Ingredients

Want to know the secret to getting those gorgeous rainbow colors throughout? It’s all about using the right cereal-to-dough ratio!
For the Cookie Dough:
- 10 tablespoons (140g) unsalted butter, room temperature
- 1/2 cup (100g) granulated sugar
- 1 large egg, room temperature
- 1 teaspoon alcohol-free vanilla extract
- 1 3/4 cups (218g) all-purpose flour
- 1 teaspoon baking soda
- 1/4 teaspoon salt
For the Fruity Fun:
- 2 cups Fruity Pebbles cereal, divided
- 8 large marshmallows (halal-certified)
The butter must be properly softened for easy creaming – I leave mine out for about 2 hours before baking. Room temperature egg combines much better than cold, so pull it out when you start gathering ingredients.
Step-by-Step Instructions

1. Prep your workspace. Preheat oven to 350°F and line two baking sheets with parchment paper. Set aside 1/2 cup Fruity Pebbles for rolling later.
2. Cream the base. In a large bowl, cream softened butter, sugar, and 1/2 cup Fruity Pebbles for 2-3 minutes until light and fluffy. The cereal will break down slightly – that’s perfect!
3. Add wet ingredients. Mix in egg and alcohol-free vanilla extract until completely combined. Don’t overmix or cookies will be tough.
4. Combine dry ingredients. Stir flour, baking soda, and salt into wet ingredients until just combined. Gently fold in 1 cup Fruity Pebbles for bursts of color.
5. Stuff with marshmallows. Scoop 3-4 tablespoons dough and flatten in your palm. Place one marshmallow in center and wrap dough completely around it, sealing edges.
6. Roll in cereal. Roll each stuffed dough ball in reserved Fruity Pebbles for extra crunch and color. Place 3 inches apart on prepared baking sheets.
7. Bake to perfection. Bake for 8-11 minutes until edges are set and marshmallow starts peeking through small cracks. Don’t overbake!
8. Cool carefully. Let cookies rest on baking sheet for 5 minutes before transferring to wire rack. The marshmallow centers will be molten hot!
