This is not a cookie so please forgive me but I saw this on Live with Regis and Kelly this morning, it was the first that I had ever heard of it, but it looked so good. I found a recipe online. It is a Crack Pie and here is the recipe. The one on the show this morning looked like they sprinkled powder sugar on it after it was baked.
Ingredients
1 9" unbaked pie shell
1 cup granulated sugar
3/4 cup packed light brown sugar
1 tablespoon fine cornmeal
5 eggs
1/3 cup whipping cream
1 tablespoon cider vinegar (optional)
1 teaspoon vanilla extract (optional)
1/2 cup melted butter
Directions
Combine granulated sugar, light brown sugar, and corn meal.
Beat in eggs one at a time.
Stir in whipping cream, cider vinegar, vanilla extract, and melted butter.
Pour into unbaked pie shell.
Bake on middle rack at 400 F for 10 minutes. (this helps create the CRACK)
Lower heat to 325 F and continue baking for 45 minutes more.
