Nothing brings out my inner child quite like the beloved Cookie Monster from Sesame Street. His enthusiastic “Me want cookie!” has echoed through generations, and today I’m sharing my take on a treat that would make even our favorite blue monster proud. These Big Blue Monster Stuffed Cookies are not just ordinary cookies – they’re oversized, vibrantly colored masterpieces stuffed with chocolate chips and bursting with personality.
I discovered this recipe during one of my late-night baking experiments when I was craving something that combined nostalgia with pure indulgence. The result? Cookies so delightfully messy and fun that they transport you straight back to childhood, complete with crumbs scattered everywhere and a smile plastered across your face.
What Makes These Cookies Special
Big Blue Monster Stuffed Cookies are essentially oversized sugar cookies that have been transformed into edible works of art. The magic lies in their vibrant blue color, achieved through food coloring, and their generous stuffing of chocolate chips that creates delightful pockets of melted chocolate in every bite.
Stuffed Cookies: Unlike traditional cookies where mix-ins are distributed throughout the dough, stuffed cookies feature a concentrated filling in the center, creating a surprise element that makes each bite exciting.
Cookie Monster Aesthetic: The deliberately messy, crumbly appearance mimics Cookie Monster’s enthusiastic eating style, making these treats as visually entertaining as they are delicious.
Oversized Format: These cookies are intentionally large – typically 4-5 inches in diameter – making them perfect for sharing or savoring as a substantial treat.

Step-by-Step Baking Process
My method for creating these show-stopping cookies involves careful attention to timing and temperature to ensure the perfect balance of crispy edges and chewy centers.
Preparation Phase
I always start by preheating my oven to 350°F (175°C) and lining two large baking sheets with parchment paper. This temperature ensures even baking without over-browning the vibrant blue color.
Room temperature ingredients are crucial for proper mixing. I take my butter and eggs out of the refrigerator about an hour before baking, which allows for smooth incorporation and prevents lumpy dough.
Creating the Perfect Dough
In my stand mixer bowl, I cream the softened butter with both granulated and brown sugars for approximately 3-4 minutes until the mixture becomes light and fluffy. This extended creaming time incorporates air, resulting in tender cookies.
Next, I add the eggs one at a time, followed by vanilla extract. The key here is patience – each egg should be fully incorporated before adding the next. This prevents the dough from becoming dense or separated.
The blue food coloring comes next, and I add it gradually while the mixer runs on low speed. I’ve learned that gel food coloring works better than liquid for achieving that vibrant Cookie Monster blue without thinning the dough excessively.
Dry Ingredient Integration
In a separate bowl, I whisk together flour, baking soda, and salt. I add this mixture to the wet ingredients in three additions, mixing just until combined after each addition. Overmixing at this stage can result in tough cookies, which is the opposite of what we want.
Assembly and Stuffing Technique
This is where the magic happens. I portion the dough into 12 large balls, each about 3 tablespoons worth. Using my thumb, I create a deep well in each dough ball, being careful not to break through the bottom.
Into each well, I pack a generous tablespoon of mini chocolate chips, sometimes adding a few mini marshmallows for extra gooeyness. Then I pinch the dough edges together, sealing the filling inside and rolling gently to reshape into a ball.

Baking to Perfection
I space the stuffed dough balls at least 3 inches apart on the prepared baking sheets – these cookies spread considerably during baking. Before sliding them into the oven, I gently press a few regular chocolate chips onto the surface of each cookie to create Cookie Monster’s characteristic googly eyes.
The baking time is crucial: 11-13 minutes for cookies that are set around the edges but still slightly soft in the center. They’ll continue cooking on the hot baking sheet after removal, so slight under-baking prevents them from becoming too crispy.
Advanced Techniques and Tips
Through countless batches, I’ve discovered several techniques that elevate these cookies from good to extraordinary.
Achieving the Perfect Blue
The intensity of blue food coloring can vary significantly between brands. I recommend starting with 10 drops and gradually adding more until you achieve that vibrant Cookie Monster blue. Gel coloring provides more intense color without affecting dough consistency.
Stuffing Distribution
For even stuffing distribution, I weigh my dough portions. Each cookie should contain approximately 2 ounces of dough and 1 tablespoon of filling. This consistency ensures uniform baking and prevents some cookies from being over-stuffed while others lack filling.
Temperature Control
Cookie dough temperature affects spread and texture significantly. If my kitchen is warm, I chill the shaped cookies for 15 minutes before baking. This prevents excessive spreading and maintains the cookies’ shape.

