Cookie Monster Cookies

Bright blue Cookie Monster cookies stuffed with Oreos and loaded with chocolate chips—these fun, monster-sized treats are perfect for parties and cookie lovers!

What Are Cookie Monster Cookies?

Cookie Monster cookies are vibrant blue sugar cookies packed with chocolate chips, mini cookie pieces, and whole Oreos hidden inside, creating a soft, chewy, monster-sized treat that combines buttery cookie dough with crunchy Oreo centers and bursts of chocolate throughout.

I’ll never forget the first time my nephew saw these bright blue cookies cooling on the rack. His eyes went wide, and he literally started doing the Cookie Monster voice—”Me want cookie! Om nom nom!” That’s when I knew this cookie monster cookie recipe was a keeper.

These playful treats bring together everything kids (and let’s be honest, adults) love: a soft sugar cookie base, that iconic electric blue color, and enough chocolate and Oreo action to satisfy any cookie craving. If you’re into fun, over-the-top desserts, you’ll also love our Cookie Monster ice cream that pairs perfectly with these.

Why You’ll Love This Cookie Monster Cookie Recipe

Blue cookie monster cookies aren’t just adorable—they’re seriously delicious and surprisingly easy to make. Here’s why they’ll become your go-to party showstopper.

They’re ridiculously fun to make. There’s something oddly satisfying about smooshing a whole Oreo into cookie dough and sealing it up like a little treasure chest. Kids love helping with this part, and honestly, it never gets old.

The texture is perfection. Soft and chewy on the inside with slightly crisp edges, plus that surprise Oreo center that adds crunch and creaminess. The mix of regular chocolate chips and white chocolate chips creates little pockets of melty goodness.

They’re actually easier than they look. Despite their impressive appearance, these cookie monster cookies with oreos come together with basic pantry ingredients and a simple mixing process. No chilling required, no fancy techniques—just straightforward cookie magic.

One batch makes serious impact. Since these are monster-sized (about 3 ounces each!), ten cookies feel like a generous serving. Perfect for potlucks, bake sales, or when you want maximum wow factor with minimal effort.

I learned from King Arthur Baking that room-temperature butter is crucial for proper creaming—it should leave a slight indent when pressed but not be greasy or melty. This creates the fluffy texture that makes these cookies so tender. For more cookie techniques, check out our Crumbl cookie recipe guide.

What You’ll Need for Cookie Monster Cookies

This cookie monster cookie recipe starts with simple ingredients you probably already have—plus a few fun additions that make these cookies special.

Amount	Ingredient
⅔ cup (140g)	Butter, softened (regular or vegan)
½ cup (100g)	Granulated sugar
½ cup (100g)	Light brown sugar
1	Egg
1 Tablespoon	Vanilla extract
¼-½ teaspoon	Blue food coloring (gel works best for vibrant color!)
2 cups + 2 Tablespoons (265g)	All-purpose flour
¾ teaspoon	Salt
¾ teaspoon	Baking soda
¼-½ cup	Chocolate chips (mix of semisweet and white chocolate chips)
⅓ cup	Mini chocolate chip cookies (Chips Ahoy or Enjoy Life mini cookies work great)
14	Oreo cookies (10 for stuffing, 3-4 for chopping)

A note on the blue: Start with less food coloring and add more if needed. Gel food coloring gives you that brilliant Cookie Monster blue without making your dough too wet. I usually go with about ½ teaspoon for maximum blueness!

Flour matters: Spoon your flour into the measuring cup and level it off rather than scooping directly from the bag. This prevents dense, tough cookies—a lesson I learned the hard way after my first batch came out like hockey pucks.

Equipment You’ll Need

Here’s what’ll make your cookie-baking adventure smooth and easy:

Essential:

• Stand mixer or handheld mixer (makes creaming so much easier)
• Two large baking sheets
• Parchment paper (trust me, don’t skip this—cleanup is a breeze)
• Mixing bowls
• Measuring cups and spoons
• Cooling rack

Nice to Have:

• Cookie scoop (makes portioning the dough super consistent)
• Sharp knife for chopping Oreos
• Offset spatula for transferring cookies

How to Make Cookie Monster Cookies

Cookie monster cookies come together in about 30 minutes of active time, and watching them bake is honestly half the fun.

1. Prep your workspace. Preheat your oven to 350°F and line two large baking sheets with parchment paper. Grab 3-4 Oreos and your mini cookies, then chop them into rough chunks—no need to be precise here. Leave 10 Oreos completely whole for stuffing. (I like to set these aside in a separate bowl so I don’t accidentally chop them in a moment of enthusiasm!)

2. Cream the butter and sugars. In your mixer bowl, beat the softened butter with both sugars until the mixture looks light, fluffy, and almost doubled in volume—about 1-2 minutes. This step incorporates air that helps create tender cookies.

Add the egg, vanilla extract, and blue food coloring, mixing until everything’s evenly distributed and you’ve got that gorgeous Cookie Monster hue.

3. Add the dry ingredients. Toss in the flour, salt, and baking soda all at once, then mix on low speed until just combined. Here’s where you want to stop as soon as you don’t see any flour streaks—overmixing develops gluten and creates tough, cakey cookies instead of soft, chewy ones.

4. Fold in the good stuff. Using a spatula or wooden spoon, gently fold in your chocolate chips, chopped Oreos, and chopped mini cookies. The dough will be pretty loaded with mix-ins, which is exactly what we want!

5. Assemble the Oreo-stuffed cookies. This is the fun part! Scoop about 10 heaping tablespoons of dough onto your work surface. Take half of these dough balls and gently press a whole Oreo cookie slightly into the center.

