If you read MBA on a regular basis, you know that we’re kind of obsessed with fluff desserts around here. From Cranberry Fluff and Orange Fluff to Ambrosia, creamy, dreamy desserts are where it’s at – especially during the warmer months.

Since making Orange Fluff last month, I’ve been all about experimenting with different flavor combinations and this Pineapple Fluff is most definitely our new favorite.

Pineapple Fluff is made with pineapple Jello mix and crushed pineapple. So easy and amazing!

With just a handful of simple ingredients like pineapple Jell-o mix, crushed pineapples, cottage cheese, whipped topping and Campfire® Mini Marshmallows, you’ll be whipping up this delicious pineapple dessert all summer long.

When I posted the Orange Fluff recipe on Facebook last month, some people were a little iffy about the cottage cheese used in the recipe. But I’m here to tell you that it imparts an amazing texture to this dessert, and also prevents it from being too sweet. Please don’t skip it or swap it!

Pineapple Fluff tastes like a bite of joyful sunshine. The brightness and creamy texture will bring smiles to everyone!

My mom always pureed the cottage cheese when she made fluff desserts. Pureeing the cottage cheese makes it pretty much undetectable and creates a thick, creamy texture that makes the fluff – well, fluffy.

My dad absolutely loathes cottage cheese, and he had two huge servings of this after dinner. In fact, he still doesn’t know he was raving about a dessert that contained cottage cheese.

Pineapple Fluff has just the right amount of pineapple sweetness. Combined with the marshmallows, you have a treat that's unforgettable!

Make sure you use the right marshmallows for this recipe. While I love Campfire® Marshmallows’ mini fruit marshmallows, for this recipe, I knew I had to stick with the classic mini marshmallows. Why? To let all that pineapple flavor shine through! That tropical treat really makes this version of fluff special, and pairing it with creamy, sweet marshmallows only brings out the tangy flavor.

I’ve partnered with Emily from Jelly Toast and Campfire® Marshmallows to create recipes to share with you throughout the entire year. If you’re a marshmallow lover, you’ll definitely want to stay tuned for loads of ooey-gooey goodness!

We even created a Marshmallow Madness Pinterest board where we’ve pinning loads of delicious marshmallow recipes that are perfect for any occasion. Like these S’mores Cookie Cups and No Bake S’mores Cheesecake.

    Hi! Love this recipe, I just have one question.
    I live in the Netherlands, and have never seen frozen whipped topping. Could I just use fresh whipped cream?


    • Jamie — May 3, 2016 at 12:06 pm

      Hi, Tamar! I think you could substitute sweetened whipped cream, but the texture will probably be different. I hope you like it!

    I want to swan dive into this delicious dessert! Growing up my mom always had cottage cheese on hand so I love in just about ANYTHING! (I’m serious! In lasagna it’s great, it’s fluff dessert it’s great and plain it’s great!) BUT I love marshmallow probably a little more than cottage cheese. I love campfire marshmallows because they are so squishy and soft – I know they worked great in this fluff!

      Thank you, Brandy! xxoo

    This looks amazing! I made myself pineapple overnight oatmeal, but now I wish I had saved the pineapple for this. Haha!!


    • Jamie — May 5, 2016 at 2:23 pm

      Pineapple oatmeal sounds amazing, Kloe!

  10. I have a great aunt that back in the day was KNOWN for her jello molds and fluff desserts and she always used cottage cheese too. I don’t get the cottage cheese hate out there! This fluff looks rockin’.

    How long does this stay good in the fridge ?


    • Jamie — February 21, 2017 at 8:16 am

      Hi, Shan! I usually serve this the same day I make it, so I can’t honestly say. Maybe a day or two? I hope you enjoy it!
