I'm not really sharing anything wonderfully novel or creative because icebox cakes have been around forever and it's the best this-is-homemade-but-I'm-cheating recipe ever. It's not even really a recipe. It's just an assembly. But, it's delicious and awesome for summertime because it requires zero interaction with stovetop and/or oven and it's supposed to be served cold. It's like revenge. However, I'm still sharing this
9 oz. package of chocolate wafers
1 pint whipping cream
1-1/2 tablespoons powdered sugar
1/2 teaspoon vanilla extract
+ crushed wafers, sprinkles, chocolate shavings, and/or any other decoration you like
If you're going the homemade route, just pour your cream, sugar, salt, and vanilla into a bowl and whip it until you have fluffy peaks that are thick and spreadable. Be certain not to over whip because you'll end up with butter. Butter is great, but it's not what we're going for here.
H&M). If you don't have a mini cakestand, just use a small plate. I layered three wafers on the bottom, spread them with a generous amount of whipped cream, and then stacked three more wafers on top, offsetting them. Then, I spread on more whipped cream and continued until I used up all of my whipped cream and wafers. Make sure that each wafer has a generous slathering because the moisture from the whipped cream is going to soak into the wafers and make them soft and cake-like. If there isn't enough cream, you'll end up with some crunchy bits of wafer.
