DillDoe has a neat recipe for making highly-caffeinated chocolate treats. The only ingredients are semi-sweet chocolate and coffee beans. From the HOWTO:
The chocolate does a great job in masking/integrating the coffee taste. It kinda taste like crunchy Oreo cookies crumbs covered in chocolate. The first batch I made (about 9 pieces) I ate while watching TV cause it tasted so good I couldn't stop eating it. Big mistake cause it kept me up almost all night. So if you need to pull an all nighter than go ahead and pig out!
