Ingredients You’ll Need

5 cups Fruity Pebbles cereal: Fruity Pebbles cereal provides the crunchy, colorful base and light fruity flavor that defines these bars.
1 cup mini marshmallows: Mini marshmallows add extra chew and help bind the cereal when mixed with the melted marshmallow base.
4 tablespoons unsalted butter: Unsalted butter melts into the marshmallows to create a glossy, slightly rich coating that keeps the bars tender.
10 ounce bag large or mini marshmallows: The bag of large or mini marshmallows is the primary binding ingredient—melted they create the sticky matrix that holds the cereal together.
1/2 cup white chocolate chips, optional: White chocolate chips are optional and used only for a sweet, decorative drizzle that adds visual contrast and extra sweetness.

How to Make Fruity Pebble Treats

Line an 8×8-inch square baking pan with parchment paper or aluminum foil and grease it generously with cooking spray or butter so the bars release cleanly.
In a large bowl, stir together the 5 cups Fruity Pebbles cereal and 1 cup mini marshmallows; set this dry mixture aside while you melt the butter and marshmallows.
In a large, heavy-bottomed pot, melt 4 tablespoons unsalted butter over low heat. Add the 10 ounce bag of large or mini marshmallows and stir constantly until fully melted and smooth, then remove from heat immediately.
Pour the bowl with the cereal and mini marshmallows into the pot with the melted marshmallows and butter. Stir thoroughly until every piece of cereal is evenly coated.
Transfer the sticky mixture to the prepared baking dish and press down tightly until the top is level—press firmly with a greased spatula or use a buttered flat-bottomed cup to compress the bars.
Let the pan set at room temperature or refrigerate for 1 1/2 hours to firm. If using white chocolate, melt 1/2 cup white chocolate chips at 50% power in 15–30 second intervals in a microwave-safe bowl, stirring between intervals, or melt gently over a double boiler.
Drizzle the melted white chocolate over the bars with a spoon, then allow the drizzle to firm for about 20 minutes, or until the white chocolate has set, before cutting into bars.

Get Chewy, Not Soggy

The key to chewy Fruity Pebble bars is a tight press and controlled melting. Melt the marshmallows over low heat and work quickly to coat the cereal so the marshmallow sets before the cereal softens.

If you need firmer bars for cleaner slicing, refrigerate the pan for 1 1/2 hours before cutting.

Use low heat when melting to keep the marshmallows glossy and smooth.
Mix the cereal and the 1 cup mini marshmallows dry first so the extra marshmallows distribute evenly.
Press the mixture firmly in an 8×8-inch pan to expel air and create dense bars.

White Chocolate Drizzle Tips

White chocolate can seize or scorch easily, so melt it gently in short microwave bursts at 50% power or over a double boiler. Stir between intervals until smooth.

If the drizzle thickens before you finish, stir in a few drops of neutral oil to loosen it slightly, or remelt briefly at low power.

Melt 1/2 cup white chocolate chips in 15–30 second bursts at 50% power, stirring between each burst.
Use a spoon or a small piping bag to control the drizzle pattern.
Swap white chocolate for milk or dark chocolate if you prefer a less sweet finish.

Pressing & Slicing Tips

Firm pressing and chilling make slicing neat. After pressing, let the pan sit at room temperature or chill for 1 1/2 hours—refrigeration yields cleaner cuts.

Use a sharp knife warmed under hot water and wiped dry between cuts for smooth edges.

Grease the bottom of a measuring cup or use a buttered flat-bottomed cup to press evenly.
For straight edges, lift the parchment out of the 8×8-inch pan before slicing.
Cut into Servings: 9 servings for moderately sized bars, or halve the size for more pieces.

Tips for Success & Storage

Melt marshmallows slowly: Keep the heat low and stir constantly when melting the 10 ounce bag of marshmallows with 4 tablespoons unsalted butter—high heat scorches marshmallows and makes a grainy texture.

Press firmly for chew: Press the mixture down very tightly in the 8×8-inch pan (use greased parchment or a buttered flat-bottom cup) to create dense, chewy bars instead of loose, crumbly ones.

White chocolate care: Melt 1/2 cup white chocolate chips at 50% power in 15–30 second bursts, stirring between intervals to prevent overheating; alternatively use a double boiler for gentler heat.

Storage & make-ahead: Store in an airtight container at room temperature for a day or two; refrigerate to speed setting and for firmer slices. These bars keep well in the fridge for up to a week.

Equipment

8×8-inch square baking pan
parchment paper or aluminum foil
Large bowl
large heavy-bottomed pot
spatula or spoon
Microwave-safe bowl

Ingredients

5 cups Fruity Pebbles cereal
1 cup mini marshmallows
4 tablespoons unsalted butter
10 ounce bag large or mini marshmallows
1/2 cup white chocolate chips optional

Instructions

Line an 8×8-inch square baking pan with parchment paper or aluminum foil and grease it generously with cooking spray or butter.
Stir together the 5 cups Fruity Pebbles cereal and 1 cup mini marshmallows in a large bowl; set aside.
In a large, heavy-bottomed pot, melt 4 tablespoons unsalted butter over low heat. Add the 10 ounce bag of large or mini marshmallows and stir constantly until melted, then remove from heat.
Pour the cereal and mini marshmallow mixture into the pot with the melted marshmallows and butter, and stir until well combined.
Transfer the mixture to the prepared baking dish and press down tightly until the top is level. Let set at room temperature or refrigerate for 1 1/2 hours.
If using white chocolate chips, melt 1/2 cup white chocolate chips in the microwave at 50% power in 15–30 second intervals, stirring between intervals, then drizzle over the bars with a spoon.
Allow the drizzle to firm for about 20 minutes, or until the white chocolate has set, before cutting into bars.

Notes

Use an 8×8-inch pan to yield about 9 bars and press the mixture firmly into the pan for dense, chewy bars. Refrigerating speeds setting and produces firmer bars for cleaner slices. The white chocolate drizzle is optional—melt at 50% power in short bursts and stir between intervals to avoid scorching.
