In a microwave-safe bowl, add the green apple jello, unflavored gelatin, and water. Stir gently to combine and let it sit for 5 minutes to give the gelatin time to bloom. Microwave it for 15 seconds, and stir gently. Microwave for another 15 seconds and stir. If the mixture is not melted, continue in 5-second increments until melted. (See note)
Let the mixture sit for 10 minutes. After 10 minutes, there will be a layer of foam on top. You should be able to easily scoop the foam off the surface with a spoon.
Spray the tray with a little cooking spray. Pour about half the mixture into the bottom of a tray. Let it sit in the fridge for about 3-5 minutes or just until it starts to set.
Unwrap about 10 pieces of caramel and roll it out about ¼ inch thick. Cut out circles and set them aside. Arrange the caramel cutouts on top of the first layer. (See note) Microwave the remaining mixture for about 10 seconds in order to pour it over the caramels.
Let the gummies sit in the fridge for 1 hour. Cut out your gummies and add the lollipop sticks. (See note) Lay them on a baking sheet lined with parchment paper and put them back into the fridge for another 3 hours until they set.
In a small bowl, add the sugar and citric acid. Mix just until combined. Roll the gummy cutouts or lollipops in the sugar mixture and enjoy!
