Okay, so I finally ended up making these last week (and again, I halved the recipe - still made a ton - and used 1 Tbl. espresso powder instead of 1 1/2 Tbl. coffee powder) and OH. MY. G*D.!!!
These really are to die for, so to all of you chocoholics: make these soon!!
Just wanted to thank the original poster for the recipe question and for all of the responses about it - you all motivated me to try these and they weren't even on my radar last week!
