Milk Bar, one of New York City’s most iconic bakeries, is all about treating yourself every day, and these limited-edition, ready-to-bake cookies are the easiest way to do just that! The soft, gooey vanilla cookie base is studded with chunks of salty-sweet cornflake crunch, melty chocolate chips, and marshmallow bits for an explosion of flavor and texture in every bite. Plus, you’ll get that fresh-from-the-bakery experience without leaving your home—that’s our kind of self-care! Nutrition values are representative of one cookie.

Review summary

Updated on Dec 2025
  • Flavor: Many enjoyed the taste, but some found them overly sweet. The marshmallows and cornflakes add unique textures and flavors.
  • Ease of prep: Follow package instructions carefully; many found the suggested baking time too long, resulting in overcooked cookies.
  • Suggestions: Reduce baking time to 9-12 minutes for softer cookies. Chill dough before baking to prevent spreading.
  • Texture: Cookies tend to bake very thin and crispy. Some enjoyed the crunch, while others preferred a thicker, chewier cookie.
  • Baking tips: Use parchment paper instead of greasing the pan. Avoid dark baking sheets and watch closely to prevent burning.

The directions are misleading. If you give the cookies to a person who has never baked before, the cookies would be burnt to a crisp. It said cook the cookies at 350 until edges are golden, with a timeframe of 18-21 minutes. That's WRONG! I put it in for 12 minutes, and the edges were just right. HOWEVER, here are tips to make the experience better: 1. chill the dough in the fridge until really cold OR chill the baking sheet, otherwise the dough would spread a lot; 2. do not use a dark colored baking sheet, 3. instead of greasing, use parchment paper. The marshmallows are a nice touch, but it sticks to the sheet, and it could make the cookie chewy.

They were pretty good. I knew they would taste a little different, what with cornflakes and breakfast cereal mixed in, but I'm not sure it works. Tasty, no regrets about getting them, but not sure I would call them fantastic. I think sometimes there would be a "fruity flavored" cornflake in with the chocolate chips and that create a bit of taste dissonance. Not sure you could do anything but see if the vendor has a different flavor cookie.

Buttery delicious cookies. If you cook them (did this accidentally) at a higher heat, they flatten out and are super crunchy.

They were good but very sweet. I added pecans to some and they were better.

Tastes great, but like the other flavor I cooked less than the specified time and they still were too brown.

These come out as a very thin crisp cookie. They were good but thinner than I was expecting.
