Ingredients You’ll Need
The beauty of Fruity Pebbles Cake Mix Cookies is that you only need a handful of simple ingredients, but each one has a special role. From the cake mix base that creates that signature chewy texture, to the Fruity Pebbles cereal that brings both color and crunch, these cookies are a celebration of fun flavors and effortless baking.
- 1 box (15.25 ounces) white or vanilla cake mix: This is your shortcut to perfectly sweet, tender cookies without measuring out a ton of dry ingredients.
- 1/2 cup unsalted butter (melted): Melted butter adds richness and helps the cookies spread into that irresistible soft center.
- 2 large eggs: Eggs act as a binding agent, giving the cookies structure and a chewy bite.
- 1 teaspoon vanilla extract: Just a splash deepens the flavor and enhances the sweetness of both the cake mix and cereal.
- 1 cup Fruity Pebbles cereal: The star ingredient! These little gems add crunch, color, and a burst of fruity fun in every bite.
- 1/3 cup white chocolate chips (optional): For anyone who loves a creamy, melty surprise, white chocolate chips pair perfectly with the cereal’s flavors.
How to Make Fruity Pebbles Cake Mix Cookies
Step 1: Prep Your Baking Sheet
Start by preheating your oven to 350°F. Line a baking sheet with parchment paper, which makes cleanup a breeze and prevents the cookies from sticking. Taking a minute to do this ensures your Fruity Pebbles Cake Mix Cookies bake up with golden edges and easy removal.
Step 2: Mix the Dough
In a large mixing bowl, combine the cake mix, melted butter, eggs, and vanilla extract. Stir everything together until a soft, slightly sticky dough forms. The cake mix does most of the heavy lifting here, making the dough come together quickly with no guesswork.
Step 3: Fold in the Fun
Gently fold in the Fruity Pebbles cereal and white chocolate chips (if you’re using them). Be careful not to overmix—just a few folds are enough to distribute the cereal while keeping the colors vibrant and intact. This step is where the magic happens, and you’ll start to see all those rainbow flecks throughout the dough.
Step 4: Portion the Cookies
Using a cookie scoop or a heaping tablespoon, drop rounded balls of dough onto your prepared baking sheet. Be sure to leave about 2 inches of space between each one, as the cookies will spread a little. If you want even more crunch and color, sprinkle a few extra Fruity Pebbles right on top of each mound before baking.
Step 5: Bake to Perfection
Bake in the preheated oven for 10 to 12 minutes. You’ll know your Fruity Pebbles Cake Mix Cookies are ready when the edges look set but the centers are still a tad soft (they’ll firm up as they cool). This timing keeps them perfectly chewy in the middle with just a hint of crisp on the edges.
Step 6: Cool and Enjoy
Allow the cookies to cool on the baking sheet for 5 minutes—they’ll be fragile at first—then transfer them to a wire rack to cool completely. This resting time helps the final texture settle so you get that delightful contrast between tender cookie and crunchy cereal.
How to Serve Fruity Pebbles Cake Mix Cookies

Garnishes
For extra pizzazz, add a gentle sprinkle of Fruity Pebbles on top of each cookie right before baking. You can also drizzle a little melted white chocolate over cooled cookies for a bakery-worthy finish. Edible glitter or confetti sprinkles are another fun way to dress them up for parties or special occasions.
Side Dishes
While these cookies are a showstopper on their own, they’re even more fun served with a cold glass of milk, a scoop of vanilla ice cream, or alongside a creamy fruit dip. If you’re putting together a dessert spread, pair them with other colorful treats for a playful, rainbow-inspired table that’s sure to impress.
Creative Ways to Present
Turn Fruity Pebbles Cake Mix Cookies into an ice cream sandwich by scooping your favorite ice cream between two cookies. Stack them high on a tiered dessert stand for a birthday party, or wrap individual cookies in clear bags tied with bright ribbons as party favors. For a breakfast-themed brunch, serve them alongside mini cereal bowls for a whimsical touch.
Make Ahead and Storage
Storing Leftovers
To keep your Fruity Pebbles Cake Mix Cookies at their freshest, store them in an airtight container at room temperature. They’ll stay soft and chewy for up to five days, though the cereal may lose a bit of crunch after the first day or two. If you love that crispy texture, consider adding a few fresh Fruity Pebbles on top right before serving.
Freezing
These cookies freeze beautifully! Simply let them cool completely, then place them in a single layer in a freezer bag or airtight container. They’ll keep well for up to two months. If you’d like, you can also freeze the unbaked dough balls and bake them straight from the freezer—just add an extra minute or two to the baking time.
Reheating
To restore that fresh-baked warmth, pop a cookie in the microwave for about 10 seconds. This softens the cookie and brings out the aroma of the vanilla and butter. If you’re reheating several, a quick stint in a 300°F oven for a few minutes does the trick. Just be careful not to overheat, or the cereal may become overly crisp.
FAQs
Can I use a different flavor of cake mix?
Absolutely! While white or vanilla cake mix keeps the colors of the Fruity Pebbles vibrant, you can experiment with lemon, strawberry, or even Funfetti cake mix for a twist on the classic. Each flavor brings its own unique flair to the cookies.
Do Fruity Pebbles Cake Mix Cookies stay soft after baking?
Yes, these cookies are delightfully soft with just a bit of chew. The key is not to overbake them—the centers should look slightly underdone when you take them out of the oven, as they’ll continue to set as they cool.
Can I make these cookies gluten-free?
You can! Just swap in your favorite gluten-free vanilla or white cake mix. Be sure to double-check that your Fruity Pebbles cereal is labeled gluten-free as well, as formulations can vary.
Are the white chocolate chips necessary?
Not at all. The white chocolate chips are completely optional, but they add a creamy sweetness that pairs wonderfully with the fruity cereal. Feel free to leave them out or substitute with another favorite chip if you prefer.
How do I keep the Fruity Pebbles from getting soggy?
The best way is to fold in the cereal gently and bake the cookies soon after mixing. Storing the cookies in an airtight container also helps preserve some of the crunch. For maximum crunch, sprinkle extra Fruity Pebbles on top just before baking or serving.
