1-First Step: Gather and prep your pan Start by getting out a nonstick Jello mold, bundt pan, or even a 9×13 pan if that is what you have on hand. Lightly coat the mold with cooking spray so the dessert releases more easily later. If you are using a bundt pan or ring mold, make sure every curve gets a light coating. This small step saves a lot of frustration when it is time to unmold.

2-Second Step: Dissolve the gelatin Pour the 6 ounce package of strawberry gelatin into a large bowl, then add 2 cups boiling water. Stir until the gelatin is fully dissolved. This part matters because any granules left behind can affect the final texture. Once the gelatin is smooth, whisk in 1 cup ice cold water. The cold water helps bring down the temperature quickly so the mold can start setting at the right pace.

3-Third Step: Cool the mixture Place the bowl in the refrigerator for about 15 minutes to cool the gelatin mixture. You do not want it fully set yet, just cool enough so it is no longer hot. That cooling time helps the sour cream blend in smoothly later. If the mixture is too warm, the creamy layer can thin out or set unevenly.

4-Fourth Step: Mix the cranberry sauce and sour cream In a medium bowl, whisk together the 15 ounce can of jellied cranberry sauce and 1 cup sour cream until smooth. The cranberry sauce gives the dessert its tangy fruit flavor, while the sour cream makes it rich and creamy. If you want a lighter version, plain Greek yogurt works too. For a fuller flavor, use full-fat sour cream.

5-Fifth Step: Combine the mixtures When the gelatin mixture has cooled, add the cranberry and sour cream mixture. Stir gently until everything looks evenly blended. Try not to overmix, because you want the texture to stay smooth and airy. This is the point where the dessert starts to take on that classic creamy strawberry Jello mold look.

6-Sixth Step: Pour into the mold Transfer the mixture into your prepared mold. Tap the pan lightly on the counter a couple of times to release any trapped air bubbles. If you are using a bundt pan, make sure the filling settles into all the grooves. If you are using a 9×13 pan, simply pour it in and smooth the top.

7-Seventh Step: Chill until firm Refrigerate the mold for at least 6 hours, but overnight is even better. The full chill time helps the strawberry Jello mold hold its shape when unmolded and sliced. Since this is a no-bake dessert, it is a great make-ahead option for busy holidays, potlucks, and family gatherings. For best results, leave it untouched while it sets.

8-Final Step: Unmold and serve To unmold, run a thin knife around the edges to loosen the dessert. Dip the mold briefly in hot water, but do not leave it in too long or the sides may start to melt. Place a serving plate on top, then invert the mold in one smooth motion. If it does not release right away, give it a gentle shake. Slice and serve with whipped cream if desired.
