My grandma used to make this for me every time I visited. I always loved it and finally made some myself. This cake is great to make on a warmer day, because you don't even have to turn on the oven. It only requires 2 ingredients, Chocolate Wafers, and Cool Whip, so that's an added bonus as well!
It's super simple! Grab a loaf tin and your 2 simple ingredients. First, spread 2-3 Tbsp of Cool Whip on the bottom of the tin evenly. Then, add a layer of chocolate wafers. They fit perfectly with 2 across. At the short side of the tin, a whole cookie wouldn't fit, so I added some cookies that were already broken in half.
Keep layering the Cool Whip and Chocolate Wafers until you are out of ingredients. I liked when the layers of Cool Whip were thicker, but whatever you wind up doing will be great! I also crushed up some of the broken cookies (in my fingers) and lightly sprinkled them on top of the cake for a bit of added cuteness!
Pop the "cake" into the freezer, and let it freeze over night. Voila! You have an incredibly easy, no-bake Cookies and Cream Ice Box Cake!
