Ingredients Method Notes

Ingredients
  

For the Cake
  • 1 box vanilla cake mix (plus ingredients called for on box)
  • 3 oz package vanilla or lemon jello
  • 1 cup boiling water
  • 1/2 cup cold water
For the Topping
  • 8 oz container whipped topping, thawed
  • 1/4 cup rainbow sprinkles (optional)

Method
 

  1. Bake the vanilla cake according to package directions in a 9x13 inch pan. Let it cool for exactly 15 minutes.
  2. Using the handle of a wooden spoon, poke holes about 1 inch apart across the entire cake surface. Make them deep enough to reach halfway through.
  3. Dissolve the jello powder in boiling water, stirring until completely clear - about 2 minutes. Add cold water and stir. The mixture should be warm but not steaming hot.
  4. Slowly pour the jello mixture over the cake, focusing on filling each hole. Use a spoon to gently coax jello into stubborn holes.
  5. Refrigerate for at least 3 hours until jello sets completely. Spread whipped topping evenly across the surface and add sprinkles if desired.

Notes

Perfect for making the night before family gatherings - the chilling time actually improves the flavors. Cake needs to cool for exactly 15 minutes before poking to prevent jello from completely soaking through while ensuring the cake doesn't crack. Requires 4 hours chill time total. Keep refrigerated for up to 5 days covered with plastic wrap or foil. This cake doesn't freeze well due to the jello and whipped topping. Serve chilled directly from the refrigerator for best texture and flavor.
