In the bowl of a stand mixer, combine 1½ cups (188 grams) flour and salt. Using the paddle attachment, add cold butter, 1 cube at a time, and beat at low speed for 3 seconds after each addition.

In a small bowl, combine everything bagel seasoning and remaining 1 cup (125 grams) flour. Add seasoning mixture, 1 tablespoon at a time, to butter mixture, beating until butter is pea-size. Add ¼ cup (60 grams) ice water, 1 tablespoon (15 grams) at a time, beating until a shaggy dough forms.

Turn out dough onto a clean surface, and knead 3 to 4 times. Shape into a 7-inch disk, and wrap in plastic wrap. Refrigerate for 1 hour or up to overnight.
