Momofuku Mash-Up Cookies

April 2, 2012 · 7 comments in Cookies

Mmmmm, Chocolaty chunky cookie goodness. That’s what we want.

Chocolate cake crumbs?

Caramelised cornflake crumbs?

Chocolate chips?

Check, check, check! Christina Tosi is a total sugar wizard!

You must not over bake these cookies.

You must serve them warm:
Microwave, oven or on top of the toaster for a bit = Good idea
But don’t skewer them and try to warm them over a fire; smoky cookies – does that sound nice? Well I’ll tell you now, it’s not, just stick to toasting marshmallows over the fire for now (then sandwich warm cookies around them).

Can’t type more, too many cookies eaten, chocolatey hands don’t mix well with keyboards.

Momofuku Mash-Up Cookies

adapted a little from Momofuku Milkbar – here and here

1 cup (8 oz / 220g) butter
1 1/2 cups (12 oz / 325g) sugar
1/4 cup (3 oz / 85g) glucose
1 egg
1/4 tsp vanilla extract
2 ounces 55% chocolate, melted
1 1/4 cups (5.8 oz / 160g) flour
3/4 cup (3 oz / 85g) cocoa powder
3/4 tsp baking powder
1/4 tsp baking soda
1 tsp kosher salt

1/2 cup (3.5 oz / 100g) chocolate chips (I used half semisweet and half white)
Chocolate crumbs
3 tbsp flour
1/4 teaspoon cornstarch
2 tbsp sugar
3 tbsp cocoa powder
1/4 teaspoon kosher salt
4 1/2 tsp (0.75 oz / 20g) butter, melted

Cornflake crumbs

1 1/4 cups (310 ml) cornflakes
2 tbsp milk powder
2 1/4 tsp sugar
1 tsp. kosher salt
2 tbsp + 1 tsp (1.25 oz / 35g) butter, melted

Make the Chocolate crumbs:

  1. Preheat oven to 300 degrees F (150 degrees C). Combine the flour, cornstarch, sugar, cocoa powder, and salt in the bowl of a stand mixer fitted with the paddle attachment and paddle on low speed until mixed.
  2. Add the butter and paddle on low speed until the mixture starts to come together in small clusters.
  3. Spread the clusters onto a lined cookie tray. Bake for 15-20 minutes, breaking them up occasionally. The crumbs should still be slightly moist to the touch at that point; they will dry and harden as they cool. Pour the cooled crumbs into a small bowl.
Make the cornflake crumbs:
  1. Turn oven down to 275 degrees F (140 degrees C)
  2. In a medium bowl, with your hands, crush cornflakes to ¼ of their original size. Add milk powder, sugar, and salt; toss to mix. Add butter; toss to coat.
  3. On the parchment lined cookie tray, spread clusters and bake for 15-20 minutes, at which point they should look toasted, smell buttery, and crunch gently when cooled slightly and chewed. Pour the cooled cornflake crumbs into the small bowl with the chocolate crumbs.
Combine the butter, sugar, and glucose in the bowl of a stand mixer fitted with the paddle attachment and cream together on medium-high for 2 to 3 minutes. Scrape down the sides of the bowl, add the egg, vanilla, and melted chocolate, and beat for 7 to 8 minutes.

Reduce the mixer speed to low and add the flour, cocoa powder, baking powder, baking soda, and salt. Mix just until the dough comes together, no longer than 1 minute. (Do not walk away from the machine during this step, or you will risk overmixing the dough.) Scrape down the sides of the bowl with a spatula.

Pour the chocolate chips, chocolate crumbs and cornflake crumbs into the bowl of the stand mixer. Still on low speed, mix just until incorporated, about 30 seconds.

Take 2-3 tbsp of dough and roll into a ball. Place balls of cookie dough on a parchment-lined cookie tray. Pat the tops of the cookie dough domes flat. Wrap the sheet pan tightly in plastic wrap and refrigerate for at least 1 hour, or up to 1 week.

Heat the oven to 375 degrees F (190 degrees C).

Arrange the chilled dough a minimum of 4 inches apart on parchment- or Silpat-lined sheet pans. Bake for 7-9 minutes. The cookies will puff, crackle, and spread. If after 9 minutes, the cookies still seem doughy in the center, give them another 1 minute in the oven, but not more. Let the cookies cool on the cookie tray for 5 minutes, before transferring to a wire rack to cool completely. Store in an airtight container for up to 5 days. The cookies are best served warm.

I’ve been putting off making the Momofuku recipes since my mixer is broken and my hand and whisk are no substitute for the 8 minutes of mixing these recipes call for. This one sounds incredible, and I’m bookmarking it to make when my mixer is fixed!

Haha, yes I think 8 minutes of mixing by hand would be a bit too intense! This was the first momofuku recipe I’ve made and it was worth it!

I just saw you on Foodgawker and I just posted a Christina Tosi inspired recipe and last week posted another.

These cookies sound great! Can’t go wrong with all those goodies in them!

Well I do know someone who really loves chocolates and can’t stop eating them until the last bite. But as for me, I do like chocolates (especially dark chocolates). Great recipe. This is the first time I’ve seen your blog but you amaze with this treat! Thanks for sharing such wonderful recipe. It makes baking such an easy tasks for all of us readers.

Hi Izy,
Okay, these are by far the best tasting cookies I have ever had in my life!
They are everything I love in a cookie: super chocolatey, soft-chewy, sweet-salty, with delightful crisp buttery-notes from the cornflakes.
A cookie can’t get any better than this. It just can’t. I would even say that it’s the world’s best cookie.
Anyway, THANK YOU for such an incredible recipe that is my family’s new favorite.
Did you take elements from Momofuku’s cookies and create these yourself?

Simply amazing!! I love you! :D
