Ingredients List
- 1 box white or yellow cake mix (plus ingredients required on the box)
- 1 package (3 oz) flavored Jello (any flavor of your choice)
- 1 cup boiling water
- 1 cup cold water
- 1 tub (8 oz) whipped topping, thawed
- Optional: fresh fruit, sprinkles, or edible flowers for garnish
Step-by-Step Instructions

Bake the Cake
Prepare the cake mix according to the package instructions and bake in a 9×13-inch pan. Allow to cool slightly for 10–15 minutes.
Poke the Cake
Using the handle of a wooden spoon or a large fork, poke holes evenly across the top of the warm cake, about 1–2 inches apart. The holes allow the Jello to seep in and flavor the cake from the inside.
Prepare the Jello
Dissolve the Jello in 1 cup boiling water, stirring until completely dissolved. Add 1 cup cold water and mix well. Allow to cool for 5 minutes so it’s warm but not hot.
Pour the Jello
Slowly pour the slightly cooled Jello over the cake, filling the holes and evenly covering the surface. Press gently to ensure the liquid seeps into all holes.
Chill and Set
Refrigerate the cake for at least 4 hours or until the Jello is fully set. This allows the flavors to meld and the cake to remain moist.
Finish with Topping
Spread whipped topping evenly over the set Jello cake. Garnish with fresh fruit, sprinkles, or edible flowers if desired. Slice and serve chilled.

FAQs
Can I use sugar-free Jello for this cake?
Yes, sugar-free Jello can be used, but adjust sweetness with additional whipped topping if desired.
Why did my Jello seep out unevenly?
The cake should be warm but not hot, and holes must be evenly spaced and deep enough for proper absorption.
Can I make this cake in advance?
Yes, prepare up to the chilling step the day before serving, then add whipped topping just before serving for optimal texture.
