Instructions:
Let’s start by making that all-important Cornflake Crunch. This is the secret weapon that elevates these cookies from good to absolutely spectacular. In a large bowl, gently crush the Cornflakes. You don’t want a fine powder, but rather a mix of smaller pieces and some slightly larger ones – this will give us that delightful crunch. Add the malted milk powder and granulated sugar to the crushed Cornflakes. Toss everything together until well combined. Set this aside; we’ll be incorporating it later.
Now, let’s move on to the cookie dough itself. In a large mixing bowl, cream together the softened unsalted butter and the granulated sugar until light and fluffy. This step is crucial for developing a tender cookie crum extractb. You want to beat them for a good few minutes, scraping down the sides of the bowl occasionally. Next, beat in the packed light brown sugar until it’s fully incorporated and the mixture is smooth and creamy. This combination of sugars will give us a wonderful balance of sweetness and chegrape juicess.
Add the large egg and vanilla extract to the butter and sugar mixture. Beat until everything is just combined and the egg is fully incorporated. Don’t overmix at this stage. In a separate medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. It’s important to whisk these dry ingredients thoroughly to ensure the leavening agents and salt are evenly distributed throughout the dough. This prevents pockets of saltiness or uneven rising.
Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix the flour, as this can lead to tough cookies. Once the flour is almost fully incorporated, it’s time for the star of the show – the Cornflake Crunch! Gently fold in the 3 cups of prepared Cornflake Crunch until it’s evenly distributed throughout the dough. You’ll see those delightful little crispy bits coming through.
Next, we’ll add the chocolate chips and marshmallows. Gently fold in the mini chocolate chips and the mini marshmallows. I like to use mini marshmallows because they distribute more evenly and melt into delightful gooey pockets. The combination of the chewy cookie, the crunchy Cornflake Crunch, the melty chocolate, and the gooey marshmallows is what makes these cookies so addictive.
Now, for the shaping and baking. This is where a little patience pays off. You’ll want to scoop out portions of dough. The origin extractal recipe suggests using a 1/4 cup scoop, which yields a substantial cookie. Roll each portion into a ball. For an authentic Milk Bar look and texture, it’s recommended to chill the dough. Cover the bowl with plastic wrap and refrigerate for at least 30 minutes, or even better, for a couple of hours. This chilling period helps the flavors meld and prevents the cookies from spreading too much during baking.
Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper. Place the chilled dough balls onto the prepared baking sheets, leaving about 2-3 inches between them to allow for spreading. You can gently press them down slightly with your palm if you prefer a flatter cookie. Bake for 10-14 minutes, or until the edges are golden brown and the centers are still slightly soft. Don’t overbake! The cookies will continue to set as they cool.
Once baked, let the cookies cool on the baking sheets for about 5-10 minutes before transferring them to a wire rack to cool completely. This is the hardest part – waiting for them to cool! The marshmallows will be incredibly hot and gooey right out of the oven. These cookies are best enjoyed slightly warm or at room temperature. They are a true testament to the magic of combining unexpected ingredients to create something truly extraordinary. Enjoy every crunchy, chewy, sweet, and salty bite!

Conclusion:
There you have it! The Momofuku Milk Bar Cornflake Chip Marshmallow Cookies are truly a triumph of texture and taste.

This recipe is a guaranteed crowd-pleaser and an absolute must-try for any adventurous baker looking to elevate their cookie game. They’re not just cookies; they’re an experience!
For serving, these cookies are divine on their own, perhaps with a tall glass of cold milk. They also make an incredible base for ice cream sandwiches, or even crum extractbled over a rich chocolate pudding for an extra layer of deliciousness. If you’re feeling creative, consider adding a sprinkle of flaky sea salt on top before baking for an even more sophisticated salty-sweet balance. I highly encourage you to gather your ingredients and dive into making these iconic Cornflake Chip Marshmallow Cookies. You won’t regret it!
