Pineapple Jello Poke Cake tastes like summer threw a party on a plate and invited everyone. Fluffy yellow cake made with pineapple juice instead of water (because we’re doing this RIGHT), poked full of holes, drenched in pineapple gelatin, topped with whipped topping, toasted coconut, and maraschino cherries. A whole tropical situation.
How to Poke Holes for Best Results
Wait ten minutes after baking — the cake should be warm but not scorching. Grab a FORK or wooden skewer, then poke holes ALL OVER the surface, about one inch apart.
Go deep! Plunge the tines right to the bottom of the cake. That’s where the jello pockets form. Don’t be shy — more holes = more flavor bursts. This is where the magic happens. Work quickly while the cake is still warm so the gelatin flows in. No timid poking allowed!
Make-Ahead & Storage Tips
ASSEMBLE IT THE NIGHT BEFORE This cake NEEDS time to chill and meld, so your fridge does half the work…. let it
- Cover tightly with plastic wrap, keeps 3-4 days refrigerated
- Hold the toasted coconut and cherries until RIGHT before serving (they turn soggy fast!)
- Cake base alone freezes well for up to 2 months, wrap in plastic first, then foil
- Thaw frozen cake overnight in the fridge before adding the whipped topping layer
Plan ahead, chill thoroughly, and you’ve got yourself a stress-free showstopper. (Your future self will absolutely thank you.)
How to Toast Coconut
Grab a DRY skillet (no oil needed!) and toss in coconut over medium heat. Stir CONSTANTLY because this stuff burns in SECONDS…. 3-5 minutes of nonstop stirring gets you golden.
Spread it on a plate IMMEDIATELY to halt cooking. Prefer the oven? 325°F on a baking sheet for 5-8 minutes, stirring halfway. Color lies, so taste-test first!

Ingredients
For the cake:
- 15 oz yellow cake mix
- 4 eggs (room temperature)
- 1/2 cup oil
- 1 cup pineapple juice (reserved from canned chunks)
For the syrup:
- 6.8 oz pineapple gelatin
- 1.5 cups boiling water
For the topping:
- 16 oz whipped topping
- 20 oz pineapple chunks (thoroughly drained)
- 3/4 cup toasted coconut
- 1 teaspoon vanilla extract
- 10-12 maraschino cherries
Step 1: Bake the Pineapple Infused Cake
- 15 oz yellow cake mix
- 4 eggs
- 1/2 cup oil
- 1 cup pineapple juice
Preheat your oven to 350°F (or follow box instructions).
In a large mixing bowl, combine the yellow cake mix, room temperature eggs, oil, and pineapple juice—this substitution of pineapple juice for water adds moisture and tropical flavor to the cake.
Mix until just combined and smooth, being careful not to overmix.
Pour the batter into a greased 9×13 inch baking dish and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.
I prefer using room temperature eggs because they incorporate more smoothly into the batter, creating a more tender crumb.
Step 2: Create the Liquid Channels
Remove the cake from the oven and let it cool in the pan for 10 minutes—this allows it to set slightly while still being warm enough to accept the liquid gelatin without crumbling.
Using a fork or wooden skewer, vigorously poke holes all over the entire surface of the cake, spacing them about 1 inch apart.
Don’t be shy; you want plenty of holes for the gelatin to soak in and create those signature pockets of flavor and texture.
Step 3: Infuse with Warm Gelatin
- 6.8 oz pineapple gelatin
- 1.5 cups boiling water
In a medium bowl, pour the 1.5 cups of boiling water over the pineapple gelatin powder and stir continuously for about 2 minutes until the gelatin is completely dissolved with no granules remaining.
Let the mixture cool for 3-5 minutes so it’s warm but not scalding hot.
Slowly pour the gelatin liquid over the entire surface of the cake, making sure it flows into all the poked holes.
Work carefully and pour in stages if needed to allow the liquid to fully absorb rather than pooling on top.
Step 4: Refrigerate Until Firm
Place the cake in the refrigerator and chill for at least 45 minutes until the gelatin is completely set and no longer jiggles when the pan is gently moved.
This is a critical step for proper texture—rushing it will result in a soggy topping layer.
Step 5: Whip up Pineapple Topping
- 16 oz whipped topping
- 1 teaspoon vanilla extract
- 20 oz pineapple chunks
In a large bowl, fold together the whipped topping, vanilla extract, and drained pineapple chunks until evenly combined.
I like to add the vanilla extract because it enhances the tropical flavors and adds subtle depth to the topping.
Gently fold rather than stir to keep the whipped topping light and airy.
Step 6: Layer and Garnish
- topping mixture from Step 5
- 3/4 cup toasted coconut
- 10-12 maraschino cherries
Spread the pineapple-whipped topping mixture evenly over the chilled cake, working from the center outward for a neat finish.
Sprinkle the toasted coconut generously over the top, then arrange the maraschino cherries in a decorative pattern across the surface.
Return the assembled cake to the refrigerator for 1-2 hours before serving to allow all layers to meld together and achieve the perfect chilled consistency.
