Ingredients

Scale

Root Beer Layer

  • 2 envelopes Knox gelatin (approx. 4 tsp total)
  • 1/2 cup cold water
  • 1/2 cup boiling water
  • 1/2 cup sugar
  • 2 cups Root Beer (high-quality brand such as A&W or Barq’s)

Ice Cream Layer

  • 3 envelopes Knox gelatin
  • 1/2 cup cold water
  • 1 cup boiling water
  • 1/4 cup sugar
  • 2 cups Vanilla Ice Cream

Instructions

  1. Prepare the Root Beer Gelatin: Sprinkle 2 packets of gelatin over 1/2 cup cold water in a bowl and allow it to absorb and soften for a few minutes. Then, pour 1/2 cup boiling water over the gelatin and stir until completely dissolved. Add 1/2 cup sugar and 2 cups root beer to the mixture, stirring until the sugar is fully dissolved.
  2. Set the Root Beer Layer: Pour the root beer gelatin mixture into a 9×13-inch baking dish. Refrigerate for at least 4 hours until fully set. Once set, cut the gelatin into cubes and transfer them into an 8×8-inch baking dish. Keep refrigerated while preparing the next layer.
  3. Prepare the Ice Cream Gelatin: Sprinkle 3 packets of gelatin over 1/2 cup cold water and let it soften. Then, add 1 cup boiling water and stir until dissolved. Add 1/4 cup sugar and stir well, setting the mixture aside.
  4. Melt the Ice Cream: Place 2 cups of vanilla ice cream in a small pot and melt it gently over medium heat on the stove or use a microwave until fully liquid. Stir the melted ice cream into the gelatin mixture thoroughly and let it cool to room temperature.
  5. Combine and Chill: Pour the ice cream gelatin gently over the root beer gelatin cubes in the 8×8 baking dish. Refrigerate overnight or until completely set.
  6. Serve: Once set, cut into cubes and serve this delightful root beer float jello for a fun, no-melt dessert treat that resembles the classic root beer float flavors.

Notes

  • Use a high-quality root beer like A&W or Barq’s for the best flavor.
  • Allow the gelatin mixtures to cool to room temperature before combining layers to prevent melting.
  • This dessert can be made a day ahead and stored in the refrigerator.
  • For easier serving, cut into bite-sized cubes before chilling the ice cream layer.
  • The recipe yields about 24 servings, perfect for parties or gatherings.
  • If desired, garnish with whipped cream or maraschino cherries for extra festivity.
