Ingredients You’ll Need

Gather your squad. This is the dream team that’s going to make magic happen. Pro-tip: if you can, let the canned pineapple and Cool Whip hang out on the counter for about 15-20 minutes before you start. It just makes everything easier to mix.

1 can (20 oz) Crushed Pineapple in 100% Juice: Do not drain! The juice is the secret flavor agent. We’re using the whole can, juice and all.
1 box (3.4 oz) Instant Vanilla Pudding Mix: This is the wizard that will transform our ingredients from soupy to superb. Instant is key here, cook-and-serve will not work (trust me, we don’t have time for that).
1 tub (8 oz) Cool Whip, thawed: The fluffy cloud base. Make sure it’s thawed in the fridge, or you’ll be trying to mix a rock.
2 cups Mini Marshmallows: For little pockets of chewy, sweet goodness. The mini ones distribute perfectly.
1 cup Sweetened Shredded Coconut: Optional, but highly recommended for that tropical vacation vibe.
Maraschino Cherries & Toasted Coconut for garnish: Because we eat with our eyes first, and it makes it look fancy.

Step-by-Step Instructions

The Big Mix. In a large, glorious bowl, dump in the entire can of crushed pineapple WITH its juice. Sprinkle the entire box of instant vanilla pudding mix right on top. Immediately start whisking it all together. Watch the wizardry happen as it thickens up almost instantly.
Fold in the Fluff. Grab a spatula and gently fold in the thawed Cool Whip. Be gentle! We’re not mixing concrete, we’re coaxing a cloud. Fold until no white streaks remain.
Add the Fun Stuff. Now, fold in your mini marshmallows and shredded coconut (if you’re using it). Make sure everything is evenly distributed.
The Patience Test. Cover the bowl with plastic wrap and pop it in the fridge for at least 2 hours. I know, waiting is the hardest part. This chilling time is non-negotiable—it allows the flavors to get to know each other and the marshmallows to get perfectly soft.
Serve & Impress. Scoop your glorious fluff into bowls, top with a cherry and a sprinkle of toasted coconut, and take a bow. You’ve done it.

Common Mistakes to Avoid

Draining the Pineapple: I see you, overachiever. Stop. The juice is essential for reacting with the pudding mix. If you drain it, you’ll have a sad, thick paste. Don’t do it.
Using un-thawed Cool Whip: If your Cool Whip is still frozen, you’ll end up with lumpy fluff. And nobody wants that. Plan ahead! Thaw it in the fridge overnight or for a few hours.
Vigorous Stirring: Once the Cool Whip is in, switch from a whisk to a spatula and fold. Whipping it will deflate all the air and you’ll lose the fluff in pineapple fluff.
Skipping the Chill Time: I get it, you’re excited. But serving it immediately is a soupy mistake. The marshmallows need time to soften and the whole thing needs to set. Trust the process.

Alternatives & Substitutions

This recipe is wonderfully forgiving. Here’s how to make it your own:

Dairy-Free? Use a dairy-free whipped topping (like So Delicious CocoWhip) and ensure your pudding mix is a brand that’s dairy-free (Jell-O Brand is not, but many store brands are).
Not a Coconut Fan? Just leave it out! The recipe is still fantastic without it.
Pudding Flavor Swap: Butterscotch pudding is a legendary swap for a totally different (and delicious) flavor profile. Lemon would also be fantastic for a brighter, zingier fluff.
Add-Ins: Feel free to throw in a handful of chopped nuts (pecans are awesome) or even some mandarin orange segments for a dreamsicle-type situation. Go wild!

FAQ

Can I use fresh pineapple instead of canned?

Technically, you could, but I wouldn’t recommend it. Fresh pineapple contains an enzyme called bromelain that breaks down protein. It will prevent your pudding from setting properly and turn your fluffy cloud into a sad, runny puddle. Canned pineapple is cooked during the canning process, which deactivates the enzyme, making it the safe choice here.

How long does pineapple fluff last in the fridge?

It’s best enjoyed within 2-3 days. After that, the marshmallows can start to get a little too soft and it might weep a little liquid. But let’s be real, it’s never going to last that long.

Can I make this ahead of time?

Absolutely! It’s the perfect make-ahead dessert. In fact, making it the night before is brilliant because it gives the flavors even more time to mingle and party.

My fluff is runny! What did I do wrong?

Did you drain the pineapple? Or maybe you didn’t use instant pudding mix? Those are the usual suspects. If it’s a little soft, just give it more time in the fridge to firm up.

Can I use whipped cream instead of Cool Whip?

You can, but it won’t be quite the same. Cool Whip is stabilized, so it holds its shape for days in the fridge. Real whipped cream will deflate and get watery much faster. If you’re serving it immediately, go for it! Whip up 2 cups of heavy cream with a little sugar until you get stiff peaks, then fold it in.

Is there a way to make this lower in sugar?

You can try using sugar-free instant pudding mix and light Cool Whip. It will change the texture and flavor slightly, but it’ll still be tasty! The pineapple will still contribute natural sugars, though.

Now go forth and make fluff! Your future self, happily eating a bowl of this tropical goodness, will thank you.
