Fudgy Oreo Ice Cream Cake

My friends Kato & Kim are serving as missionaries to Native Americans in Arizona. Kim has a recipe corner in their newsletter, and she shared this recipe, which I've adapted here. I've served this on 2 separate occasions. It's easy to put together and fun to serve and eat. It'd be a refreshing treat on a hot summer day, and even a fun birthday cake. I'm a dork, so I never think of taking step-by-step photos, or even a good finished product photo, but here's a half-gone photo for you:

Still looks delicious!

Fudgy Oreo Ice Cream Cake
1/2 cup fudge ice cream topping, warmed
1 large tub (16 oz.) Cool Whip, thawed
1 pkg. (4 serving size) chocolate instant pudding & pie filling
8 Oreo chocolate sandwich cookies
16 vanilla ice cream sandwiches

Pour warmed fudge topping into medium bowl. Stir in 1 cup Cool Whip until blended. Add dry pudding mix. If too thick to spread, stir in a little bit of milk. Chop Oreo cookies into chunks, stir into pudding mixture. Arrange 6 ice cream sandwiches side by side in bottom of large loaf pan (I used a disposable loaf pan) or on a large piece of foil. Top with half of the pudding mixture. Repeat layers, adding extra ice cream sandwiches, if needed. End with a third layer of ice cream sandwiches on top layer. Frost top (and sides, if you didn't use the pan) with remaining Cool Whip. Cover loosely with foil and freeze at least 4 hours. Let stand at room temperature to soften slightly before serving, or slice with knife dipped in hot water. Makes 16+ servings.
