How to Make Unicorn Rainbow Jell-O Poke Cake Recipe
Step 1: Bake the Cake
Start by preparing the white cake mix exactly as instructed on the box—usually eggs, oil, and water blend to make the batter light and fluffy. Pour it into a 9×13 inch pan and bake until golden and springy to the touch. Cooling the cake fully is essential before moving on, so it can soak up all the delicious Jell-O without falling apart.
Step 2: Make the Jell-O Filling
While the cake cools, mix up each flavor of Jell-O separately. Dissolve one 3 oz box in a cup of boiling water, then stir in half a cup of cold water. Let the mixtures cool down to room temperature so they won’t melt the cake when poured.
Step 3: Poke the Cake
Using the back of a spoon or a skewer, gently poke holes all over the cooled cake. These little channels will allow the beautifully colored Jell-O mixtures to seep in and create the iconic rainbow poke cake pattern.
Step 4: Add the Jell-O
Pour each Jell-O flavor slowly and carefully over the cake, one at a time, starting with strawberry, then blue raspberry, and finishing with lemon. Try to spread the colors evenly to give the cake a stunning layered rainbow effect. Once poured, refrigerate the cake for at least two hours so the Jell-O can set and firm up beautifully.
Step 5: Prepare the Whipped Topping
In a mixing bowl, whip the heavy cream with powdered sugar until soft peaks form, then gently fold in the tub of whipped topping. This mixture creates a luscious, airy frosting that perfectly complements the fruity and refreshing cake layers.
Step 6: Frost the Cake
Once the Jell-O is set solid, spread the whipped topping evenly over the entire cake. The smooth, creamy topping offers a lovely contrast to the juicy, colorful cake beneath.
Step 7: Decorate the Cake
Sprinkle a generous amount of rainbow sprinkles across the cake’s surface for a playful touch. For the ultimate unicorn theme, add decorative toppers or edible glitter to add sparkle and whimsy that will delight everyone.
Step 8: Serve
Slice the cake into generous pieces and watch as your friends’ and family’s faces light up with joy at the vibrant, fruity rainbow surprise inside. This is a dessert that’s as fun to eat as it is to admire!
How to Serve Unicorn Rainbow Jell-O Poke Cake Recipe
Garnishes
To make your Unicorn Rainbow Jell-O Poke Cake Recipe extra special, consider garnishing with fresh berries or edible flowers for a pop of natural color. Adding a drizzle of fruit syrup or a sprinkling of crushed candy can elevate the texture and flavor even more.
Side Dishes
This joyful cake pairs wonderfully with light accompaniments such as a simple vanilla ice cream scoop or a fresh citrus sorbet. The cool, creamy sides balance the fruity, gelatin-infused sweetness beautifully, making each bite a refreshing treat.
Creative Ways to Present
Presentation is where you can really let your creativity shine. Serve the cake on a bright pastel platter, or add themed plates and unicorn party napkins for celebrations. For a whimsical touch, display it alongside colorful cupcakes or a pastel candy buffet to create a unified magical dessert table.
Make Ahead and Storage
Storing Leftovers
Once frosted and decorated, keep your leftover Unicorn Rainbow Jell-O Poke Cake Recipe covered tightly with plastic wrap or in an airtight container in the refrigerator. It will stay fresher for up to 4 days while preserving both the texture of the cake and the delicate whipped topping.
Freezing
Because of the Jell-O and whipped topping, freezing is not recommended for this poke cake. Freezing can change the texture and cause the Jell-O to weep or become watery upon thawing. It’s best enjoyed fresh and chilled.
Reheating
This cake is best served cold or at room temperature, so reheating is not advised. Simply take it out of the fridge about 15-20 minutes before serving to let flavors mellow and the cake become perfectly soft.
FAQs
Can I use homemade cake instead of a box mix for the Unicorn Rainbow Jell-O Poke Cake Recipe?
Absolutely! A homemade white or vanilla cake works wonderfully and allows you to control ingredients and sweetness, just make sure it’s fully cooled before poking and adding the Jell-O.
What if I want to use different Jell-O flavors?
Feel free to swap in your favorite Jell-O flavors to customize the rainbow colors or taste. Just keep the same quantity and method for each flavor to maintain the cake’s structural integrity and colorful impact.
Can I make this cake vegan or dairy-free?
You can! Use a vegan cake mix and substitute whipped topping with coconut whip or another plant-based option. Selecting vegan gelatin alternatives like agar powder will help you keep the jelly layers intact and delicious.
How long does it take for the Jell-O to set in the cake?
For best results, refrigerate the cake for at least 2 hours, although letting it chill longer won’t hurt—overnight is even better to ensure it’s completely set and juicy.
Can I make the Unicorn Rainbow Jell-O Poke Cake Recipe in a smaller pan?
Yes! A smaller pan will just result in a thicker cake layer, so you may need to adjust baking time slightly. Just keep an eye on it to make sure it stays moist and cooked through.

Instructions
- Bake the Cake: Prepare the white cake mix according to package instructions including the required eggs, oil, and water. Pour the batter into a 9×13 inch baking dish and bake the cake as directed. Once baked, allow the cake to cool completely to room temperature.
- Make the Jell-O Filling: While the cake is cooling, prepare each flavor of Jell-O separately. Dissolve each 3 oz box of Jell-O in 1 cup of boiling water, stirring well, then add ½ cup of cold water. Allow each mixture to cool to room temperature before use.
- Poke the Cake: Using the back of a spoon or a skewer, poke holes evenly all over the cooled cake surface to allow the Jell-O to soak in.

Start with strawberry, then blue raspberry, and finish with lemon to create a rainbow layering effect. Refrigerate the cake for at least 2 hours to let the Jell-O set and firm up inside the cake.
- Prepare the Whipped Topping: In a mixing bowl, beat the heavy whipping cream with the powdered sugar until soft peaks form. Gently fold in the tub of whipped topping to combine.

Notes
- Make sure the cake is completely cooled before poking and adding the Jell-O to prevent it from melting and becoming soggy.
- Use a fine skewer or the back end of a teaspoon for poking uniform holes without crumbling the cake.

- The cake must chill for at least 2 hours or until the Jell-O is fully set for the best texture.
- Use full-fat whipped topping and cream for optimal taste and stability in the frosting.
- Decorations can be customized based on party theme or personal preference.
