Cookie Monster Cookies: Blue, Stuffed & Loaded
Sesame Street has been a staple in homes across the US, UK, and Australia for over 50 years — and Cookie Monster has always been the most relatable character on the block. When blue stuffed cookies started flooding TikTok feeds a couple of years ago, every home baker suddenly wanted in. But most of the recipes floating around online produce cookies that look the part and taste… fine. Just fine.
This version fixes that. You get a properly buttery, chewy dough dyed a deep royal blue, loaded with chopped Oreos, crispy chocolate chip cookie pieces, and both white and semi-sweet chips — with a pool of molten milk chocolate hiding in the center. They bake in 12 minutes and the dough takes under 20 minutes to pull together.
Pro Tip
The most common mistake with stuffed cookies is using chocolate chips for the center — they’re engineered to hold their shape at high heat, so they never fully melt. You end up with a hard chocolate pocket instead of that lava-like pull. Use flat chocolate discs (sold as fèves, wafers, or A’Peels in most baking aisles) instead: 2–3 stacked in the center melt into a liquid pool at 350°F (175°C). No discs available? A chopped milk chocolate bar works just as well — cut it into quarter-sized chunks.
Blue gel food coloring gives a far more intense royal blue than liquid drops — you’ll need far less of it and the color won’t fade during baking. For the crispy cookie mix-in, Famous Amos or mini Chips Ahoy work perfectly; digestive biscuits are a solid swap if that’s what’s in your pantry. Chocolate discs (fèves or wafers) are stocked in most large supermarket baking aisles or online.

minutesIngredients
1 cup unsalted butter, softened (225g)
1 cup brown sugar, packed (200g)
1/2 cup granulated sugar (100g)
2 large eggs
2 tsp vanilla extract
2 3/4 cups all-purpose flour (340g)
1 tsp baking powder
1/2 tsp fine salt
1–2 tsp royal blue gel food coloring
3/4 cup semi-sweet chocolate chips (130g)
1/2 cup white chocolate chips (90g)
8 Oreo cookies, roughly chopped
1 cup crispy chocolate chip cookies, roughly chopped (e.g. Famous Amos or mini Chips Ahoy) (60g)
36 milk chocolate discs or wafers (for stuffing, approx. 3 per cookie)
Directions
- Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper. Cold baking sheets slow the spread — room temperature is fine, but never warm.
- Cream the butter and both sugars together for 1 minute on medium speed. Add the eggs and vanilla, then beat for a full 3 minutes — the mixture should turn noticeably pale and almost double in volume, which is what gives these cookies their lift.
- Add the blue gel coloring and mix until the dough is one even, deep blue with no streaks. Start with 1 teaspoon, check the color, and add more if needed — gel coloring intensifies slightly as it bakes.
- Add the flour, baking powder, and salt all at once, mixing on low just until no dry streaks remain. Stop the moment the flour disappears — overmixing here develops gluten and makes the cookies tough rather than chewy.
- Fold in the chocolate chips and roughly two-thirds of the chopped cookies by hand. Reserve the remaining third for topping — you want visible cookie chunks on the outside, not just buried inside.
- Scoop 2 tablespoons of dough, flatten it in your palm, and stack 3 chocolate discs in the center. Fold the edges up around the discs, then press another 2 tablespoons of dough on top and seal the seam firmly — any gap and the chocolate leaks out onto the tray.
- Press reserved cookie chunks and a few extra chips onto the top of each dough ball. This is purely visual but it matters — the cookies should look overstuffed and a little chaotic before they go in.
- Bake 6 cookies per sheet for 10–12 minutes. Pull them when the edges are just set but the centers still look underdone and shiny — they firm up on the tray as they cool, and an extra minute in the oven is the difference between chewy and cakey.
Variations
For an Oreo-stuffed version, replace the chocolate discs with a whole Oreo pressed into the center of the dough — let them cool completely before eating or the filling stays too soft to hold. For a peanut butter twist, swap the white chocolate chips for peanut butter chips and add 2 tablespoons of smooth peanut butter to the dough with the eggs.
Serving Suggestions
A glass of cold whole milk is the obvious move — the fat cuts through the richness of the chocolate center in a way that nothing else quite does. A scoop of vanilla bean ice cream pressed between two cookies turns these into a blue monster ice cream sandwich worth the mess. For a party table, stack them next to a bowl of extra Oreos and let people break the cookies open themselves.
FAQ
Can I make the dough ahead of time?
Yes — the dough keeps well in the fridge for up to 48 hours, tightly wrapped. Stuff and bake straight from cold; you may need to add 1–2 minutes to the bake time. I’ve tested this twice and the chilled dough actually spreads slightly less, giving you a thicker cookie.
Why did my blue color turn greenish after baking?
This happens with liquid food coloring, which fades under heat. Gel food coloring is far more stable — even at 350°F (175°C), the blue holds through the full bake. One teaspoon of a quality royal blue gel is all you need.
Can I freeze the baked cookies?
Absolutely — once fully cooled, layer them in a freezer-safe container with parchment between each cookie and freeze for up to 3 months. Thaw at room temperature for about 30 minutes, or warm them for 15–20 seconds in the microwave to get the center soft again. Makes you wonder what else you could stuff in that center before freezing a batch…
