In a food processor, add flour, Old Bay and salt and blend. Add butter and pulse until the dough forms clumps. Add cheese and crushed pretzels and use quick pulses to blend.

Turn dough onto work surface and knead it together. Divide into two equal portions and form into two 9 inch logs. Wrap in plastic wrap and refrigerate for at least an hour.

Preheat oven to 350º and line baking sheet with parchment paper.

Slice logs into ½ inch slices and place on prepared pan.

Bake for 19-21 minutes, rotate pan ½ way through. They should be golden across the top and firm. Allow to rest on a rack for 5 minutes and then transfer to a rack to cool completely.
