Indulge in blue monster madness with these loaded cookies that take the viral TikTok sensation to new heights. These oversized treats feature a vibrant blue dough packed with chocolate chips, chopped cookies, and a gooey chocolate center that creates the perfect monstrous bite worthy of their Cookie Monster namesake.
I first made these with my niece after she showed me the TikTok version on her phone. Her eyes nearly popped out when she saw the finished cookies! We've made them together three times since then, with her insisting they're the "best cookies ever" while sporting an adorable blue-tinged smile from devouring them warm from the oven.
Cookie Creation Ingredients
- Butter creates that rich, tender base that good cookies depend on—make sure it's properly softened for the best texture
- Brown sugar adds depth and moisture thanks to its molasses content—the slight smokiness complements the chocolate perfectly
- White sugar balances the brown sugar and helps create those slightly crisp edges everyone loves
- Eggs bind everything together while creating lift during mixing—don't skimp on the creaming time here
- Vanilla provides that warm background note that enhances everything else—use pure extract for best results
- Blue food coloring transforms ordinary dough into Cookie Monster magic—gel colors work best for vibrant color without adding excess liquid
- Chocolate chips in both semisweet and white varieties add flavor contrast and visual appeal
- Chopped Oreos introduce that distinctive cocoa-cookie crunch that makes these extra special
- Crispy chocolate chip cookies add another texture dimension—those little store-bought crunchy ones work perfectly
- Chocolate discs create the melty middle that makes these cookies so irresistible—don't substitute regular chips here

Monster Making Method
Butter-Sugar BaseStart by creaming together your softened butter with both brown and white sugars. Give them a full minute to get acquainted in your mixer, watching as the mixture transforms from grainy to smooth. This foundation step is crucial for a cookie with the perfect texture—not too cakey, not too dense.
Fluffy Blue MagicAdd your eggs and vanilla, then let the mixer work its magic for a full three minutes. This extended creaming time incorporates air into the batter, creating cookies that rise beautifully in the oven. Once your mixture is light and fluffy, add enough blue food coloring to achieve that unmistakable Cookie Monster shade. I usually add a little at a time until it looks right—remember that the color will lighten slightly when you add the flour.
Dry Ingredients IntegrationMix in your flour, salt, and baking powder just until the flour streaks disappear. Overmixing at this stage can make your cookies tough, so show some restraint. The dough should look like blue velvet—smooth and consistent in color.
Mix-In MadnessGently fold in your chocolate chips and chopped cookies until they're evenly distributed throughout the dough. This is where these cookies start to take on their monster personality—loaded with goodies in every bite.
Chocolate HeartTake about two tablespoons of dough and flatten it in your palm. Place 2-3 chocolate discs in the center, then curl the edges of the dough up around the chocolate. Top with another two tablespoons of dough, sealing the edges to completely encase the chocolate. This hidden treasure creates that Instagram-worthy melty center when the cookies are broken open.
Final FlourishPress a few extra pieces of chopped cookies and chocolate chips onto the top of each dough ball. This not only makes them look more appealing but ensures that signature cookie monster texture is evident from the first glance.
Baking BrillianceSpace these monsters generously on your baking sheet—about six per standard sheet. They need room to spread without merging into one giant cookie (though that wouldn't be the worst thing). Bake until the edges are set but the centers still look slightly underdone, about 10-12 minutes. This gives you that perfect contrast between crisp exterior and gooey interior.
My first batch of these didn't have nearly enough blue food coloring, and my son took one look and said, "Mom, those aren't monster cookies, they're sad sky cookies." Lesson learned! Don't be shy with the color—Cookie Monster isn't pastel blue, he's vibrant and bold. Now we add the coloring until someone shouts "THAT'S COOKIE MONSTER BLUE!" which has become our official measuring technique.
Serving Suggestions
Serve these warm for maximum impact, when the chocolate center is still molten and utterly irresistible. They pair beautifully with cold milk (of course) but also with coffee for the adults. For an over-the-top dessert experience, sandwich softened vanilla ice cream between two cookies for a monster cookie ice cream sandwich that will make everyone's eyes bug out.
Creative Variations
Try stuffing the center with peanut butter cups instead of chocolate discs for a peanut butter lover's dream. During the holidays, use red or green food coloring and seasonal cookies for the mix-ins to create festive monster cookies. For a birthday celebration, fold rainbow sprinkles into the dough and use white chocolate in the center for a birthday cake-inspired variation.
Storage Solutions
These cookies are at their absolute best within the first 48 hours, when the contrast between crisp edges and soft interior is most pronounced. Store them loosely covered at room temperature to prevent them from becoming too soft. For longer storage, freeze completely cooled cookies in an airtight container with parchment between layers. When the monster craving strikes, thaw them at room temperature and warm briefly in the microwave for that fresh-baked experience.

Baker's Helpful Insights
- For perfectly round cookies, use a large round cookie cutter or glass to circle around each cookie immediately after baking
- If you don't have chocolate discs, chocolate bars broken into squares work in a pinch
- Chilling the dough balls for 30 minutes before baking helps control spreading if your first batch spreads too much
My daughter's preschool teacher requested these for the class party after seeing pictures on my phone. I was a bit worried about twenty kids with blue-stained mouths, but the teacher just laughed and said, "We're reading Monster books that week—it's thematic!" The cookies were such a hit that parents were texting me for the recipe before pickup time. Just be prepared to be known as "the monster cookie parent" forevermore once you bring these anywhere!
