Like toria mentioned this recipe has a lot of chatter. What the heck is corn powder? Can I use cornstarch? What on earth is milk powder? Why is there so much sugar? Wait is it supposed to run all over the place? Must I have a stand mixer? Why do so many "authorized" recipes, Bon Appetit, L.A. Times, and even
Chang & Tosi's visit with Martha Stewart fails to mention corn powder?
I had looked at Milk Bar's book for years but could never bring myself to make anything from it. There were so many steps. Nothing had ready-to-hand ingredients, yep glucose, cake rings, and acetate strips come to mind. And things just sounded odd, WTF cereal milk recipes!
But after having a toodler's portion of Crack Pie at dessert exchange a couple of weeks ago and quite a bit of cheering from kalamazoogal I decided to give it a try. I was buoyed because I had all of the ingredients ( did I buy milk powder years ago for this recipe?) and decided to break the recipe up. BA's version said it takes about 15 hours!
First I made the crust. The crust is made from a giant, buttery, oatmeal cookie.

Next you crumble that cookie, add sugar, salt, and melted butter then press into the pie pan.

I made the giant cookie the first day. And the only problem was not eating the cookie!
The next day you make a filling that includes milk powder, corn powder, sugar, yolks, cream, and butter. Pour it into the prepared pie pan and bake until golden while being simultaneously firm on the outer edges and
jigglyin the center. Did I mention part of the baking happens with the oven door open in order to hasten temperature drop?
After cooling for a few hours on a rack. You place it in the freezer for at least a few hours. It can be stored up to a month in the freezer. Place it in the fridge for one hour before serving. I don't like powdered sugar so I sprinkled it with home ground sugar.
The filling was not gooey at all. It was very firm and it took some effort to cut. The recipe says to serve the pie cold. But even after being out for a few hours it did not loose its firmness. I watched one person go back for seconds ( I did not watch myself but I did go back for the tiniest sliver as well). One said it was too sweet and binned it proclaiming she had to watch her carbs. And everyone else quickly gobbled it.
A couple of hours later there was one slice left and that was whisked away.

This is sweet, decadent, and salty +toasted butterscotch goodness.
