Mix cookie mix, graham crackers and butter in a bowl till blended
Put mixture into an ungreased baking dish and form a crust on the bottom
Bake at 350 for 10-15 mins (it will still be soft when you take it out but firm)
Pour nestle morsals on top and let melt for a few minutes then spread to have a layer of chocolate (I am sure left over easter chocolate chopped in a food processor would do just as good too)
top with peeps ( i had 3 lines of 4 but you may need more if you use a bigger pan
put back in oven for 5-7 minutes (you want the peeps to be really really puffy)
Spread to the best of your ability (since peeps are slightly difficult to spread)
