Preheat oven to 350 degrees Fahrenheit 

Spray a Bundt Pan (15 cups) with Nonstick Spray

Follow the instructions on the box to prepare the Strawberry Cake. Pour batter into the bundt pan. Shake it to distribute the batter evenly

For flan: place the milk, eggs, condensed milk, vanilla, and cream cheese in a blender. Blend until creamy

Pour the flan mixture on top of the strawberry mixture. Use a circular motion to distribute the flan batter evenly. During the baking process, the layers interchange so the flan goes to the bottom and the strawberry cake rises to the top

Cover the bundt pan with aluminum foil

Place bundt pan inside a larger pan filled with 2 inches of boiling water. Bake for 50-60 minutes or until a toothpick inserted in the middle of the cake comes out clean

Remove from the oven and let it cool for 30 minutes on the counter before placing in the fridge to cool overnight

Unmold the cake onto a plate and place in the fridge while making the jello layer

Clean the bundt pan and lightly spray it with nonstick spray

For Jello layer, cook 2 cups of milk with the jello on medium heat while whisking. When the milk boils, keep whisking for 2-3 minutes or until the jello has completely dissolved

Strain into a bowl and add the remaining 2 cups and milk and stir. Let it cool slightly 

Flip back the cake back in the bundt pan. Carefully add a piping bag between the mold and the cake. Add the jello mixture in the piping bag until the cake starts floating in the jello. Leave some liquid jello for the top 

Place cake back in the fridge and top with remaining jello

Refrigerate for 2 hours or until jello has set

To unmold, use a hair dryer for a few seconds on the sides to loosen the jello

Enjoy!
