Cut-Out Sugar Cookies

Cream together butter and sugar.

Beat in egg.

Add vanilla, salt, and flour. Mix until just incorporated.

Wrap air-tight in cling wrap. Refrigerate until firm, about 1 hour.

Roll to 1/4 inch thick, cut shapes, and freeze until stiff and completely unbendable. Like you could stand it up on an edge and there'd be zero flop, and it you tried too hard to bend it the cookie would snap. It takes a couple hours to freeze thoroughly.

Bake at 325 degrees F for 10-25 minutes, until edges are very slightly golden.
