First take 2 tbsp of champagne into a small bowl. Sprinkle gelatin on top and let it sit for 10 minutes.

Pour the rest of the champagne and sugar into a small pot over medium heat, stir until sugar completely dissolved. Then add gelatin mixture and stir until gelatin completely dissolved. Remove pot from heat and allow to cool for 10-15 minutes.

Pour the mixture into prepared cups. Divide the amount evenly into each cup/glass. Carefully transfer the cups into the refrigerator and chill until the jello is set (at least 5 hours).

When the champagne jello is set, prepare vanilla panna cotta layer. Pour milk into a small bowl and sprinkle gelatin on top. Let it sit for 10 minutes.

In a small pot, heat heavy cream, vanilla extract, and sugar on medium heat, stir until sugar completely dissolved. Then add gelatin-milk mixture and continue stirring until gelatin completely dissolved. Remove from heat and allow to cool to room temperature.

Take the champagne jello cups out of the refrigerator. Carefully pour and divide panna cotta mixture into the cups. Transfer cups back to the refrigerator and chill until panna cotta layer is set (at least 5 hours).

Dip or brush the edges of the cups with corn syrup. Then dip the edges into a bowl of gold sprinkles. Refrigerate until ready to serve.
