What You’ll Need

(Exact quantities are listed in the recipe card below.)

Start with a base of crushed graham crackers and melted butter. That’s your sturdy-but-delicious foundation. The filling is a layered mix of rainbow sherbet, whipped topping, mini marshmallows, and a sprinkle of love (okay, actual rainbow sprinkles).

You can mix in white chocolate chips for a little extra sweetness and creamy texture, or leave them out if you want to keep things light and bright.

How to Make Easy No-Bake Rainbow Sherbet Bars

Step 1: Prep the Crust

In a medium bowl, mix the crushed graham crackers with the melted butter until it resembles wet sand. Press the mixture firmly into the bottom of a parchment-lined 8×8 pan. Place in the freezer for 10 minutes to set.

Step 2: Make the Filling

Let your rainbow sherbet soften just a bit don’t melt it completely. In a large bowl, gently fold together the sherbet with the whipped topping, mini marshmallows, and white chocolate chips if using. Work fast so the sherbet doesn’t get too runny.

Step 3: Assemble & Freeze

Spread the filling evenly over the chilled graham cracker crust. Smooth the top and decorate with a generous handful of rainbow sprinkles. Cover and place in the freezer for at least 4 hours, or until firm.

Step 4: Slice & Serve

Once set, use a warm knife to slice into bars. Serve immediately and watch everyone smile. These are sweet, cool, and just the right amount of nostalgic like a bite-sized rainbow sherbet cake that melts in your mouth.

Pro Tips for the Best Sherbet Bars

Use a mix of sherbet flavors (lime, raspberry, orange) for a real rainbow effect.
Want it more like a rainbow cookie cheesecake? Add a thin layer of whipped cream cheese before the sherbet layer.
Don’t skip the parchment paper it makes lifting and slicing way easier.
Let bars sit for a minute or two at room temp before slicing to prevent crumbling.
Leftovers? Store in an airtight container in the freezer (they’ll keep for up to 1 week).

These bars are made to impress at parties, picnics, or just an ordinary Tuesday that needs a little color.

Serving Tips:

A Sweet Story Behind the Swirl

These were born on a hot summer day when I was trying to make something fun that didn’t involve baking or turning the kitchen into a sauna. My daughter saw the sherbet in the freezer and said, “Can we turn this into bars?” The rest is sweet, pastel-colored history.

Frequently Asked Questions

Can I use ice cream instead of sherbet?

Yes! Ice cream works, though it’ll be a bit creamier and less fruity. For the best rainbow cheesecake vibe, use colorful sherbet.

How do I get clean slices?

Run a knife under hot water and wipe it between cuts for sharp, neat edges.

Can I make this ahead?

Definitely. These are a perfect make-ahead treat. Just keep them frozen until ready to serve.

What can I use instead of graham crackers?

Crushed vanilla wafers, shortbread cookies, or even rainbow cookies if you want a full rainbow cookie cheesecake effect.

Do I have to use mini marshmallows?

Nope but they add a fun texture. You could sub in more white chocolate chips or even chopped candy.

Is whipped topping necessary?

It gives that fluffy texture and helps the filling hold together. Homemade whipped cream can work too, just make sure it’s stable.

Can I use a different pan size?

Sure! 8×8 gives thicker bars, while 9×13 will give thinner ones just adjust freezing time accordingly.

What’s the best sherbet flavor combo?

Lime, raspberry, and orange is a classic. But go wild rainbow is the goal here!
