Ingredients You’ll Need

- 1/2 teaspoon baking powder: Helps the cookies rise, making them soft and fluffy.

- 3/4 cup unsalted butter, softened (170g): Adds richness and moisture to the cookies. Make sure it’s at room temperature for easy mixing.
- 3/4 cup granulated sugar (150g): Sweetens the dough. Brown sugar can also be used for a deeper flavor.
- 1 whole vanilla bean: Use the scraped seeds for a lovely vanilla flavor; it truly elevates the taste.
- 1 large egg, room temperature: Binds the ingredients together. Room temperature eggs ensure better incorporation into the dough.
- 2 teaspoons pure vanilla extract: Further layers the vanilla flavor. Always opt for pure extract over imitation for the best taste.
- For the buttercream:
- 3/4 cup unsalted butter, softened (170g): The base for a creamy frosting. Ensure it’s well-softened for easy mixing.
- 1/2 vanilla bean: Additional depth to the frosting. You can substitute with more extract if needed.
- 3 cups confectioners’ sugar, sifted (360g): Sweetens the frosting and results in a fluffy texture.
- 3 tablespoons heavy cream (45ml): Adds smoothness to the buttercream. You can substitute with milk if necessary.
- 1 1/2 teaspoons pure vanilla extract: Parallels the cookie flavors while adding sweetness.
- Salt to taste: Enhances the sweetness of the frosting nicely.
How to Make Giant Glazed Fruity Pebbles Cookies
Whisk Dry Ingredients: In a medium bowl, whisk together 2 1/4 cups all-purpose flour, 1/2 teaspoon baking powder, and 1/4 teaspoon salt until well combined. This step ensures that the leavening is evenly distributed.
Cream Butter and Sugar: Using a stand mixer or hand mixer, cream 3/4 cup unsalted butter and 3/4 cup granulated sugar on high speed for about 3 minutes until the mixture becomes light and fluffy. The air incorporated during this process will give your cookies a nice texture.
Add Vanilla and Egg: After the butter and sugar have creamed properly, scrape the seeds from 1 whole vanilla bean into the mixture and beat until creamy. Then add 1 large room temperature egg and 2 teaspoons pure vanilla extract, mixing on high for another minute until everything is well combined.
Mix Dry into Wet: Reduce the mixer speed to low and gradually add the dry mixture to the wet ingredients. Mix just until combined—overmixing can lead to tough cookies, and we want these to be soft and chewy!
Roll and Chill Dough: Divide the dough in half and roll each half out to about 1/4-inch thickness between two sheets of floured parchment paper. Once rolled out, place the dough in the refrigerator for at least 1-2 hours. This chilling time helps the cookies maintain their shape while baking.
Preheat Oven: While the dough chills, you can preheat your oven to 350°F (177°C). This makes sure the cookies will bake evenly once the dough is ready.
Cut Cookies: After chilling, remove the dough from the fridge and cut it into desired shapes using cookie cutters. Place them about 3 inches apart on lined baking sheets, as they will spread a little during baking.
Bake: Bake the cookies for 11-12 minutes, or until the edges are very lightly browned. You may smell that inviting aroma before they are done! Let the cookies cool completely on the baking sheets.
Make Buttercream: In a mixing bowl, beat 3/4 cup unsalted butter along with the scraped seeds of 1/2 a vanilla bean until fluffy. Then gradually add in 3 cups of sifted confectioners’ sugar, mixing on low speed to avoid a sugar cloud, followed by 3 tablespoons of heavy cream and 1 1/2 teaspoons of pure vanilla extract. Adjust the consistency with more cream if needed, and taste to add salt if desired.
Frost and Decorate: Once the cookies are cooled, generously frost them with your buttercream! Feel free to top them with additional Fruity Pebbles for an extra color burst and crunch.

Storing & Reheating
Store your cookies in an airtight container at room temperature for up to 5 days. For longer storage, you can place them in the refrigerator for up to a week. If you want to keep them even longer, freeze them in a single layer on a baking sheet before transferring to a zip-top bag, where they can last up to 3 months. To refresh, simply thaw at room temperature or warm in the microwave for about 10 seconds, but note that the texture might change slightly after freezing.
Chef’s Helpful Tips
- Avoid overmixing once you add the flour to keep your cookies tender.
- Make sure your butter is softened but not melted—this impacts the final texture.
- Use room temperature eggs to achieve a better emulsion in the dough.
- If the dough is too sticky to roll out, add a bit more flour to your work surface.
- For even more flavor, consider adding lemon zest into the dough or frosting.
- These cookies are great make-ahead treats for parties! Freeze undecorated cookies before frosting, then thaw and ice.
Giant Glazed Fruity Pebbles Cookies are a whimsical treat that will take you right back to your childhood. Their colorful appearance is matched only by their delicious flavor, making them perfect for any gathering or simply for satisfying your sweet cravings.

Recipe FAQs
Can I use other cereals besides Fruity Pebbles?
Absolutely! Feel free to experiment with different cereals for variation. Just keep in mind that certain cereals may add different textures and flavors. Just stick to something crunchy and sweet to complement the cookie base.
Can I make these cookies ahead of time?
Yes! You can prepare the cookie dough, roll it out, and chill it in the refrigerator up to a couple of days in advance. You can also freeze the formed cookies before baking. Just thaw them in the fridge before baking as per the instructions.
How do I achieve the best texture?
For soft and chewy cookies, avoid overbaking. Keep an eye on the edges, which should be just slightly golden while the centers might appear a bit underdone. They will firm up as they cool.
Can I make a smaller batch?
Certainly! Just halve the ingredients to make about 12 cookies. You may also adjust the baking time slightly, so keep an eye on them toward the end of the baking period.
