Ingredients

Scale
  • 1 box white cake mix (plus ingredients listed on box for preparation)
  • 1 cup boiling water
  • 3 ounces red gelatin (like Jello)
  • 3 ounces green gelatin (like Jello)
  • 1 cup cold water (divided)
  • 1 tub (8 ounces) frozen whipped topping, thawed
  • 1/2 cup heavy cream
  • 2 tablespoons powdered sugar
  • 1 teaspoon vanilla extract
  • Christmas sprinkles for topping

Instructions

  1. Prepare the white cake according to the package directions using a 9×13 inch baking pan. Bake until a toothpick inserted in the center comes out clean. Let the cake cool in the pan for 15 minutes.
  2. While the cake cools, prepare the gelatin. In two separate bowls, dissolve the red gelatin in 1/2 cup boiling water in the first bowl, and the green gelatin in 1/2 cup boiling water in the second bowl.
  3. Stir 1/4 cup cold water into the red gelatin mixture, and 1/4 cup cold water into the green gelatin mixture. Set both bowls aside to cool to room temperature, about 30 minutes. Do not let them set.
  4. Use the handle of a wooden spoon or a large fork to poke holes all over the top of the warm cake, spacing the holes about 1 inch apart. Poke all the way through to the bottom of the cake.
  5. Carefully pour the red gelatin mixture evenly over the entire surface of the cake, allowing it to soak into the holes. Let the cake cool completely, about 1 hour.
  6. Once the cake is cool, repeat the poking process over the red gelatin layer. Pour the green gelatin mixture evenly over the cake. Cover the cake and chill in the refrigerator for at least 4 hours, or until the gelatin is fully set.
  7. Prepare the topping: In a medium bowl, beat the heavy cream, powdered sugar, and vanilla extract until stiff peaks form. Fold in the thawed whipped topping gently.
  8. Spread the whipped topping mixture evenly over the chilled, set cake. Sprinkle generously with Christmas sprinkles before serving.

Notes

  • For the brightest colors, use the Jello right after it cools to room temperature, before it starts to thicken too much.
  • You can make this cake a day ahead of time; the chilling time is necessary for the gelatin to set properly.
  • If you want a richer filling, substitute the cold water in the gelatin step with cold clear soda like lemon-lime for extra flavor.
