Scrape bowl down and add flour while beating on low. Scrape bowl once more and mix until combined. Shape the dough into a rectangular prism, wrap in plastic and chill until firm, at least an hour. Preheat oven to 350 degrees. Use a sharp knife to cut 1/2-inch thick slices. Place slices, spaced at least an inch apart onto a baking sheet lined with a silicone mat or parchment paper. Use a fork or skewer to indent a pattern onto the top. Bake for about 10 minutes, rotating baking sheet in the oven halfway through.
