As fun to say as it is to eat:
Let's be honest here. You can make this recipe the long and (probably) more delicious way, or you can make it in about 4 minutes. I think it's safe to say I did it the short route, and used a store-bought crust, a can of dulce de leche and a bowl of frozen whipped cream. And you know what? It was good.
Would I take the time to make it the "right" way in the future? Sure. But if I am in need of something quick and easy, I'm totally okay with going the short route again.
