Rainbow Fruit Tray with Marshmallows and Rolos: The Easiest Pot of Gold Dessert

If you need a show-stopping dessert that requires zero baking, almost no skill, and takes about ten minutes to put together, this rainbow fruit tray is the answer. Six colors of fresh fruit arc across a serving tray, fluffy marshmallow “clouds” tuck in below, and a pile of golden Rolo candies finishes the look like a literal pot of gold at the end of the rainbow.

It’s a guaranteed winner for St. Patrick’s Day, but I make it for Pride brunches, baby showers, birthday parties, Easter, and any spring or summer cookout where I want something colorful that disappears fast. Adults love it. Kids love it even more.

Here’s how to make it, plus every tip I’ve learned about keeping a fruit tray from going soggy before the party even starts.

Why You’ll Love This Rainbow Fruit Tray

• 10 minutes of prep. No cooking, no baking, no oven.
• Serves 10. Easy to scale up for a bigger crowd.
• Naturally gluten-free (skip the Rolos for dairy-free).
• A built-in conversation piece. The rainbow-and-pot-of-gold presentation does the heavy lifting.
• Make-ahead friendly. Prep the fruit the night before, assemble 15 minutes before serving.

The Best Fruit for a Rainbow Tray

The trick to a rainbow fruit platter is choosing fruit that holds its shape, doesn’t brown, and doesn’t release a ton of liquid onto your serving tray. Here’s the color breakdown I use for this recipe:

• Red: Strawberries (quartered, tops removed)
• Orange: Cantaloupe, chopped small
• Yellow: Pineapple, chopped small
• Green: Green grapes
• Blue: Blueberries
• Purple: Purple (red) grapes

Fruits I avoid for fruit trays

Skip these unless you have no choice — they’ll either brown, get mushy, or soak your tray:

• Apples and pears: Brown quickly once cut
• Bananas: Same problem, even faster
• Watermelon: Too juicy, makes everything soggy
• Plums: Tricky to slice into uniform pieces

Ingredients

This recipe makes one large rainbow fruit tray that serves about 10 people.

• 2 cups fresh strawberries, tops removed and quartered
• 1½ cups cantaloupe, chopped small
• 1½ cups pineapple, chopped small
• 1 cup green grapes
• 1 cup blueberries
• 1 cup purple grapes
• 2 cups miniature marshmallows
• 1 (10.6 oz) bag wrapped Rolo candies
• Store-bought fruit dip (optional)

Equipment You’ll Need

• A large round serving tray (a 14-inch round works perfectly)
• A small bowl or ramekin for the fruit dip
• A sharp chef’s knife and cutting board
• Paper towels (for drying cut fruit — this matters, I promise)

How to Make a Rainbow Fruit Tray with Marshmallows and Rolos

Step 1: Place the Fruit Dip

On a large round serving tray, set a small bowl of store-bought fruit dip in the center, positioned slightly toward the bottom edge of the tray. This will be the “base” of the rainbow.

Step 2: Add the Marshmallow Clouds and Gold

Pile the miniature marshmallows around the bottom of the fruit dip bowl — these are your clouds. Scatter the Rolo candies underneath and around the marshmallows for the pot of gold effect.

Step 3: Layer the Rainbow

Working outward in arcs above the marshmallow clouds, layer the fruit in rainbow order:

1. Purple grapes (closest to the clouds)
2. Blueberries
3. Green grapes
4. Pineapple
5. Cantaloupe
6. Strawberries (the outermost arc)

Place each fruit in a single layer first to lock in the rainbow shape. Once the rainbow is defined, go back and pile more fruit on top of each arc to fill out the board and give it that abundant, overflowing look.

Step 4: Serve Immediately

Rainbow fruit trays look (and taste) best within an hour of assembly. Serve right away.

Tips for the Perfect Rainbow Fruit Platter

Dry your cut fruit. This is the single biggest mistake people make. After chopping the cantaloupe and pineapple, spread the pieces on a paper-towel-lined plate and refrigerate for 30 minutes before assembling. The paper towel pulls out excess juice so your tray doesn’t turn into a puddle.

Cut everything roughly the same size. A rainbow fruit tray looks polished when the fruit pieces look intentional. Aim for bite-size — no piece bigger than a grape or a clementine wedge.

Build on a round tray for the classic rainbow shape. Rectangular trays work too, but a round tray gives you that perfect arc.

Assemble close to serving time. You can prep all the fruit the night before (wash, dry, cut, store in airtight containers with a paper towel inside). Just don’t actually arrange the tray until about 15 minutes before guests arrive.

When to Serve a Rainbow Fruit Tray

This is one of those recipes that works for almost every occasion:

• St. Patrick’s Day parties — the rainbow with clouds and gold is the St. Patty’s Day dessert
• Pride Month celebrations and brunches
• Easter brunch
• Mother’s Day brunch — pairs beautifully with a mimosa bar
• Birthday parties (especially rainbow-themed or unicorn parties)
• Baby showers and gender reveals
• Summer barbecues and pool parties
• Friendsgiving and Thanksgiving dessert tables

Rainbow Fruit Tray FAQ

Can I make a rainbow fruit tray ahead of time? Sort of. You can wash, dry, and cut all the fruit the night before — store each fruit separately in airtight containers with a paper towel inside to absorb moisture. But you should wait to actually assemble the tray until about 15 minutes before serving, otherwise the fruit will release juice and the rainbow will lose its crisp edges.

How much fruit do I need for a bigger crowd? This recipe serves 10. For 20 people, double everything. For 25 people, plan on roughly 15 cups of fruit total.

Do I need to cut the strawberries? Yes — a rainbow fruit tray looks best when all the pieces are about the same size. Quartering medium strawberries (or halving small ones) keeps the visual line of the rainbow clean.

Can I skip the Rolos and marshmallows? Absolutely. For a Pride or birthday-themed rainbow, skip the candy entirely. The marshmallows and Rolos are what make this version specifically read as a St. Patrick’s Day “pot of gold.”

What can I use instead of store-bought fruit dip? A few easy swaps: vanilla Greek yogurt, Cool Whip mixed with cream cheese, marshmallow fluff, or a simple 2-ingredient dip made from cream cheese and marshmallow fluff whipped together.

Is it cheaper to make a fruit tray than buy one? Almost always, yes — especially when you stick to fruit that’s in season.
