Ingredients

Scale
  • 1 box white cake mix plus ingredients listed on box (eggs, oil, water)
  • 1 cup boiling water
  • 1 (3 ounce) package red gelatin (Jello)
  • 1 (3 ounce) package green gelatin (Jello)
  • 1 cup cold water
  • 1 (14 ounce) can sweetened condensed milk
  • 1 teaspoon vanilla extract
  • 1 (8 ounce) container frozen whipped topping, thawed
  • Red and green sprinkles for topping

Instructions

  1. Prepare the white cake according to the package directions, using a 9×13 inch baking pan. Bake and let it cool slightly on a wire rack.
  2. While the cake is still warm, use the handle of a wooden spoon or a large fork to poke holes all over the top of the cake, about 1 inch apart.
  3. In a separate bowl, dissolve the red gelatin in 1 cup of boiling water. Stir for 2 minutes until completely dissolved. Stir in 1/2 cup of cold water. Pour this mixture evenly over the warm cake, letting it soak into the holes.
  4. Chill the cake in the refrigerator for at least 1 hour, or until the red gelatin is mostly set.
  5. Repeat the gelatin process with the green gelatin: dissolve it in 1 cup of boiling water, stir in the remaining 1/2 cup of cold water, and pour evenly over the set red layer.
  6. Return the cake to the refrigerator and chill for at least 2 more hours, or until the green gelatin is completely firm.
  7. In a small bowl, whisk together the sweetened condensed milk and vanilla extract.
  8. Spread the whipped topping evenly over the chilled, set gelatin layers.
  9. Decorate the top with red and green sprinkles before serving.
  10. Keep the cake refrigerated until you serve it.

Notes

  • For extra flavor infusion, you can substitute the cold water in the gelatin mixture with vodka or white rum, but skip this step if serving to children.
  • If you want a thicker topping, use 1 cup of heavy cream whipped with 1/4 cup of powdered sugar instead of the frozen whipped topping.
  • You can make this dessert a day ahead of time to let the flavors fully meld.
