A note about mixing fatCoffee pops: use HOT brewed coffee or tea, because that will mix more thorough with the fatCoffee.
Even still, as the pops cool in the freezer, the foamy part will float to the top before the pops freeze completely. This means that your popsicles will have a richer, smoother part at the bottom of the stick, and a icier part at the top. We rather like it that way, but you should judge for yourself.
One possible way to make a more evenly-mixed Butter Coffee Pop with fatCoffee is to use these Ice Pop Molds instead. About a 1/2 hour after putting them in the freezer, take them out and mash them like you would a sealed fatCoffee packet to mix the material around. Even better, lay them flat in the freezer so that the icey and smooth parts are distributed evenly along the length of the pop. We’ll be trying that this weekend!
