Compost Cookies

Compost may not sound quite appealing, but if you happen to like chocolate, coconut, and rich cookies diverse in texture and flavor with every bite, then please continue. Do I have your attention now? Based on Momfuku Milk Bar’s recipe, Christina Tosi calls for an assortment of non-conventional ingredients such as potato chips, ground coffee and pretzels. However, she advocates that in the true spirit of composting, use what you have. Or in my case, use what you like.

Some may saw ewww, but I absolutely love the addition of potato chips in Tosi’s recipe. They add a fantastic crunch, while the salt balances out the sweet. A decadent sweet and salty combo. For mine, I decided to go a bit on the less salty side, so I could control the salt amount. I opted for cornflakes, which still maintains that great crunch. When the cookie comes all together with walnut chunks, oats, chocolate and cornflakes, the flavors and textures keep it deliciously interesting.

This is a incredibly fun and versatile recipe I highly recommend. Give me a chewy and chunky cookie over a smooth, homogeneous one any day.
