Holiday Striped Jello Cake
I stumbled upon this eye-catching striped dessert a while back, and now it's become my go-to for Christmas parties. Guests always gasp when they spot those cheerful red and green layers peeking through. What's great? It looks impressive but needs just basic stuff like boxed cake mix and flavored gelatin, so you can pull it off even with a jam-packed December schedule.
What Makes This Treat Special
Here's why this cake stands out as a holiday winner:
- The festive stripes inside give it that perfect Christmas vibe
- Every bite stays super juicy thanks to the gelatin infusion
- You can whip it up in a flash between holiday errands
- Prep it a day ahead and just finish the top when guests arrive
What You'll Need for Holiday Striped Jello Cake
- White Cake Mix: Works as your neutral foundation to showcase the bright colors and keeps preparation simple.
- Lime Jell-O: Delivers those stunning green stripes that make everyone think of Christmas trees.
- Cherry Jell-O: Creates the brilliant red pattern that screams holiday cheer.
- Whipped Topping: Adds that snowy, fluffy layer on top that everyone loves.
- Holiday Sprinkles: Bring that final touch of Christmas sparkle to your creation.
- Boiling Water: Needed to melt your gelatin packs for perfect pouring.
- Cold Water: Helps bring the temperature down so your gelatin sets just right.
Simple Steps to Create Your Cake
- Bake Your Foundation
- Follow your box mix directions and bake in a greased 9x13 dish. Let it sit out for around 20 minutes after baking—you want it slightly warm but not steaming hot.
- Prepare Your Gelatin
- While waiting on your cake, get both gelatin flavors ready. Pour hot water into each one and stir until completely smooth. Add your cold water next, then let them cool a bit without getting too thick.
- Create Your Cake Channels
- Here comes the fun! Grab a drinking straw or wooden spoon handle and poke holes all across your cake. Keep them about an inch apart, going deep but not touching the bottom. More holes means more flavor throughout.
- Add Your Color Magic
- Carefully pour your prepared gelatin—red on one side, green on the other. Watch as the colors sink into your cake. If you see puddles forming, just guide the liquid toward nearby holes.
- Chill Thoroughly
- Wrap with plastic and pop in the fridge. Wait at least 6 hours, though leaving it overnight works even better. This gives everything time to soak in and set up properly.
- Add the Finishing Touches
- Right before you plan to serve, spread your whipped topping across the entire surface. Scatter sprinkles on top however you'd like. Let your creative side take over—this part gets all the attention.
Helpful Hints
A white cake base really makes those holiday colors pop
- Try different gelatin flavors if you want to experiment
- A longer chill time gives you cleaner slices
- Add the top layer and decorations just before serving for best looks

Keeping It Fresh
This cake needs to stay in the fridge, covered well, and it'll remain tasty for up to 3 days. Planning way ahead? Don't add the topping yet—just wrap the cake tightly and freeze for up to a month. Thaw in your fridge overnight before adding the final toppings.
A Show-Stopping Dessert
Whenever this cake shows up at Christmas gatherings, it vanishes fast. Something about those bright, colorful layers under that fluffy white top just brings joy to everyone. Pair it with some warm cocoa or a festive punch and watch as it becomes the star of your holiday spread!
