  • Granulated Sugar (½ cup): For the perfect balance of sweetness and crispness.
  • Large Egg (1): Helps bind the ingredients together while keeping the cookies soft.
  • Vanilla Extract (1 tsp): Enhances all the sweet flavors in the cookies.
  • All-Purpose Flour (1 ¼ cups): The base that gives these cookies structure.
  • Baking Soda (½ tsp): Ensures your cookies spread just the right amount.
  • Salt (½ tsp): A little salt sharpens the sweetness and balances the flavors.
  • Old-Fashioned Oats (1 ½ cups): Adds a chewy texture to contrast the marshmallows.
  • Fruity Pebbles Cereal (1 cup): The star ingredient that brings bright colors and a crunchy bite!
  • Mini Marshmallows (1 cup): These melt into gooey pockets of sweetness throughout the cookies.

How to Make Fruity Pebble Marshmallow Cookies

Here’s a step-by-step guide to baking these cookies to perfection:

Step 1: Preheat and Prepare

Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper to prevent sticking.

Step 2: Cream the Butter and Sugars

In a large mixing bowl, beat the softened butter, brown sugar, and granulated sugar together until the mixture is fluffy and light. This step is crucial for creating a soft cookie texture.

Step 3: Add Wet Ingredients

Beat in the egg and vanilla extract until well combined. Scrape down the sides of the bowl to ensure everything is mixed evenly.

Step 4: Combine Dry Ingredients

In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add this mixture to the wet ingredients, mixing just until incorporated.

Step 5: Fold in the Fun

Gently fold in the oats, Fruity Pebbles, and marshmallows. Be careful not to overmix, or you risk crushing the cereal!

Step 6: Scoop and Bake

Using a cookie scoop or tablespoon, drop rounded balls of dough onto the prepared baking sheet, spacing them about 2 inches apart. Bake for 10–12 minutes, or until the edges are golden brown.

Step 7: Cool and Enjoy

Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely. Enjoy them warm or at room temperature!

Frequently Asked Questions

Can I use quick oats instead of old-fashioned oats?

Yes, you can! Quick oats will give the cookies a slightly finer texture. However, old-fashioned oats provide a chewier bite, which complements the gooey marshmallows perfectly.

What if I don’t have Fruity Pebbles?

No worries! You can substitute another colorful cereal, like Froot Loops or Trix. Each will bring its unique twist to the recipe.

How do I store these cookies?

Store the cookies in an airtight container at room temperature for up to 5 days. For longer storage, freeze them in a freezer-safe bag for up to 3 months.

Can I make the dough ahead of time?

Absolutely! You can refrigerate the dough for up to 48 hours. If it’s too firm after chilling, let it sit at room temperature for 10–15 minutes before scooping and baking.

Why did my marshmallows melt too much?

Marshmallows tend to melt if they’re too close to the edge of the cookies. When shaping your dough, try tucking the marshmallows toward the center for better results.

Can I add chocolate chips?

Yes! Adding white chocolate chips or milk chocolate chips will take these cookies to the next level.
