4-ingredient PB&J Clusters

These 4-ingredient PB&J Clusters are an easy and healthy snack idea using just 4 ingredients: strawberries, raspberries and peanut butter. Such an easy tasty snack to satisfy your sweet tooth without the sugar.

You know those recipes that you kind of throw together once, not really expecting much—and then suddenly your entire household is obsessed and begging for you to make it again before you even finish cleaning the kitchen?

Yeah. That’s exactly what happened here with these Frozen Berry Peanut Butter Clusters.

These clusters are the snack of the summer. Like, truly. They’re cold and refreshing, loaded with juicy fresh strawberries and raspberries, and then drizzled with creamy peanut butter that turns into this soft, fudgy magic shell once frozen. Oh—and they’re made with only 4 ingredients (hi, mom win), come together in like 10 minutes, and are the kind of thing I feel so good about feeding my kids and grabbing for myself, too.

We’re talking no added sugar, packed with antioxidants and fiber, naturally sweet from the berries, and that little boost of protein and healthy fat thanks to the PB + chia seeds. Total snack plate perfection.

Let’s get into it!

What are Frozen Berry Peanut Butter Clusters?

These clusters are basically like little frozen fruit cookies, but make it wholesome. They’re super simple: you mix together finely chopped strawberries and mashed raspberries, stir in some chia seeds for a little fiber and texture (plus they help the mixture gel slightly), scoop them into little mounds, drizzle with peanut butter, then freeze.

You end up with this magical sweet-tart, creamy-dreamy, chewy-soft frozen treat that kind of feels like a PB&J turned into a popsicle. But it’s 100x easier and doesn’t leave you or your kids covered in melted goo.

They’re totally no-bake, no added sweeteners, gluten-free, dairy-free, vegan-friendly if that matters to you—and they store so well in the freezer. Like the kind of snack you make once and have stashed away all week.

How to Make Frozen Berry Peanut Butter Clusters

You don’t need anything fancy here—no blender, no mixer, not even a baking sheet. Just a bowl, a fork, and a cookie scoop (or spoon). Here’s what to do:

1. Prep the fruit.
Wash your berries, then finely chop the strawberries and mash the raspberries with a fork. You want some texture in the raspberries but mostly mashed.

2. Mix together.
Add the strawberries, raspberries, and chia seeds to a bowl and mix well. The chia seeds help the mixture thicken slightly as they sit for a few minutes, so don’t skip them!

3. Scoop and shape.
Using a cookie scoop or large spoon, form clusters with about 2-3 tablespoons of the mixture each. Drop them onto a parchment-lined plate or tray that will fit in your freezer.

4. Drizzle the PB.
Gently warm the peanut butter if needed (a few seconds in the microwave) so it’s drippy. Drizzle it over the top of each cluster.

5. Freeze.
Pop the plate or tray into your freezer and let the clusters freeze for about 1-2 hours, or until firm.

6. Store + snack.
Once frozen, transfer them to a freezer-safe container or bag. Enjoy straight from the freezer for the best texture.

Why We’re Obsessed With These

Okay, here’s the thing—these frozen berry peanut butter clusters are:

• Naturally sweet and so satisfying
  The fruit brings all the natural sugars and flavor you need. No honey, no syrup, no added anything—just pure, juicy berry goodness.

• Texturally perfect
  The strawberries give a little crunch, the raspberries melt in your mouth, the chia seeds add some chew, and the peanut butter drizzle brings this soft, creamy contrast once frozen. So good.

• Kid-approved and mom-approved
  My kids are obsessed with these. And I love that they’re full of real food ingredients I always have on hand. Plus, no mess while they eat them outside on a hot day = huge win.

• Freezer-friendly and make-ahead
  Make a double batch and stash them for those “I need something now” snack moments.

Swaps, Add-Ins + Tips:

Here are some fun ways to play around with the recipe or make it your own!

Want a different nut butter?
Go for it! Almond butter, sunflower seed butter, cashew butter—whatever your fam loves. Just make sure it’s the creamy, drippy kind so it drizzles well.

Only have frozen berries?
You can absolutely thaw and use frozen berries in a pinch. Just make sure you strain off excess liquid so the clusters hold together and aren’t too wet.

Want it a little sweeter?
If your berries aren’t super sweet, stir in a drizzle of maple syrup or honey to the fruit mixture. But usually, fresh summer berries have all the sweetness you need.

Add mini chocolate chips.
Need I say more? Stir a tablespoon or two of dairy-free mini chips into the fruit mixture before freezing for a chocolatey vibe.

Use them as smoothie toppers.
These clusters are amazing crumbled over a smoothie bowl for texture and flavor. Kind of like fruity granola meets frozen snack.

How to Store Frozen Clusters

Once the clusters are fully frozen, pop them into a sealed bag or container and keep them in the freezer. They’ll last up to 1-2 months—but I highly doubt they’ll make it that long.

I usually double the recipe and keep them in a Stasher bag so the kids can grab them after camp, on hot afternoons, or even for dessert.

If they sit out for too long they’ll soften, so just keep that in mind. We eat them straight from the freezer!

The Backstory Behind This Recipe

Honestly, this recipe was born out of one of those “it’s 4pm and everyone is hangry and we need something now” kind of moments.

I had a ton of fresh berries in the fridge, a half-empty jar of peanut butter on the counter, and a wild toddler asking for a snack every 90 seconds. So we threw some things in a bowl, scooped them into little piles, and I was this close to just eating it as-is—but decided to freeze them to see what happened.

And boom. A new staple was born.

They’ve become part of our weekly routine now, especially during the summer when berries are overflowing at the farmers market. We’ll make a batch on Sunday, freeze them, and they disappear by mid-week.

Why You’ll Love This

Let’s be honest—summer is chaos in the best and most exhausting way. Camps, parks, pool days, road trips, playdates, and so many snack requests.

These frozen clusters are such an easy thing to keep in your back pocket when life gets busy. They’re:

• Easy to make with your kids (hello, 3-ingredient recipe)

• Mess-free (no sticky hands or crumbs all over the couch)

• Perfect for on-the-go or poolside snacking

Plus, they’re just really fun. They feel like a treat, but you know they’re made with real ingredients that fuel your little ones (and yourself) in the best way.

Whether you’re a parent looking for a better snack for your kids, someone who needs a healthy sweet treat in the freezer for afternoon cravings, or you’re just obsessed with strawberries and peanut butter (same), these frozen berry peanut butter clusters are going to become your new go-to.

Make a batch, keep them stocked, and enjoy the easiest, healthiest treat of the summer.
