This Layered Christmas Jello Recipe has colorful layers of cherry and lime Jello with a creamy white filling in between. A family favorite that's perfect for Christmas dinner, holiday parties, and making ahead!
To prepare the white filling, bring 2 cups of milk to a boil. Stir in 1 cup of sugar until dissolved.
In a small bowl, combine ½ cup cold water with 2 envelopes of unflavored gelatin. Add the gelatin mixture to the warm milk and stir to combine.
Place the sour cream in a separate bowl. Slowly stir in the milk mixture until smooth, then add the vanilla extract.
Prepare the first package of Jello using 1 cup boiling water and ½ cup cold water. Stir until completely dissolved.
Pour into the prepared baking dish and refrigerate until set but still slightly tacky to the touch, about 20–30 minutes.
Gently pour 1 ½ cups of the white filling over the Jello layer. Refrigerate until set. Prepare the next package of Jello using the same water measurements, and allow it to cool before gently pouring over the white filling. Continue alternating Jello and filling, allowing each layer to set before adding the next.
Refrigerate until fully set and ready to serve. Cut into squares and enjoy!

Notes
Jello Flavors: I typically use cherry and lime for Christmas, but strawberry, lemon, or other flavors work too. Change the colors to fit different holidays!
Water Measurements: Use 1 cup boiling water and ½ cup cold water for each 3-ounce box of Jello, rather than following the package directions.
Setting the Layers: Each layer should be set but slightly tacky before adding the next. Pour gently to keep the colors from mixing.
Make Ahead: Prepare 1-2 days in advance and keep covered in the refrigerator until serving.
Storage: Store leftovers covered in the refrigerator for up to 3-4 days. Freezing the finished dessert is not recommended.
