I have had this love affair with Momofuku Milk Bar, or simply Milk Bar, for quite some time now. I first learned about it through a mild obsession with David Chang and his Momofuku restaurant empire, which first started in New York City. Milk Bar is the brain child of Christina Tosi. She started working in David’s restaurant as the head pastry chef and was then given the opportunity to open and run an independent bakery outside of the restaurants. As “sister bakery of the Momofuku restaurant group”, Milk Bar has expanded outside of New York City to Washington, DC and even Toronto. Christina is now also a judge on the wildly successful food show, MasterChef. 

Christina’s unique ingredients, which make up some of her most infamous treats, such as Crack Pie and Cereal Milk Ice Cream is really what put her on the map. She balances the combination of sweet and salty so perfectly in each recipe.  That is why I love these cookies from their first cookbook, Momofuku Milk Bar

The Cornflake Crunch, another amazing Tosi ingredient, gives these cookies a decadent, crispy texture. The marshmallows give them a wonderful richness. And don’t even get me started with the addition of mini chocolate chips. 

These are definitely more of a crunchy cookie as opposed to a soft cookie, and it’s one you need to make immediately.

Let’s start by making the Cornflake Crunch that will go into these cookies.

Spread a thin layer on a parchment or silicone mat lined baking sheet. 

Bake at 275 degrees fahrenheit for 20 minutes.

Cool Cornflake Crunch completely before incorporating into your cookies or storing in an airtight container.

This will keep for 1 week in the fridge or 1 month in the freezer.

Now onto making the cookies!

With the mixer on low, add your egg.

Then add your vanilla. 

Beat for another 7-8 minutes on medium-high.

The 7-8 minutes is totally worth it and important.

The batter will be so light and fluffy. Almost like frosting!

While your sugar and butter is beating, combine your flour with baking powder in a small bowl.

Add your baking soda.

Mix until just combined. Do not overmix. 

You shouldn’t mix for more than 1 minute.

Add in mini chocolate chips.

Next add in 3 cups of Cornflake Crunch. 

Mix again until just incorporated. Do not overmix.

Cover bowl with saran wrap and refrigerate for at least 1 hour and up to 1 week. 

Do NOT bake your cookies from room temperature. 

They will not hold their shape and bake into a puddle of crispy nothing. 

Trust me on this.

Should look like so.

Space each dough circle 4 inches a part, as these cookies spread out quite a bit. 

Bake in a 375 degree fahrenheit oven for anywhere from 8 – 15 minutes, until the edges become golden brown and cookies are just beginning to brown toward the center.

You really do need to watch these cookies, as baking times vary depending on your oven. 

It’s very easy to overbake these cookies, so keep an eye on them in the oven.

The perfect blend of sweet, salty and savoury.

Christina Tosi, you are an incredible genius.

Enjoy!
