Oreo Ice Cream Cake. Easy to make, just need to make it a day ahead so it can freeze.
Oreos (crushed fine), you should need most of one package.
1 1/2 gallon container vanilla ice cream (try to get one in an old fanshoned cardbord "box", if you can, it's easier to deal with)
1 container cool whip (you'll need one of the larger sized tubs)
1 can Hershey's sryup
9x13 or similar sized pan (mom always used metal, not sure how glass would work)
Use crushed oreos as a bottom crust, pushing down to make firm. Take ice box completely appart and slice ice cream into slices of roughly equal thinkness, and place in pan in a single layer (if you have a tub of ice cream, just do your best to make slices) taking care that there are some small gaps between slices. Take can of syrup and pour all over ice cream layer (some of the syrup will soak down between the seams in the ice cream, this is a good thing, it gets into the crust this way), you'll use most if not all of the syrup. Take cool whip and "frost" the top of the "cake", make it a good 1 inch or more in depth. Take some more crushed oreo and sprinkle over top. Cover with foil, freeze overnight, and enjoy!
