Ingredients

• 1 teaspoon vanilla extract
• 1 ¼ cups heavy whipping cream
• cooking spray
• 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
• 1 (1 ounce) package unflavored gelatin powder
• 1 (14.1 ounce) can sweetened condensed milk

Recipe Instructions

Step 1

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.

Step 2

Spray a 9-inch cake pan with cooking spray.

Step 3

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.

Step 4

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.

Step 5

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.

Step 6

Refrigerate until set, 4 hours to overnight.

Step 7

Run a knife along the sides of the cake pan and carefully invert cake onto a plate.
