Fruity Pebbles Rice Krispie Treats

A recipe for Fruity Pebbles Rice Krispie treats, made with marshmallows, butter, and colorful Fruity Pebbles cereal. This rainbow twist on traditional Rice Krispie treats makes a fun addition to bake sales, birthday parties, and Pride Month celebrations.

Why Make These Fruity Pebbles Rice Krispie Treats?

Although I’m proud of my training and enjoy making fancy French pastries as much as the next pastry chef, I’m also a sucker for the childhood classics: oatmeal cream pies, M&M cookies, gummy bears, and lollipops. I also love Rice Krispie treats. In the past, I’ve developed all kinds of fun cereal treat recipes, like Nutella Rice Krispie treats and treats shaped like shamrocks, pumpkins, and miniature birds’ nests.

Every June, I find myself leaning into color—in my wardrobe, my IG account, and definitely in my kitchen. Anyone who knows me knows I love a rainbow recipe, and with Pride celebrations just around the corner, it seemed like a good time to add a new one to the mix.

This time last year I shared a recipe for striped rainbow rice krispie treats. This year, I decided to build my recipe around a rainbow-colored cereal. The result? These sweet, fruit-flavored treats made with Fruity Pebbles (talk about a childhood classic!!)

Featuring a rainbow-hued twist on the marshmallow-and-butter combo we all loved as kids, these cereal treats are sweet, crunchy, unapologetically colorful, and just in time for Pride.

Fruity Pebble Rice Krispie Treats Recipe Ingredients

To make these Fruity Pebbles Rice Krispie treats, start by gathering the following ingredients:

• Unsalted Butter – You’ll need 90 grams (6 tablespoons) of unsalted butter. No need to soften—it’ll be melted anyway!
• Marshmallows – You can make these treats with jumbo, large, or mini marshmallows. Use a scale to weigh out 300 grams, or about 10 1/2 ounces.

• Vanilla Extract – I prefer a good-quality vanilla extract from a brand such as Nielsen-Massey or Taylor & Colledge.
• Fine Sea Salt – A small amount of fine sea salt (or table salt) cuts the sweetness of the marshmallows and cereal.
• Fruity Pebbles – Fruity Pebbles are an American product, manufactured by Post. In the UK and elsewhere, you can purchase an imported box from Amazon (or a specialty retailer like Partridges in London) or use a similar brightly colored, fruit flavored cereal.

Tips and Tricks for Making Fruity Pebble Krispie Treats

A few things to keep in mind when making these rainbow cereal treats:

Don’t press too hard. When pressing the Fruity Pebbles mixture into the tin, press down gently with damp or oiled fingertips. Don’t press too firmly—packing the cereal into the tin will make the bars difficult to slice, and even more difficult to bite.

Prepare the tin. Do not skip the parchment preparation step. Lining the square tin with a criss-cross of parchment (and allowing an overhang on all sides) prevents the treats from sticking to the metal and  creates a “sling” that makes it super easy to transfer the slab to a cutting board in one piece.

Use a sharp knife. A sharp, well-oiled chef’s knife makes slicing a breeze.

Make-Ahead and Storage Suggestions

These Fruity Pebble Rice Krispie treats taste best on the day they’re made. Layer leftover treats between sheets of parchment or wax paper and store in an airtight container at room temperature for up to 3 days.
