Pour the boiling water into a bowl containing your blue Jello powder and whisk the mixture until the powder is completely dissolved.
Pour in 1/2 cup cold water and whisk until combined.
Pour in the vodka and whisk until thoroughly blended. Divide the Jello mixture evenly among 22 two-ounce shot cups, then chill for at least one hour.
FOR THE WHITE LAYER:
Place the cold water in a pan and sprinkle the gelatin over it. Let the mixture sit for 2-3 minutes.
Transfer the pan to the stove and cook on low heat for 4-5 minutes until gelatin has melted.
Remove the mixture from the heat, then whisk in the condensed milk.
Let the mixture cool for 10 minutes, then add a layer of white Jello on top of the blue Jello. You may have some white gelatin leftover, which you can pour into a bowl and chill separately for a snack!
Chill for at least one hour.
FOR THE RED LAYER:
Heat one cup of water until it’s boiling.
Pour the boiling water into a bowl containing your red Jello powder and whisk the mixture until the powder is completely dissolved.
Let the mixture cool for 10 minutes. Add a layer of red jello on top of the white jello in each cup. Chill for at least one hour, or until all layers are set.
FOR GARNISH:
Pipe or dollop a tablespoon of whipped cream onto each shot.
Add some red white and blue sprinkles, then serve immediately.
Notes
Make sure each layer is set before adding the next color so the layers don’t run together.
Add the whipped cream and sprinkles right before serving.
Strawberry Jello is preferred, but cherry or other red flavors work too.
