Oreo Treat Box (picked up a couple at Aldi a while back)
Follow the directions for each step on the treat box. I did the cookie crust first, then a layer of the cream filling. I then alternated pudding/cool whip/cookie crumbs (twice to fill my bowl). On top I layered with oreos and I was done. Once again, my trifle saved me with an easy dessert under $10.
