Martha's chess tart is an easy riff on the classic Southern dessert, chess pie. It has a cookie-crumb crust made with Nilla wafers, rather than the usual pastry shell—no rolling dough is needed. And it’s shallower than a chess pie, so the resulting dessert, with a sweet cookie crust and a gooey, custard filling made with two sugars, is almost like a candy bar. A little cornmeal (just a tablespoon) gives the filling a slight crunch.
Let the pie chill in the refrigerator before you enjoy it and cut thin slices, because it's very tasty, but also very rich.
Directions
-

Press cookie-crumb crust into prepared pan:
Press mixture into bottom and up sides of pan. Refrigerate until set, about 15 minutes.

Bake crust:
Transfer pan to a rimmed baking sheet, and bake until tart shell is golden, about 12 minutes. Let cool slightly. Reduce oven to 325°F.
-
Make filling:
