PREPARATION
Make the coffee jello:
In a medium bowl, stir gelatin into cold coffee and let stand 10 minutes until softened. Add hot coffee, sugar, and salt, and stir until completely dissolved.
Pour into a 9×13-inch baking dish and refrigerate until firm, at least 4 hours. Once chilled, cut into cubes and transfer to an 8×8-inch baking dish. Chill while you make the ice cream layer.
For the ice cream layer:
Sprinkle 3 packets of gelatin over cold water and let sit until softened. Pour boiling water over and stir until dissolved. Stir in sugar and set aside.
Place the 2 cups of ice cream in a small bowl. Microwave until it’s liquid. Stir the melted ice cream into the gelatin mixture, and let it sit until it comes to room temperature.
Pour the ice cream mixture over the coffee cubes in the baking dish and chill in the refrigerator overnight. Cut into cubes and enjoy!
