Ingredients

Here’s everything you need to create these chewy, colorful cookie sandwiches. Ingredients are divided into two parts: one for the cookies and one for the buttercream filling. All measurements are listed again in the recipe card later.

For the Fruity Pebbles Cookies:

• 2 ½ cups (312g) all-purpose flour – Spoon and level for accuracy.
• ½ teaspoon baking soda
• ½ teaspoon salt
• 1 cup (226g) unsalted butter, softened to room temperature
• ¾ cup (150g) granulated sugar
• ½ cup (100g) packed light brown sugar – Adds chewiness and a subtle caramel note.
• 1 large egg – Room temperature helps with mixing.
• 1 teaspoon pure vanilla extract
• 1 ½ cups (about 60g) Fruity Pebbles cereal – Folded in at the end to retain their crunch and shape.

For the Vanilla Buttercream Filling:

• ½ cup (113g) unsalted butter, softened
• 1 ¾ cups (210g) powdered sugar, sifted
• 1 tablespoon heavy cream or milk – Adjust for consistency.
• 1 teaspoon vanilla extract
• Pinch of salt – Balances sweetness.

How to Make Fruity Pebbles Cookie Sandwiches: Step-by-Step

Step 1: Whisk the Dry Ingredients

In a medium bowl, whisk together the flour, baking soda, and salt. Set aside. This ensures the leavening and salt are evenly dispersed in the dough.

Step 2: Cream the Butter and Sugars

In a large bowl, beat the softened butter, granulated sugar, and brown sugar with a hand or stand mixer on medium speed for 2–3 minutes. The mixture should be light and fluffy. This step builds the base of your cookie’s texture.

Step 3: Add Egg and Vanilla

Beat in the egg and vanilla extract until the mixture is smooth and well combined. Scrape down the sides of the bowl as needed.

Step 4: Combine Wet and Dry Ingredients

Slowly add the dry ingredients to the wet mixture, mixing on low speed. Mix just until the flour disappears—avoid overmixing to keep the cookies soft.

Step 5: Fold in Fruity Pebbles

Gently fold in the Fruity Pebbles cereal with a spatula. Be careful not to crush them too much—you want them to stay whole and visible for color and texture.

Step 6: Chill the Dough

Cover the bowl with plastic wrap and chill the dough in the refrigerator for 30 minutes. Chilling helps prevent the cookies from spreading too much and keeps them thick and chewy.

Step 7: Scoop and Bake

Preheat the oven to 350°F (177°C). Line baking sheets with parchment paper.

Scoop the dough into 1.5–2 tablespoon portions and place them 2 inches apart on the baking sheets.

Bake for 10–12 minutes, or until the edges are lightly golden and the centers look just set. Do not overbake—they’ll continue to cook slightly as they cool.

Step 8: Cool Completely

Let the cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool fully before assembling.

Make the Filling

Step 9: Cream the Butter

In a clean bowl, beat the softened butter on medium speed until smooth and creamy, about 1–2 minutes.

Step 10: Add Powdered Sugar

Gradually add powdered sugar, ½ cup at a time, beating well after each addition.

Step 11: Finish the Buttercream

Add vanilla, salt, and 1 tablespoon of cream or milk. Beat on high for 1 minute until light and fluffy. Add more cream if needed to adjust consistency.

Assemble the Cookie Sandwiches

Step 12: Match and Fill

Pair cookies of similar size together. Spread or pipe a generous tablespoon of filling onto the flat side of one cookie. Top with the matching cookie and gently press until the filling spreads to the edges.

Step 13: Chill (Optional)

For a firmer sandwich, refrigerate for 10–15 minutes before serving. This helps the buttercream set and makes the cookies easier to handle.

Variations & Ideas

• Use Marshmallow Filling: Swap buttercream for marshmallow fluff for a cereal-and-milk inspired twist.
• Add White Chocolate Chips: Fold ½ cup white chocolate chips into the dough for extra richness.
• Make Mini Sandwiches: Use a smaller scoop and reduce bake time slightly for bite-sized treats.
• Use Other Cereals: Try Cocoa Pebbles or Cap’n Crunch for a flavor change.
• Roll Edges in Cereal: For more crunch and color, roll the exposed frosting edges in extra Fruity Pebbles before chilling.

FAQs

Can I make these ahead of time?
Yes. You can bake the cookies and refrigerate them (unfilled) for up to 3 days. Assemble before serving for best texture.

Can I freeze them?
The cookies freeze well. Wrap unfilled cookies tightly and freeze for up to 2 months. Thaw and fill when ready.

What can I use instead of Fruity Pebbles?
Try Cocoa Pebbles, Trix, or even crushed freeze-dried fruit for a different texture and flavor.

Is it okay to skip chilling the dough?
Chilling is important—it keeps the cookies thick and prevents spreading. If you’re short on time, chill at least 15 minutes.

Can I use store-bought frosting?
You can, but homemade frosting offers better flavor and texture. Store-bought may be sweeter and less stable.
