Ingredients:

  • 1 box (15.25 oz) white cake mix
  • 3 large eggs
  • 1/2 cup vegetable oil
  • 1 cup water
  • 1 package (3 oz) Jell-O gelatin powder
  • 1 cup boiling water
  • 1/2 cup cold water
  • 1 tub (8 oz) Cool Whip, thawed
  • 3 tbsp sweetened condensed milk

Instructions:

  1. Preheat oven to 350°F (175°C). Combine cake mix, eggs, oil, and water in a bowl. Beat on medium speed for 2 minutes until smooth and pale.
  2. Pour batter into a greased 9x13 inch baking pan and bake for 30–40 minutes until the edges pull away and a toothpick comes out clean.
  3. Allow cake to cool for 15–20 minutes. Using a wooden spoon handle, poke holes across the entire surface, spaced 1 inch apart, pushing nearly to the bottom.
  4. Dissolve gelatin powder in 1 cup of boiling water, stirring for 2 minutes. Stir in 1/2 cup of cold water.
  5. Slowly pour the liquid gelatin over the cake, ensuring every hole is filled.
  6. Refrigerate the cake uncovered for at least 2 hours until the gelatin is set.
  7. Whisk sweetened condensed milk into the thawed Cool Whip, then spread evenly across the top of the cake.
  8. Return to the fridge for another 2 hours before slicing and serving.
