In a mixing bowl, combine the lemon jello and gelatin. Add in 1 cup boiling water and stir until dissolved. I let my jello mixture sit for a few minutes to cool down before pouring the jello into my cups. Divide the among evenly among your cups.

Place the cups in the fridge to set.

Begin to prepare the creamy layer. In a mixing bowl, combine the sweetened condensed milk and 1 cup of boiling water. Stir to combine. In a separate smaller bowl, combine the 1/2 cup cold water and 2 gelatin packets, stir to mix. Allow the gelatin mixture bloom/set for 2-3 minutes.

Pour the gelatin mixture into the sweetened condensed milk mixture, stir to combine.

Once your jello is set, add in the creamy layer, making it as thick or thin as you’d like. You will have leftover cream mixture, which you’re suppose to, use that for the next creamy layer.

Once the cream layer is set, add the next jello layer, then repeat with another creamy layer, and such going forward. Note: If the sweetened condensed milk/gelatin mixture sets while you’re waiting for the jello to set, simply warm it up on the stove over low heat until it’s liquidy.

If desired top each jello cup with a dollop of cool whip and a lemon slice once all of the layers are set.
