Pour the powdered jello, gelatin and water into a small saucepan, and let sit for 5 minutes until the gelatin softens. Place the saucepan on the stove and set it to medium heat. Fully dissolve the jello and gelatin in the water while stirring, about 5-10 minutes.
Pour the liquid into a container with a spout, and then pour it into heart-shaped molds, filling them halfway. Place this in the fridge while you make the white layer. This layer will set in the meantime.
In the meantime, pour the water and gelatin into a small saucepan and let sit for 5 minutes. Place the saucepan on the stove and set it to medium heat. Fully dissolve the gelatin, then remove from the heat and add the condensed milk. Mix well.
Pour the liquid into a container with a spout and pour it on top of the coloured hearts. Return the mold to the fridge for 1 hour for the gummies to fully set.
Unmold and enjoy!
