I absolutely love cookies! They’re are the perfect amount and combination of sweetness and texture. If you are a cookie fan too, some of our other favorites are Monster Cookies and Lemon Glazed Cookies.

Fruity Pebble Cookies

Lately, I have been on a major cookie kick. I blame Crumbl Cookies and their big, warm cookies. Normally that’s not a problem for me because I live in the California Bay Area and Crumbl started out in Utah, but recently a Crumbl location opened up not too far from me. It’s far enough that I don’t like to make the drive unless they happen to be serving up one of my favorite flavors that week, but it’s still dangerous enough.

I really enjoy making cookies fresh at home anyway. The process of creaming butter and sugar together then adding the other ingredients and my favorite mix-ins is just so relaxing and fun, not to mention less expensive since you can make a batch of cookies for the cost of 1 or 2 of the cookies at any of those gourmet cookie shops.

I haven’t actually ever seen a Crumbl Fruity Pebbles Cookie, but when I first made these, I did them without the frosting. While they were good, they just felt like they were missing something and turned to Crumbl for inspiration. I had seen other fruity pebble cookies with marshmallows and some dipped in white chocolate, but then I put on my “what would Crumbl do?” thinking cap and decided they would probably add a layer of frosting.

I love frosted cookies and the very first batch I made where I added that element were an immediate sensation! The bit of chewy crunch from the cereal gives an amazing textural element to the cookie itself. And the creamy, tangy sweet frosting which is made with a little cream cheese and marshmallow fluff is on point and the perfect compliment to the cookie base!

I’m going to have to recreate a couple of my other favorite Crumbl flavors like caramel popcorn cookies and cinnamon swirl cookies next! If you have been to Crumbl, I would love to know what your favorite Crumbl cookies are in the comments below!

What You’ll Need

  • Butter: I always use salted butter in my baking. I know it’s risky business softening butter in the microwave, but I have found that if I heat it for 10 seconds, then flip the sticks over and heat another 4-5 seconds, it ends up perfectly soft without melting into a puddle.
  • Sugar: You will use both granulated and brown sugar in this recipe, plus some powdered sugar if you go the frosting route.
  • Eggs: These are for binding, chewiness, and flavor as the egg yolks add a little richness to the dough.
  • Vanilla: Good vanilla extract makes any baked good taste better!
  • Salt: Don’t be afraid to add salt! A good cookie NEEDS a little salt to balance out the sweetness.
  • Baking Soda: Because, science. This ingredient gives a little lift to cookies. It is what helps them spread out just a bit while baking.
  • Baking Powder: Again, science. This is also going to help the cookies rise a bit and stay soft. Remember, powder puffs, soda spreads when trying to remember how each affects your baking.
  • Flour: Keep it simple with regular all-purpose flour. That’s all you need for these cookies!
  • Fruity Pebbles Cereal: This is a childhood classic! You won’t use the entire box, so you can definitely sit down to enjoy a bowl of cereal with milk later.
  • White Chocolate Chips: I just love white chocolate and thought they would work well in these cookies. You can omit if you feel like it, but I thought they were delicious.

How to Make Fruity Pebble Cookies

  1. Cream the butter and sugar together: Creaming butter and sugar together is an essential step for any baker. It just means letting them beat for a good 2-3 minutes until they lighten in color. It’s definitely easiest to do if you have a stand mixer with a paddle attachment, but can totally be done with a hand mixer as well.
  2. Add eggs and vanilla: Mix again, scraping the bottom and sides of the bowl so these get evenly incorporated into the cookie dough.
  3. Mix in the flour, baking powder, baking soda, and salt: In older recipes, you might see these referred to as the “dry ingredients” rather than listing them all out again. Be careful not to overdo it on this step. You only want to stir the ingredients until there are just streaks of flour left in the dough.
  1. Stir in the fun stuff! Very gently stir in the fruity pebbles and white chocolate chips so as not to completely crush the cereal.
  1. Get ready to bake! Use a large cookie scoop to scoop out mounds of dough and shape them into balls. I like to roll each ball of cookie dough in a bowl filled with even more fruity pebbles for some extra color and texture although you definitely skip this extra step if you wanted.
  1. Bake at 350 degrees: Then put the cookies on the prepared baking sheets, about six to a sheet, and bake for about 12 minutes.
  1. Make the frosting: While the cookies are baking and starting to cool, go ahead and make the frosting by beating butter until creamy, then adding marshmallow fluff and powdered sugar. Beat again until smooth.
  2. Add the frosting: I like to let the cookies cool just a bit and then pipe the frosting on in swirls starting in the center and working out toward the edges. Sprinkle a few additional Fruity Pebbles on top for decoration.

