5: Symphony with Almonds and Toffee Chips (Hershey's) - Really smooth, velvety, melt-in-your-mouth milk chocolate with bits of almond and toffee in it. A regular Symphony bar is so rich and smooth that it's great on its own, but when you factor in the crunchy bits, it's downright epic. My favorite is to get a piece and let it melt away, then chew up the remnant almond and toffee.
3: Payday (Hershey's) - Sick of chocolate? Hershey's figured you would be and came up with the Payday bar--soft, chewy caramel covered in peanuts. The best of it? The peanuts are salted! Mmm...
2: Almond Joy (Hershey's) - Chewy and sweet coconut covered in milk chocolate with an almond right on top. It's two half-bars per package--the only way this could be better is if they provided a variety option, letting you get an Almond Joy half-bar and its cousin, a Mounds half-bar (the same coconut, no almond, dark chocolate instead of milk), in the same package. We can dream, right?
1: Twix (Mars) - You get two of them! Sometimes, they are just stale enough that the caramel is a little bit harder than intended, and if you bite it just right, the caramel and and cookie split and you get two distinct candy bars in each stick of Twix. Twix has had multiple variations over the years, but it's never mattered--original Twix is number one.
Man, I look at the list and there are so many missing! But alas, there's only room for five... What would you add?
