Based on the sheer number of somewhat bizarre drying experiments I’ve been running around here lately, you might have caught on that I’m a new convert to the joys home dehydration. Beyond your basic fruit snacks and carrot chips, I’ve been particularly interested in manufacturing my own DIY vegetable powders–everything from your standard garlic and onion to your more exotic tomato and red pepper.

In the course of things, I ended up dehydrating a bag of frozen sweet corn for a recipe that never materialized, so I packed the dried kernels away in a mason jar until a good use for them presented itself.

A few weeks later, however, I caught Savory Simple’s post on Momofuku Milk Bar’s Corn Cookies and was immediately seduced by the quirky taste profile the recipe suggested. I was less attracted to sourcing the unusual ingredients required. Did I really want to special order corn powder? Hmm, might my dehydrated corn step in to save the day? I committed…to thinking about it.

And so the recipe went into my “to make one day” pile, and there it sat. For months. Finally, frustrated by my own inaction, I pulled out my “coffee grinder reserved for spices” and got to work. The dried sweet corn was powdered; lacking corn flour, I also blitzed some of my DIY cornmeal until the motor was near to overheating and my fingers were satisfied with the texture. I sifted for good measure. Twice.

Do these cookies match the originator‘s? I actually can’t say, since for as much time as I spend in New York City, I have yet to make a pilgrimage to the Milk Bar. Perhaps I shall pop in this month, now that I have a mission. What I can say is that I made these with just what was in my pantry, and they were fantastic. The freshly powdered dehydrated sweet corn and corn flour provided a strong corn flavor that made for a particularly unique treat.

NOTES: Before baking these, I read a recommendation to substitute bread flour for the AP to help the cookies stand up to the high butter content, controlling spreading while maintaining a chewy rather than crisp texture. It was suggested that King Arthur bread flour was what they use at the Milk Bar, and I liked the results I got this way (though I did not bake a comparison batch).

On baking day, it was cold enough in my house, and I was impatient enough to get started, that getting my butter to room temperature seemed like a battle I was destined to lose. However, I remembered a neat trick I learned (via Food in Jars) to soften butter in warm tap water. Killer kitchen tip for the poor planners in the crowd like myself!

1 1/3 cups (225 g) King Arthur bread flour
1/4 cup (45 g) corn flour (I ground cornmeal to a super fine level; for international readers, this is NOT corn starch)
2/3 cup (65 g) freeze-dried corn powder (I used finely ground dehydrated sweet corn kernels)
3/4 teaspoon baking powder
1/4 teaspoon baking soda
1 1/2 teaspoons kosher salt
16 tablespoons (225 g) butter, at room temperature
1 1/2 cups (300 g) sugar
1 egg

Measure dry ingredients into a mixing bowl and whisk to evenly incorporate. Set aside.

Cream butter and sugar together (medium-high for 2 to 3 minutes). Scrape down bowl, add egg, and beat for 7 minutes more.

Reduce speed to low and add dry ingredients to wet. Mix just until combined.

Portion into 15 rounds on a parchment-lined baking sheet. Flatten each cookie to about an inch thick. Cover with plastic wrap and refrigerate for at least one hour before baking–do not skip this step! Cookies baked several days later, however, were just as good.

When ready to bake, heat oven to 350°F.

Place six raw dough pucks spaced well apart on a parchment-lined cookie sheet (they will spread considerably). Bake 16 minutes, until edged have lightly browned. Allow cookies to cool and firm up before removing from pan. Store in an air-tight container.
