Compost Cookies

Compost Cookies

A long time ago when I was just a little Katie, I dreamt of a cookie. It was part chocolate chip, part honeycomb, part candy and part pretzel and potato chip. I was a weird kid. Ask my parents – I once invented something called Banana Croak Pie, a masterpiece I never actually got around to CREATING.

Anyway, imagine my surprise when one day, not long ago, I came across a reference in a book about something called a Compost Cookie. It includes pretty much the contents of your kitchen junk food cupboard, INCLUDING, but not at all limited to COFFEE GROUNDS!

Invented at the Momofuku Milk Bar in NYC, I have read only RAVE reviews of this amazing biscuit… though I have yet to sample it for myself.

But in the spirit of trying something new, I went ahead and created my own easy, fast and highly experimental Compost Cookie recipe.

Yield: 16 cookies
Prep Time: 40 minutes
Cook Time: 15 minutes
Additional Time: 1 hour
Total Time: 1 hour 55 minutes

This incredible copycat recipe comes from the Momofuku Milk Bar in NYC. It's got everything but the kitchen sink!

Ingredients

Compost Cookies

  • 16 tbsp unsalted butter at room temperature
  • 1 C granulated sugar
  • ⅔ C tightly packed light brown sugar
  • 1 tbsp light corn syrup
  • 1 large egg
  • ½ tsp pure vanilla extract
  • 1 ⅓ C all-purpose flour
  • ½ tsp baking powder
  • ¼ tsp baking soda
  • 1 tsp kosher salt
  • ½ C butterscotch chips
  • ¾ C chocolate chips
  • ⅓ C old-fashioned rolled oats (not instant oats)
  • 2 ½ teaspoons ground coffee (not instant coffee)
  • 2 C salted potato chips
  • 1 C mini pretzels

Graham Cracker Crust

  • 6 tbsp graham cracker crumbs
  • 1 tbsp milk powder
  • 1 ½ tsp granulated sugar
  • ¼ tsp kosher salt
  • 1 tbsp unsalted butter melted
  • 1 tbsp heavy cream

Instructions

Graham Cracker Crust:

  1. Place the graham cracker crumbs, sugar, milk powder and salt in a medium bowl and gently stir to combine.
  2. In a separate bowl, whisk together the butter and heavy cream.
  3. Add the wet ingredients to the dry ingredients, then mix together until well combined. The mixture should hold it's shape if pinched together in the palm of your hand.
  4. If necessary, add a small amount of additional melted butter.
  5. Set aside.

Compost Cookies:

  1. In the bowl of a stand mixer fitted with a paddle attachment, combine the butter, sugars and corn syrup and cream together on medium high for 2-3 minutes.
  2. After scraping down the sides of the bowl, add in the egg and vanilla, then beat for an additional 7-8 minutes.
  3. Reduce the speed to low, then add in the flour, baking powder, baking soda and salt, mixing until the dough just comes together, around one minute. Don't overmix.
  4. Scrape down the sides of the bowl with a rubber spatula.
  5. Once again on low speed, add in the chocolate chips, butterscotch chips, oats, coffee and graham cracker crust mixture until just incorporated, about 30 seconds. Then add the potato chips and pretzels, mixing until barely incorporated.
  6. Using a ⅓ cup measure or an ice cream scoop, portion out the dough onto a parchment-lined sheet pan. Pat the top of the cookies flat.
  7. Wrap the sheet pan with plastic wrap and refrigerate for at least an hour and up to a week. Do not bake from room temperature.
  8. When ready to bake, heat the over to 375°F.
  9. Arrange the cold dough at least 4 inches apart on parchement or silpat lined sheet pans and bake for 15 minutes. Cookies should puff up, crack and spread. They will lightly brown on the edges.
  10. Cool cookies completely on the sheet pans before transferring to an airtight container for storage.
  11. They will keep for one week at room temperatore, or they will keep for a month in the freezer.

Notes

This recipe is extremely loose, and you can really add anything that you fancy, sweet or savory. It’s highly forgiving…

Chocolate and Butterscotch Chips: You can use mini- chips if you prefer, and the Momofuku cookbook actually calls for mini chips.

Coffee Grounds: It is important NOT to use instant coffee, but regular ground coffee. I like using flavored coffee, but any type will do. Just use it before it is brewed, fresh from the package.

Rolled Oats: Use rolled oats, not instant oats.

Potato Chips: Any kind of plain salted chip will work, but a nice thick chip will work best. I like using Ruffles or Cape Cod.

Mini Pretzels: You can use regular pretzels chopped up if easier. Or even pretzel sticks work fine.

This recipe uses kosher salt, but if you are using table salt, make sure to use less as that is a saltier type of salt! Look up conversion rates if you need to.

If you decide to make smaller cookies, you will likely need to break up the pretzels and potato chips a bit more to do so. Also you should bake smaller cookies for less time.

To freeze:

You can freeze the cookie dough before baking by creating flat cookie dough rounds and freezing them inside a freezer bag. They will last 3 months in the freezer. When ready to bake, remove however many cookie dough circles as desired, thaw in the fridge, then bake as per recipe. You can also bake from frozen, but they won't spread as well and may need extra time.

The saltiness and texture of the savoury snacks make this quite a chewy, but not too sweet biscuit. I dread to think about the calorie count, but it really is a strangely exciting little cookie.

When I have a weekend free, I’m going to try the ACTUAL recipe from the link above, but for now, these strange little sweets are hitting the spot.
