1 cup unsalted butter, melted and cooled
2 teaspoons pure vanilla extract
1 cup sugar
1 teaspoon salt
2 cups all-purpose flour
1 cup unsalted roasted cashews
1 cup bittersweet chocolate chips (60% cacao--I like Ghiradelli)
Preheat the oven to 350 degrees and set a rack to the center position. Pour the melted butter into a large bowl, and stir in the vanilla. With a wooden spoon (or your hands, if your prefer), add the sugar, salt and flour and mix to combine--the mixture will be somewhat crumbly, like a moist pie dough. Stir in the nuts and chocolate chips. Press the mixture in a thin, even layer onto an ungreased cookie sheet (use the chocolate chips as your guide--try to get them in as close to a single layer as possible throughout the dough, and you'll have the right thickness). You may not fill the entire sheet with the dough--that's okay.
Bake for 23-25 minutes, until light golden brown (the edges will be a bit darker than the center). Let cool completely before breaking into whatever sized pieces you desire. Store in an airtight container at room temperature.
