Ingredients
  

For the Cake
  • 1 box white cake mix Duncan Hines Signature White suggested
  • 1 cup whole milk to replace water for richness
  • 1/3 cup vegetable oil
  • 3 eggs room temperature
  • 1 teaspoon pure vanilla extract
For the Jello Layer
  • 3.3 oz strawberry gelatin
  • 1 cup boiling water
  • 1 cup cold water
  • 1/8 teaspoon fine sea salt
For Topping
  • 16 oz whipped topping thawed
  • red and pink heart sprinkles

Equipment

  • 9x13 inch baking pan
  • Large mixing bowl
  • Electric mixer or whisk
  • Medium bowl
  • Fork, toothpick, or wooden spoon
  • Spatula

Method
 

  1. Preheat your oven according to the temperature indicated on the cake mix package. In a large mixing bowl, add the cake mix, whole milk, vegetable oil, eggs, and vanilla extract. Using a whisk or electric mixer set to medium speed, blend everything together for approximately 2 minutes until you have a smooth, well-incorporated batter. Transfer the batter into a 9x13 inch baking pan and bake following the package instructions (generally 25-30 minutes), checking for doneness with a toothpick—it should come out clean or with only a few moist crumbs attached.
  2. Take the cake out of the oven and allow it to cool in the pan for 15-20 minutes, ensuring it sets slightly while staying warm enough for optimal jello absorption. Using a fork, toothpick, or wooden spoon handle, poke holes all over the cake surface, spacing them approximately 1 inch apart and creating a thorough, systematic pattern throughout to guarantee even jello distribution.
  3. In a medium-sized bowl, mix together the strawberry gelatin powder and fine sea salt. Add the boiling water and stir continuously for about 2 minutes until the gelatin granules dissolve completely and the mixture is smooth. Allow this to cool for roughly 5 minutes, then mix in the cold water. Gently and evenly pour the jello mixture over the entire poked cake surface, letting it naturally flow down into all the holes you created.
  4. Transfer the cake to the refrigerator and chill for 3-4 hours minimum, or ideally overnight. This extended chilling time allows the jello to fully set and penetrate deeply throughout the cake, developing those distinctive poke cake streaks and allowing the strawberry flavor to infuse the entire dessert.
  5. Once the cake is completely chilled and the jello has firmed up, spread the thawed whipped topping evenly over the top using a spatula or back of a spoon, creating decorative swirls and peaks as desired. Finish by sprinkling the red and pink heart sprinkles generously across the whipped topping for a festive Valentine's Day look. Serve immediately while cold.

Notes

The key to perfect jello penetration is timing—poke holes while the cake is slightly warm but set, not piping hot or completely cool. Stir the gelatin mixture for the full 2 minutes to ensure complete dissolution and prevent lumps. Don't skimp on creating a dense pattern of holes; this ensures even color distribution throughout. This cake can be prepared up to two days in advance and stored covered in the refrigerator. Add the whipped topping and sprinkles just before serving for the best presentation. Store leftovers tightly covered in the refrigerator for up to four days, but do not freeze as the texture will suffer. Serve cold for the best flavor and texture contrast.
