Jello is so much fun to work with! I’ve made so  many fun desserts with it. This Rainbow Poke Cake is right up there with my favorites! In honor of the up and coming St. Patrick’s Day, I added a little gold sprinkle to the whipped topping. I’m calling it “The End of the Rainbow” Jello Poke Cake! Here’s the how to:

You’ll Need:

  • 1 Package of White Cake Mix
  • Assorted Jellos – I used  red, orange, yellow, green, blue, & purple
  • About 6 cups of hot water
  • A squeeze bottle – Wilton makes some for decorating purposes. I’ve found them in the candy making aisle at Michael’s Craft Store
  • 1 16 oz. carton of heavy whipping cream
  • 2 T of powdered sugar
  • 1 box of instant vanilla pudding
  • 1 cup of milk
  • Gold Sprinkles – If you are going to Michael’s Craft Store  for the squeeze bottle – you can grab gold sprinkles there


  • Using a greased 9×13 baking dish, prepare, and bake  the white cake mix according to the back of the box
  • Let it cool for at least an hour
  • End of the Rainbow Jello Poke Cake
  • Poke several holes in the cake by pushing something round down into the cake
  • For a different look…You could vary the depth of each hole
  • To achieve a rainbow in each slice…I spaced mine very close together – about 1/2 inch apart
  • I used a sturdy straw to poke holes, but you can also use a wooden skewer or dowel

  • Prepare each jello separately
  • Starting with red. I poured half of the package into my squeeze bottle, and added enough hot water to dissolve the jello. I closed the cap on the bottle, and carefully – over the sink – swirled the liquid around until I thought the jello was dissolved
  • Then, I added more water from the tap to fill the bottle

  • I squeezed my red into the first holes along the narrow edge of the pan. I counted…starting at red…to the 7th hole down, and filled those with red jello, and did that again
  • With red as my starting point…I did the same procedure with orange immediately following red, then yellow, green, blue, and purple
  • You will most likely have some liquid left over
  • At this point, while I could still see the colors – I used masking tape to guide me in cutting the cake later. I taped a little piece on the baking pan lining up with the purple holes
  • I covered the cake and placed it in the refrigerator until the topping was finished

Whipped Topping (cloud):

  • Whip the whipping cream until soft peaks form
  • Add the powdered sugar, and whip in
  • Pour the instant vanilla into a separate bowl, and add the milk
  • Mix together, and let set up
  • Fold the vanilla pudding into the whipped cream
  • Spread on cake
  • Add gold sprinkles
  • End of the Rainbow Jello Poke Cake
  • Cover and refrigerate until serving
