Fruity Pebbles Marshmallow Bars Recipe — Quick No-Bake Treat

Fruity Pebbles Treats are a cheerful, no-bake dessert that’s quick to prepare and perfect for satisfying a sweet craving. These marshmallow cereal bars combine a delightful crunch with a chewy finish for a treat both kids and adults enjoy.

No-bake desserts are great when you want minimal cleanup and fast results. If you like simple sweets, try recipes like coconut fat bombs or no-bake chocolate peanut butter bars for more easy options.

These cereal bars are made similarly to classic Rice Krispie treats but use Fruity Pebbles to add bright colors and extra fruity flavor. The mix of plain Rice Krispies and Fruity Pebbles balances sweetness while keeping the bars light and crisp.

Fruity Pebbles Treats Ingredients

Gather the following ingredients to make these marshmallow cereal bars. Exact measurements and step-by-step directions are in the recipe card below.

• Salted butter
• Mini marshmallows
• Vanilla extract
• Salt
• Plain Rice Krispies cereal
• Fruity Pebbles cereal

Tools You Need

These no-bake treats are simple and require only a few common kitchen tools:

1. Large pot – a tall stock pot or large saucepan works well for melting butter and marshmallows and mixing in the cereal.
2. Baking pan – a 9 x 9-inch pan creates thick bars; a 9 x 13-inch pan will give you thinner bars if you prefer.
3. Parchment paper – lines the pan for easy removal and cleanup.

How to Make Fruity Pebbles Treats

1. Melt the butter in a large pot over medium-high heat.
2. Add half of the mini marshmallows and stir continuously until they melt into the butter.
3. Remove the pot from the heat.
4. Stir in the plain Rice Krispies, Fruity Pebbles, the remaining mini marshmallows, and vanilla extract.
5. Mix until everything is coated and combined, but not completely melted—some marshmallow pieces provide texture.
6. Press the mixture evenly into a parchment-lined 9×9-inch pan. Let cool at room temperature for about 30 minutes.
7. Lift the cooled slab from the pan using the parchment, cut into bars, and serve.

Tips for Success

These bars typically fill a 9×9 pan to the top and result in a thick, chewy texture. If you prefer a thinner bar, use a 9×13 pan. When pressing the mixture into the pan, use a piece of parchment or a lightly buttered spatula to press it evenly without compacting too hard—this preserves the light texture.

Why Use Plain Rice Krispies?

Fruity Pebbles are quite sweet on their own. Adding a cup of plain Rice Krispies balances the overall sweetness and adds a neutral crunch. You can make the recipe with only Fruity Pebbles if you prefer an extra-sweet bar, but combining the two cereals produces a more balanced flavor.

How to Cut the Bars

Lift the cooled slab from the pan using the parchment paper and place it on a cutting board. A long serrated knife works best to slice through the cereal and marshmallow cleanly. Wipe the knife between cuts or lightly grease a sharp knife if the marshmallow sticks.

Storage Instructions

Store the bars at room temperature in an airtight container for 7–10 days. Freezing is not recommended, as the texture can change once thawed.
