Grease a bread loaf pan with non-stick cooking spray and set aside.

To a medium saucepan, add the lemon juice, 1 cup of the prosecco and white sugar. Mix until combined.

Sprinkle the gelatin overtop the champagne mixture. Let sit for 2-3 minutes, this will allow the gelatin mixture to bloom.

Turn the stove on to low heat for 3-4 minutes, mixing occasionally to dissolve the gelatin.

Once fully dissolved, place saucepan in fridge to allow the mixture to completely cool.

Stir in the vodka and remaining champagne and pour into the prepared loaf pan. Let set overnight, or at least for 3-4 hours.

Once they're set, run a knife along the edge of the pan. Flip the pan upside-down onto a cutting board and cut into 18 squares using a sharp knife.

Top with edible gold glitter or gold sprinkles. Enjoy!
