Just an FYI, these cookies involve 2 steps -- 3 if you include the difficult-to-delay-gratification waiting time of 1 hour to SEVEN days-- but they are SO worth it! The original recipe says it makes 12-17 cookies, but I got 20 (with just a little extra to make a mini tasting cookie ;-)).
Blueberry & Cream Cookies
Momofuku Milk Bar (you have to click on the link up top for the cookies...there's no direct link)
For the milk crumbs:
1/2 cup milk powder
1/4 cup flour
2 Tbsp cornstarch
2 Tbsp sugar
1/2 tsp kosher salt (I crust it between my fingers when I add it to the recipe)
4 Tbsp butter, melted
1/4 cup milk powder
3 oz white chocolate, melted
For the cookies:
16 Tbsp butter, at room temp
3/4 cup granulated sugar
2/3 cup light brown sugar
1/4 cup glucose (I didn't have any....I used light corn syrup and they were great!)
2 cup flur
1/2 tsp baking powder
1/4 tsp baking soda
1.5 tsp kosher salt (I like to crush it between my fingers as I add it in)
1/2 recipe milk crumbs
3/4 cup dried blueberries
Make the milk crumbs:
Preheat the oven to 250F.
Combine the 1/2 cup milk powder, flour, cornstarch, sugar, and salt in a medium bowl.
Toss with your hands to mix.
Add the melted butter and toss, using a spatula, until the mixture starts to come together and form small clusters.
Spread the clusters on a parchment- or silpat-lined sheet pan.
Bake for 20 minutes.
The crumbs should be sandy at that point, and the kitchen should smell like buttery heaven.
Cool the crumbs completely.
Crumble any crumbs that are bigger than 1/2 inch in diameter.
Put the crumbs in a medium bowl.
Add the 1/4 cup of milk powder.
Toss together until it is evenly distributed throughout the mixture.
Pour the white chocolate over the crumbs and toss until the clusters are enrobed.
The continue to toss them every 5 minutes until the white chocolate hardens and the clusters are no longer sticky.
Try not to eat them all.
[The crumbs will keep in an airtight container in the fridge or freezer for up to 1 month.]
Make the cookies:
Combine the butter, sugars, and glucose/corn syrup in the bowl of a stand mixer with the paddle attachment.
Cream on medium-high for 2-3 minutes.
Scrape down the sides of the bowl.
Add the eggs.
Beat for 7-8 minutes.
Reduce the mixer speed to low and add the flour, baking powder, baking soda, and salt.
Mix just until the dough comes together, no longer than 1 minute.
Scrap down the sides of the bowl with a spatula.
While still on low speed, add the milk crumbs and mix until they're incorporated, no more than 30 seconds.
Chase the milk crumbs with the dried blueberries, mixing them in for 30 seconds.
Using a 2 3/4 oz ice cream scoop (or a 1/3 cup measure), portion out the dough onto a parchment-lined sheet pan.
Pat the tops of the cookie 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 350F.
Arrange chilled dough a minimum of 4 inches apart on a parchment- or silpat-lined sheet pans.
Bake for 18 minutes (mine were ready after 15-16 minutes....watch them carefully).
The cookies will puff, crackle, and spread.
After 18 minutes they should be very faintly browned on the edges yet still bright yellow in the center.
Cool the cookies completely on the sheet pans before transferring them to a plate or to an airtight container for storage.
At room temp, the cookies will keep fresh for 5 days; in the freezer, they will keep for up to 1 month.
