Easier than you could possibly believe! The hardest part was finding popsicle molds. After checking at Target (online only) and Bed Bath and Beyond (too expensive for an experiment) I went to my neighbor Sharon. She has 2 daughters out of college and, as I suspected, at the back of a bottoms kitchen cabinet was a classic set of Tupperware molds. SCORE! I wish I got a photo of her later in the day eating one of these yummies – it was after 5pm and still over 90 degrees; she looked like a happy kid.
Melt 5 ounces of semisweet chocolate in 1/2 cup of strong coffee or espresso. (I used cold brew concentrate) this took 8 minutes in my microwave at 50% power. Just bring it up to really soft and then stir until liquid. Add 2 teaspoons of corn syrup or honey to minimize crystals when freezing, a teaspoon of vanilla and a pinch of kosher salt. Pour into molds and freeze. There was enough for 8 popsicles. With only 6 molds in the set, I used 1/4 cup silicone prep bowls for the rest.
