VANILLA CRACK Preheat oven to 350 degrees F., rack in the middle position. 1 box salted soda crackers. (I used Saltines) 2 sticks salted butter (1 cup, 8 ounces, 1/2 pound) 1 cup white (granulated) sugar 2 teaspoons vanilla extract 1/2 cup salted nut pieces Line a 10-inch by 15-inch cookie sheet with heavy-duty foil. If you have a jellyroll pan, that's perfect. If you don't, turn up the edges of the foil to form sides. Spray the foil with Pam or other nonstick cooking spray. (You want to be able to peel it off later, after the cookies harden.) Cover the pan completely with a single layer of soda crackers, salt side up. (You can break the crackers in pieces to make them fit if you have to.) Set the cracker-lined jellyroll pan or cookie sheet aside while you cook the topping. Combine the butter with the white sugar and vanilla in a heavy saucepan. Bring it to a full boil over medium high heat on the stovetop, stirring constantly. (A full boil will have breaking bubbles all over the surface of the pan.) Boil it for exactly five (5) minutes, stirring it constantly. If it sputters too much, you can reduce the heat. If it starts to lose the boil, you can increase the heat. Just don't stop stirring. Pour the mixture over the soda crackers as evenly as you can. Hannah's Note: I start by pouring the mixture in lines from top to bottom over the length of the pan. Then I turn it and pour more lines over the width of the pan. Once the whole pan is cross-hatched with the hot toffee mixture, I pour any that's left where it's needed. If it doesn't cover the soda crackers completely, don't worry--it'll spread out quite a bit in the oven. Sprinkle the salted nut pieces over the top. Slide the pan into the oven and bake the cookies at 350 degrees F. for ten (10) minutes. Remove the pan from the oven and let it cool on a wire rack. When the cookies have thoroughly cooled, peel off the foil and break them into random-sized pieces.
