Empty the blue Jell-O package into a small bowl and mix with 1/2 cup boiling water until the powder is completely dissolved. Allow to cool for 5-10 minutes then add about 1/2 cup vodka if using.

Prepare the disposable cups by placing one in each muffin tin tilted on one side.

Divide the blue Jell-O evenly between the cups. Place in the refrigerator for 15-20 minutes or until set.

Prepare the white layer by mixing one packet of unflavored gelatin in a small bowl with ¼ cup milk. Heat remaining milk in a small saucepan until hot but not boiling. Add the sugar, vanilla extract, and ½ cup vodka if using. Combine the warmed milk mixture with the gelatin milk mixture and whisk to combine.

Flip each of the disposable cups to the opposite side of the muffin tin. Evenly pour the white Jell-O layer over the blue. Place back into the refrigerator until set.

Empty the red Jell-O package into a small bowl and mix with 1/2 cup boiling water until the powder is completely dissolved. Allow to cool for 5-10 minutes then add about 1/2 cup vodka if using.

Set the cups upright in the muffin tin, and evenly divide the red Jell-O over top of the white layer. Allow to set in the refrigerator for 3-4 hours or until completely set.

Once you are ready to serve, top with whipped cream and edible gold stars!