Top each Oreo with another heaping tablespoon of dough, completely covering the cookie. Seal the edges so no Oreo peeks through—you want that surprise center when someone bites in. Each assembled cookie should weigh around 3 ounces and look impressively large.

6. Bake to perfection. Place 5 assembled cookies on each baking sheet, giving them plenty of room to spread. Bake one tray at a time for 8-10 minutes, until the edges look set and the tops appear dry rather than glossy.

They’ll seem slightly underdone in the center, but that’s perfect—they’ll continue cooking on the hot pan. Let them cool on the baking sheet for a full 10 minutes (they’re too delicate to move immediately), then transfer to a cooling rack.

Pro Tips for Perfect Blue Cookie Monster Cookies

Cookie monster cookies with oreos turn out best when you pay attention to a few key details I’ve learned through plenty of trial and error.

Temperature is everything. Your butter should be soft enough to leave a fingerprint but still hold its shape—around 65-68°F.

According to Serious Eats, butter that’s too warm (above 70°F) won’t hold air during creaming, resulting in flat, greasy cookies. If you’ve forgotten to soften your butter, cut it into small cubes and let it sit for 15-20 minutes rather than microwaving, which creates uneven warm spots.

Don’t skimp on the cooling time. I know it’s tempting to dig in right away, but those 10 minutes on the baking sheet are crucial. The cookies are still setting up, and the residual heat helps the Oreo center meld with the cookie dough. Move them too soon and they’ll fall apart or crack.

Measure your flour properly. Scooping directly from the bag compacts the flour, giving you up to 25% more than the recipe calls for. This creates dry, dense cookies. Always spoon flour into your measuring cup and level it off with a knife, or better yet, weigh it if you have a kitchen scale.

Chill for chewier cookies. If you prefer extra-thick, chewy cookies, refrigerate your assembled dough balls for 30 minutes before baking. Cold dough spreads less in the oven, creating taller cookies with chewier centers. I don’t always do this (because who wants to wait?), but when I remember, the results are noticeably better.

Troubleshooting Your Cookie Monster Cookies

Why are my cookies spreading too much? Your butter was probably too warm, or you didn’t measure your flour accurately. Make sure your butter is properly softened (not melted or greasy), and try adding 1-2 extra tablespoons of flour to your next batch. Also, baking on warm cookie sheets can cause immediate spreading—always use room-temperature pans.

What if my cookies are too cakey? You likely overmixed the dough after adding the flour, which develops gluten and creates a cake-like texture. Mix only until the flour disappears, then stop. Also check that you didn’t add too much flour by accidentally packing your measuring cups.

The Oreos keep poking through—help! Make sure you’re using enough dough to completely seal the Oreo. Each cookie should use about 2 heaping tablespoons total of dough. Press the top layer gently but firmly around the edges to seal. If your dough feels too stiff to seal easily, let it sit at room temperature for 5 minutes to soften slightly.

Why aren’t my cookies blue enough? Liquid food coloring tends to be less vibrant and can make your dough too wet. Switch to gel food coloring and don’t be shy—you can add up to ½ teaspoon for that true Cookie Monster electric blue. Add it gradually and mix well to check the color before adding more.

Fun Variations & Twists

Cookie monster cookie recipes are endlessly adaptable once you’ve mastered the basic technique.

Make them chocolate. Replace ½ cup of the flour with cocoa powder for double chocolate Cookie Monster cookies. They’ll be darker blue-gray instead of bright blue, but the flavor is incredible.

Try different cookies. Swap the Oreos for Nutter Butters, Thin Mints, or even Biscoff cookies. Mini peanut butter cups also make an amazing surprise center if you’re not an Oreo fan.

Go seasonal. Use red or green food coloring instead of blue for Christmas, orange for Halloween, or pink for Valentine’s Day. Add corresponding sprinkles to match the theme.

Make them vegan. Use vegan butter, a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water), vegan chocolate chips, and vegan Oreos (yes, regular Oreos are actually vegan!). The texture is nearly identical.

How to Serve, Store & Reheat

Serving these beauties: Cookie monster cookies are perfect at room temperature with a cold glass of milk. For an extra-special dessert, warm them for 10-15 seconds in the microwave and serve with vanilla ice cream—the Oreo center gets all melty and the chocolate chips get gooey. Divine.

Storage tips: Keep cookies in an airtight container at room temperature for up to 5 days. Layer them with parchment paper to prevent sticking. They actually taste even better on day two after the flavors have melded together.

Freezing for later: These freeze beautifully! Store baked cookies in a freezer-safe container for up to 3 months. Thaw at room temperature for about 30 minutes, or warm individual cookies in the microwave for 20-30 seconds. You can also freeze the unbaked, assembled cookie dough balls and bake them straight from frozen—just add 2-3 extra minutes to the baking time.

No-Waste Kitchen Magic

Got extra cookie dough or leftover ingredients? Here’s how to use every last bit:

Leftover cookie dough: Roll it into small balls (about 1 tablespoon each) and bake at 350°F for 6-8 minutes for mini Cookie Monster cookies—perfect for lunch boxes or portion control.

Extra Oreos: Crush them completely and use as an ice cream topping, mix into milkshakes, or layer into parfaits with whipped cream and berries.

Broken cookies: Crumble them over ice cream, fold into brownie batter, or blend into a cookies-and-cream milkshake. Broken Cookie Monster cookies also make an amazing crust for cheesecake—just pulse in a food processor with melted butter.
