1 cup all-purpose flour (5 ounces)
1 cup toasted and husked hazelnuts (5 ounces)
¼ cup cornstarch
½ teaspoon kosher salt
½ cup unsalted butter, at room temperature
½ cup sugar (3 ½ ounces)
1 teaspoon ground cardamom
1 teaspoon pure vanilla extract
4 ounces dark chocolate chips
¼ cup toasted and husked hazelnuts, chopped
Process flour, hazelnuts, cornstarch, and salt in a food processor until hazelnuts are finely ground, about 40 seconds, stopping to stir halfway through.
Using stand mixer fitted with paddle, beat butter and sugar at medium speed until light and fluffy, about 2 minutes. Scrape down sides of bowl, add cardamom and vanilla and mix to combine.
Add flour-hazelnut mixture and beat on medium until dough resembles damp sand and holds together when pressed between fingers, 3-4 minutes. (Make sure to mix for at least 3 minutes for best results.)
Turn dough out onto a sheet of plastic wrap and firmly press together to form a 7×3-inch rectangle. Tightly wrap with plastic and refrigerate for 2 hours or up to 3 days.
Preheat oven to 325° and line baking sheet with parchment paper.
Slice chilled dough into ¼-inch thick slices and transfer to prepared baking sheet, spacing 1 inch apart. Bake 18-20 minutes, rotating pan halfway through, until edges begin to brown. Cool cookies on sheet pan 5 minutes, then transfer to wire rack to cool completely.
In a glass bowl, melt chocolate chips in microwave on high in 20 second intervals, stirring after each interval, until completely melted.
Dip cookies in chocolate, transfer to wire racks, and sprinkle with chopped hazelnuts. Once chocolate has set, store cookies in an airtight container with parchment paper between each layer.
So you might be reading over the recipe thinking, “uhmm hello, these cookies have to chill for two hours, how is this a weeknight-friendly recipe?” Well you see, if you whip up this dough the night before (or even a few night before) all you have to do is slice, bake, and dunk when you are ready. Heck, you could whip up the dough in the morning before work. But who am I kidding, who wants to start off the day with 3 spoonfuls of cookie dough for breakfast?…
