Tools of the Trade

Colorful Jello Poke Cake: From Prep to Plate

Step 1: Bake the Cake
Preheat your oven according to the cake mix instructions. Prepare your 9-inch cake pans with cooking spray or parchment paper. Mix the cake batter as directed on the package, pour it into the prepared pans, and bake until golden brown and a toothpick inserted comes out clean. Let the cakes cool completely on a wire rack.
Step 2: Prepare the Jell-O
In a mixing bowl, dissolve the two packages of Jell-O in 2 cups of boiling water. Stir well until completely dissolved. Allow the mixture to cool for a few minutes.
Step 3: Poke the Holes
Once the cake layers have cooled, place them back in the cake pans. Using a fork or skewer, poke holes all over the tops of the cakes, ensuring they are evenly spaced.
Step 4: Pour the Jell-O
Carefully pour the cooled Jell-O mixture over the cakes, making sure it seeps into the holes. Cover the cakes with plastic wrap and refrigerate for at least 4 hours, or overnight for the best results.
Step 5: Frost with Cool Whip
After the cakes have set, remove them from the refrigerator and gently lift them from the pans. Place one layer on a serving platter and spread a generous amount of Cool Whip on top. Place the second layer on top and frost the top and sides of the cake with the remaining Cool Whip.
Step 6: Decorate and Serve
Feel free to get creative with decorations! You can add fresh fruits, sprinkles, or additional Jell-O cut into small pieces on top. Slice, serve, and enjoy the colorful explosion of flavors with your guests!

Troubleshooting Q&A
What if my Jell-O didn’t set properly?
Ensure you’ve used the correct ratio of boiling water to Jell-O and allowed it enough time to cool before pouring it over the cake. If you encounter issues, it may help to refrigerate it longer to allow the Jell-O to firm up.
Can I use different flavors of Jell-O?
Absolutely! Feel free to mix and match your favorite flavors or use seasonal colors for holidays. The options are endless, making it a fun way to personalize the cake for your event.
How do I store leftovers?
Store any leftover Colorful Jello Poke Cake in an airtight container in the refrigerator. It should be good for about 3-4 days. Just be mindful that the Cool Whip may start to separate slightly over time.
Can I freeze this cake?
While it’s not recommended to freeze the entire assembled cake due to the Cool Whip, you can freeze the individual cake layers before adding the Jell-O and frosting. Once frozen, wrap them tightly in plastic wrap and aluminum foil for up to 2 months. Thaw before assembling and adding the Jell-O.
