In a bowl, whisk together the lemon-flavored gelatin with 1 cup of boiling water until the gelatin is completely dissolved.

Stir in 1/2 cup of vodka into the lemon gelatin mixture.

Pour the mixture into shot glasses, filling up to half. Chill in the refrigerator until set, about 2 hours.

In a separate bowl, whisk together the orange-flavored gelatin with 1 cup of boiling water until the gelatin is completely dissolved.

Stir in 1/2 cup of vodka into the orange gelatin mixture.

Carefully pour the orange gelatin mixture over the set lemon layer, filling the shot glasses to the top. Chill in the refrigerator until set, about 2 hours.

Top each shot with whipped cream and Halloween-themed sprinkles before serving.
