Place 18 jello shot cups on a baking sheet or in a baking dish for easy carrying to the fridge. Set aside.
Add gelatin powder and hot water to a mixing bowl or to a 4-cup measuring cup. Stir until dissolved. Allow to cool for 5 minutes before moving on to the next step.
Once the gelatin mixture has cooled a bit, add the Crown Apple. Stir until combined.
Pour into the jello shot cups, then seal each with a lid. Place in the fridge for at least 2 hours or until the gelatin is set.
When ready to serve, garnish with a green apple ring and serve. Enjoy responsibly!