How do I keep my cookies from getting hard?

When you mix the dough after you add flour, gluten is formed. The more you mix, the more gluten you’ll have, which makes tough cookies. Just be careful not to over mix the dough after you add the flour. Only mix until just streaks of flour is left in the dough.

How do I keep my cookies from spreading so much?

Stay away from non-stick spray or butter as those create an overly greasy base for the cookies, which causes them to spread. I like to line my cookie sheet with parchment paper. A silicone baking mat works great too. You could also refrigerate your dough for 30 minutes to an hour to let the butter in the dough firm up a bit, although I don’t find that necessary with these cookies.

Can I freeze these cookies?

If you want to make these ahead and freeze them, the cookies freeze well without the frosting on top. Just freeze for up to 2-3 months in an airtight container, then thaw on the counter at room temperature before frosting and serving.

How do I store my Fruity Pebble Cookies?

Because these cookies have a cream cheese frosting on top, they should be stored in the fridge if they aren’t eaten within a few hours. An alternative is to only frost the cookies you plan to eat and just store the frosting in the fridge, keeping the unfrosted cookies in an airtight container on the counter until ready to frost and decorate.

Is there another frosting option?

Another option instead of frosting these cookies would be to dip half of each cookie into melted white chocolate for more of a candy finish.

Ingredients

Cookie

  • 1 1/2 cups salted butter softened
  • 1 cup granulated sugar
  • 1 cup packed brown sugar
  • 2 eggs
  • 1 Tablespoons vanilla
  • 3 3/4 cups all-purpose flour
  • 2 teaspoons baking soda
  • 1 teaspoon baking powder
  • 1 teaspoon salt
  • 4 cups fruity pebbles cereal divided
  • 1 cup white chocolate chips

Frosting (optional)

  • 16 ounces cream cheese, room temperature
  • 7 ounces marshmallow cream
  • 2 cups powdered sugar

Instructions

  • Preheat oven to 350 degrees F. Line two baking sheets with parchment paper.
  • In a large bowl, beat the butter and sugars for 2-3 minutes until creamy and light. Add the eggs and vanilla and beat again, scraping the bottom and sides of the bowl.
  • Add the flour, baking soda, baking powder, and salt. Mix just until combined. Stir in 2 cups of the fruity pebbles and the white chocolate chips.
  • Use a large cookie scoop to scoop out approximately 1/2 cup mounds of dough and shape them into balls. Roll each ball of cookie dough in a shallow bowl filled with the remaining fruity pebbles.
  • Arrange the cookies on the prepared baking sheets, six to a sheet. Press them down to flatten to about 1-inch thick.
  • Bake for 11-13 minutes until set around the edges. Let cool on the pan for 5 minutes before transferring to a wire rack.
  • Meanwhile, make the frosting by beating the cream cheese until smooth.
  • Add the powdered sugar and marshmallow cream, then beat until creamy and smooth. Transfer to a piping bag fitted with a medium round tip or a large ziploc bag. Use scissors to snip off one corner for piping, if using the ziploc bag.
  • Once the cookies have cooled somewhat but are still warm, pipe the frosting on in swirls starting in the center and working out toward the edges. Sprinkle a few additional Fruity Pebbles on top for decoration.
