So you have way too much candy leftover from tonight's Halloween extravaganza. Well, I don't really consider candy "leftover" since you can just keep it around the house for months and munch on it, but stay with me here.
Squidboo has several recipes for stuff you can make with the stuff you got tonight, including Apple Candy Bar Salad, which sounds like...well, everything you have in your bag thrown together into a dessert (with apples!). You can also make Butterfinger Layer Cake, Candy Bar Cookies, and Fudge. CD Kitchen has a bunch of recipes too, including Baby Ruth Cookies and Cannonball Cake.
I wouldn't advise making these before you go to bed tonight though. Wait for the weekend.
