My second recreation of a Christina Tosi / Milkbar recipe (following Cinnamon Toast Cruch Cereal Milk Ice Cream which I used for my niece's Cinnamon Toast Cruch themed 1st birthday cake a while back). Crack Pie is a very buttery and sweet pie in an oatmeal cookie crust. You can really only eat a sliver and even then it needs some coffee to wash it down -- so an excellent sugary breakfast starter, but I'd go with something else for actual desert.
Instead of a full pie, I made little mini versions in my mini tart pans and they came out just fine -- literally, as I'd been thinking they'd get stuck but that wasn't a problem. (Probably because my tart pans have removable bottoms -- the bottom of the pie need some knife coaxing.)
I don't know which recipe I used, but there are a bunch out there all based off the original, which has been published. I didn't have Powdered Milk so I instead used a bit of milk and cornstarch, then I upped the cornstarch a bit more (like half a teaspoon extra) and ended up with something that set nicely even without chilling, which meant I could dig in less than an hour after baking.
