Ingredients
5 (3 ounce) packages sweetened gelatin mix (such as Jell-O®), 5 different colors
3 ½ cups boiling water, divided
3 ½ cups cold water, divided
cooking spray
1 (1 ounce) package unflavored gelatin powder
1 (14.1 ounce) can sweetened condensed milk
1 ¼ cups heavy whipping cream
1 teaspoon vanilla extract
Directions
Pour each gelatin mix into a separate bowl. Pour 1/2 cup boiling water into one bowl and stir until gelatin is completely dissolved, about 2 minutes; stir in 1/2 cup cold water. Repeat to dissolve remaining gelatin colors. Refrigerate all bowls until completely set, 4 hours to overnight.
Spray a 9-inch cake pan with cooking spray.
Remove gelatin from the refrigerator and slice each color into cubes. Transfer cubes to a bowl and gently toss together to mix colors randomly. Tip into the prepared pan.
Pour remaining 1 cup cold water into a bowl and sprinkle unflavored gelatin over top; let sit until dissolved, 2 to 3 minutes. Add remaining 1 cup boiling water and stir until gelatin is completely dissolved.
Pour condensed milk into a blender. Add cream, unflavored gelatin mixture, and vanilla; blend until well combined. Pour over gelatin cubes in the cake pan. Use a spatula to evenly distribute milk mixture.
Refrigerate until set, 4 hours to overnight.
Run a knife along the sides of the cake pan and carefully invert cake onto a plate.
Recipe Tip
You can use leaf gelatin if you don't have powdered gelatin. Use the number of leaves needed to set 4 1/2 cups of liquid. Depending on the type of leaf gelatin, you will need about 12 leaves. Follow the package instructions to dissolve gelatin leaves before adding to milk-cream mixture.