Troubleshooting Common Issues
Through my baking journey, I’ve encountered and solved several common problems that can arise when making these specialized cookies.
Color Problems
Pale Blue Result: This usually indicates insufficient food coloring. Add coloring gradually while mixing until you achieve the desired intensity.
Uneven Color Distribution: Ensure thorough mixing after adding coloring. Sometimes a few extra minutes of mixing resolves streaky appearance.
Texture Issues
Cookies Too Flat: This often results from warm dough or insufficient flour. Chill the dough and verify measurements.
Cookies Too Thick: Conversely, too much flour or cold oven temperature can prevent proper spreading. Check oven temperature with a thermometer.
Dry Texture: Overbaking is the primary culprit. These cookies should appear slightly underdone when removed from the oven.
Stuffing Challenges
Filling Leaks Out: This happens when the dough seal isn’t complete. Ensure dough edges are firmly pinched together and the seal is at the bottom of the cookie.
Uneven Filling Distribution: Consistent portioning of both dough and filling prevents this issue. Using a scale helps maintain uniformity.

Questions and Answers
Q: Can I make these cookies smaller for portion control? I absolutely recommend making smaller versions! Reduce the dough portions to about 1½ tablespoons each and decrease the filling to 2 teaspoons. Bake for 8-10 minutes instead of the full time. You’ll get about 18-20 smaller cookies that are perfect for parties or when you want just a taste of something sweet.
Q: What’s the secret to getting that perfect chewy texture? The key lies in not overbaking and using the right ratio of brown to white sugar. Brown sugar contains molasses, which keeps cookies moist and chewy. I also slightly underbake them – they should look set around the edges but still soft in the center when you remove them from the oven.
Q: My blue color turned out more purple than blue. What went wrong? This usually happens when the food coloring reacts with acidic ingredients or when you’re using liquid coloring instead of gel. Try using gel food coloring next time, and if your dough seems acidic, add a tiny pinch of baking soda to neutralize it. Some brands of vanilla extract can also affect color, so pure vanilla works best.
Q: Can I prepare the cookie dough ahead of time? Absolutely! I often make the dough up to three days ahead and store it in the refrigerator. You can even shape the cookies and freeze them for up to a month. Just add 1-2 extra minutes to the baking time if baking from frozen. This makes them perfect for busy schedules or planned events.
Q: Why do my cookies spread too much during baking? Excessive spreading usually indicates that your butter was too warm when mixing, your oven temperature is too low, or you need to chill the dough before baking. Make sure your butter is just softened (not melted), verify your oven temperature with a thermometer, and try chilling the shaped cookies for 15 minutes before baking.
Q: What’s the best way to achieve consistent cookie sizes? I use a large cookie scoop or ice cream scoop to portion the dough. Each cookie should be about 3 tablespoons of dough. If you don’t have a scoop, you can use a ¼ cup measuring cup and level it off. Weighing portions (about 2 ounces each) gives the most consistent results.
Q: Can I use natural food coloring instead of artificial? Yes, but the results will be different. Natural blue coloring often appears more muted and may require larger quantities. Spirulina powder creates a blue-green color, while butterfly pea flower powder gives a lovely blue that can change color when exposed to acidic ingredients. The flavor may be slightly affected with natural colorings.
Q: How do I prevent the chocolate chips from sinking to the bottom? Toss your chocolate chips in a light coating of flour before adding them to the cookie dough. This helps them stay suspended throughout the cookie. Also, avoid overmixing once you add the chips, as this can cause them to break down and sink.
These Big Blue Monster Stuffed Cookies represent more than just a sweet treat – they’re an experience that brings joy, nostalgia, and pure indulgence to anyone who encounters them. The combination of vibrant color, generous size, and surprise chocolate chip center creates a memorable cookie that satisfies both the eyes and the taste buds.
Whether you’re baking for a special occasion or simply want to brighten someone’s day, these cookies deliver on every front. The recipe is forgiving enough for beginning bakers yet offers enough complexity and customization options to keep experienced bakers engaged. Most importantly, they capture that childlike wonder and enthusiasm that Cookie Monster himself embodies – turning every bite into a celebration of simple pleasures and sweet moments.
