I had these tasty treats at a birthday party for a friend's son. Oh. My. Word. Yum!
So, since I made an extra-big batch of coffee this morning and only drank one cup, guess what's going in my fridge for later!
Thanks for the inspiration, PW & Daisy!
*EDITED TO ADD*
So, I made them and YUM! I used my pint jars (2 cups for those non-canners out there) and that gives me 8 ounces of yummy caffeine goodness.
