Dive into island vibes with a Hawaiian poke cake that mixes pineapple, coconut, and silky banana pudding. It's the kind of sweet treat that just screams 'I'm on vacation.' I whipped this up for a sunny summertime potluck and, honestly, it disappeared in no time.
The first time I baked this was for my kid's luau-themed birthday bash. Now, it's a staple request at family get-togethers. There's just something about that soft cake and ultra creamy center that makes everyone go wild for seconds.
Irresistible Ingredients
- Vanilla cake mix: Starts you off quick and lets those island flavors shine
- Crushed pineapple: Packs in natural tang and a seaside sweetness
- Banana cream pudding: Creamy with a little tropical oomph—so good with pineapple
- Sour cream: Makes the boxed cake extra moist and gives it a homemade feel
- Whipped topping: Adds a cloud-light finish to balance the dense base
- Optional coconut flakes: Crank up the tropical crunch if you want
Simple How-To Steps
- Start Chilling:
- Once it's at room temp, loosely lay plastic wrap on top then stick it in the fridge for at least 4 hours (overnight is best). The cake soaks up the pudding while it chills, so the flavors really meld together.
- Layer It Up:
- Spread whatever pudding is left across the cake—get it nice and even. Drain your extra pineapple and sprinkle it over the top for juicy bursts in every forkful.
- Make the Holes:
- Grab a wooden spoon's handle and poke big holes all over the warm cake, spaced about an inch apart. The cake should be just warm, not hot, so it doesn't get too mushy. Make sure you get those holes deep for maximum filling.
- Get the Batter Ready:
- Mix cake mix, eggs, milk, butter (melted), and sour cream in a bowl. Skip the box directions! Beat together for a couple of minutes so your batter gets airy and fluffy. That's the trick for a super tender cake.
- Bake the Cake Layer:
- Pour everything into a sprayed 9x13 dish and cook at 350°F for about 25–30 minutes. Once it springs back to the touch and passes the toothpick test, pull it out to cool for just a few minutes.
- Mix Up the Filling:
- Whisk together the banana pudding mix, cold milk, and a cup of crushed pineapple (with juice). It'll thicken up fast, so don't hang around—work quickly!
- Add the Whipped Topping:
- Smooth whipped topping over everything. Make some fun swirls. This layer makes it feel extra fancy but also balances out all that sweetness underneath.
- Fill Every Pocket:
- Pour the banana-pineapple mix into each hole, using a spatula to nudge it in deep. You want every bite to be loaded with filling.

What makes this treat next-level for me is the combo of super soft cake soaked with pudding and the pineapple chunks that add little bursts of texture. My grandma, who grew up on the islands, says it feels just like the desserts she'd eat at casual gatherings back home.
Switch Things Up
You can totally make this your own. Swap out banana pudding for coconut cream, or tuck some toasted coconut between the pineapple and topping. If you wanna make it wild, fold in mini marshmallows to the whipped topping right before spreading it on.
Serving and Storing
It keeps nicely in the fridge for up to five days, though ours never actually makes it that long. Keep it covered so it doesn't taste like last night's leftovers. Heads up, though—freezing this isn't great since pudding and topping don't hold up well once thawed.
Tasty Pairings
Enjoy this with a cup of Kona coffee or a scoop of vanilla ice cream if you're feeling fancy. Wanna keep the island theme? Serve after some Hawaiian grilled chicken and coconut rice. This sweet is filling without being too heavy, so it's awesome after a big meal.

Common Questions
- → How can I keep the pudding filling super creamy?
Mix your banana cream pudding mix with cold milk and whisk it really well until the texture is smooth. No lumps means your filling turns out creamy every time.
- → Is it okay to swap in fresh pineapple for the canned kind?
Go ahead and use fresh pineapple if you want. Smash it up finely, and pour in the juice with it to get the same feel and taste as canned.
- → What's a good way to get the whipped topping just right?
Scoop out the whipped topping with a spatula and gently smooth it over the top. Try not to press too hard or mix it into the layers underneath.
- → Can this dessert be made in advance?
Definitely! Put it together a day before, stash it in your fridge, and you'll find it slices easier and tastes even better after sitting overnight.
- → What fun toppings go well with this treat?
Toasted coconut flakes and chunks of fresh pineapple look and taste great. Want a little extra? A quick swirl of caramel on top is awesome too.
