Me, I love choco-biscotti, so I sometimes get bite-sized stuff like this:
TBH, I haven't really found the perfect chocolate-combo yet.
I do like combining dark chocolate pieces with toasted almonds as a (mostly) healthy snack. Still, I feel like there's something probably better out there..?
I like the ones with wafer inside, like Kit Kat or Coffee Crisp. Tim Tam is the best though, especially the dark chocolate variety. Especially especially if you use it in a Tim Tam Slam.
