Combine all of the ingredients in a high-speed blender, and blend until silky-smooth and creamy. Taste the mixture to see how you like the taste-- you can easily add more sweetener or coffee to suit your taste. Pour the mixture into your favorite ice pop mold (I use this one), insert popsicle sticks, and freeze until set, about 4 to 6 hours.
To remove the ice pops from their mold, fill your sink with hot tap water and place the mold in the hot water bath for 15-30 seconds, just until the pops easily slide out. Serve frozen, and store the extra pops in a sealed container in the freezer.
