Ingredients
- 1 3/4 cups all-purpose flour
- 3/4 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1/2 cup unsalted butter, room temperature
- 1 cup light brown sugar
- 1/2 cup granulated sugar
- 1/3 cup white miso paste
- 1/4 cup chunky peanut butter
- 1 large egg
- 1 1/2 teaspoons vanilla extract
- 1/2 cup Demerara sugar, plus more as needed
Preparation
1. In a medium bowl, combine flour, baking soda, and baking powder and whisk until incorporated. Set aside.
2. In the bowl of a stand mixer fitted with the paddle attachment, mix butter, light brown sugar, and granulated sugar at medium speed until light and fluffy, about 5 minutes.
3. Add miso and peanut butter to the mixing bowl, and continue to mix at medium speed, about 1 minute. Scrape down sides of bowl and mix a bit more if needed. Add egg and vanilla and mix until just combined.
4. Add 1/3 flour mixture and mix on low until incorporated. Repeat with remaining flour mixture in two batches.
5. Place 1/2 cup Demerara sugar into a small bowl. Working with one piece at a time, scoop out about 2 heaping tablespoons of dough (50 grams), and roll between your hands until nice and round. (If dough is too soft to roll, pop mixing bowl in fridge for 5-10 minutes to firm up slightly.) Drop the piece of dough into bowl of Demerara sugar and turn to coat. Transfer to a parchment-lined baking sheet. Repeat with all the dough, arranging them about 3 inches apart.
6. Refrigerate 2 hours and up to overnight. (Even 15 minutes of refrigerator time will help dough firm up and flavors meld. The longer dough is refrigerated, the more mellow the flavors will be.)
7. When ready to bake, preheat oven to 350F. Bake cookies about 15 minutes, until crisp at edges and slightly puffed in middle. Cookies should be a bit underdone in the center. Pull out baking sheet and hit it against a counter. Place back in oven to finish for about 3-4 minutes. When cookies are firm at edges and slightly puffed in center, pull them out and again hit the baking sheet against the counter. The cookies should appear flat and crinkly at the center.
8. Let cool on baking sheet a few minutes and transfer to a cooling rack. Store fully cooled cookies in airtight container; they should retain their chewy texture for a few days.
