I used two (rolls?) of chocolate chip cookie dough and a half gallon of ice cream.
Greased the pan and spread the cookie dough on the baking pan.
Baked the cookie in the oven. I was nervous about this because I never baked cookies before
Especially one around 1 foot in diameter.
After the cookies were done, I shoveled a half gallon of ice cream between the two cookies, wrapped it in plastic wrap and placed it in the freezer. The cookie pretty much fed us for two days straight.
