Fruity Pebbles Cookies are a fun and colorful twist on the classic sugar cookie, packed with vibrant fruity cereal and a gooey marshmallow center. These cookies are delightfully chewy with a crisp cereal coating that adds an exciting texture and bursts of fruity flavor in every bite. They make a perfect treat for kids and adults alike, especially for those who love nostalgic cereals reinvented in dessert form.
You’ll adore the way the creamy marshmallow melts inside, surrounded by soft cookie dough speckled with fruity cereal, while the outside crunch of coated cereal adds a playful contrast. These cookies are not just tasty but visually appealing, bringing joy to any cookie platter or festive occasion.
Ingredients
- 10 tablespoons (140g) unsalted butter, room temperature
- ½ cup (100g) granulated sugar
- 2 cups (80g) Fruity PEBBLES™ Cereal (divided)
- 1 large egg, room temperature
- 1 teaspoon vanilla extract
- 1¾ cups (218.75g) all-purpose flour
- 1 teaspoon baking soda
- ¼ teaspoon salt
- 8 large marshmallows
How to Create Your Fruity Pebbles Cookies
Step 1: Preheat Oven
Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
Step 2: Make the Cookie Dough
In a large bowl, cream the softened butter, sugar, and ½ cup of Fruity PEBBLES™ cereal on medium speed for about 2-3 minutes until fluffy. Mix in the egg and vanilla extract until combined.
Step 3: Add Dry Ingredients
Whisk the flour, baking soda, and salt in a separate bowl. Gradually stir into the wet mixture until combined. Gently fold in the remaining 1 cup of Fruity PEBBLES™ cereal.
Step 4: Assemble Cookies
Scoop 3-4 tablespoon balls of dough, then flatten each in your hand. Place one marshmallow in the center, and wrap the dough completely around it to seal in the marshmallow. Roll the dough ball in the remaining ½ cup of cereal to coat the outside. Place on the prepared baking sheet, spacing about 3 inches apart.
Step 5: Bake & Cool
Bake on the middle rack until marshmallow begins to peek through cracks on top, about 8-11 minutes. Allow cookies to cool on the baking sheet for a few minutes, then transfer to a wire rack.
My Best Tips for Success

-
Refrigerate extra dough balls while baking in batches to keep their shape.
-
Use parchment paper or silicone mats to prevent sticking and catch melted marshmallow.
-
Let cookies cool before attempting to move, as marshmallow filling is molten and sticky.
-
Press marshmallow gently into dough for even coverage.
-
Roll the cookie dough balls tightly to minimize marshmallow leaks.
Delicious Variations to Try
-
Try other fruity cereals like Fruity Pebbles, Trix, or Fruit Loops for unique flavors.
-
Add mini chocolate chips inside for a chocolatey surprise.
-
Drizzle with colored candy melts or melted chocolate for festive looks.
-
Sprinkle coarse sugar or colored sanding sugar on the outside before baking.
-
Mix a pinch of cinnamon or nutmeg into the dough for a subtle spice twist.
