On a sheet lined with parchment or plastic wrap, portion out eight tablespoon-sized scoops of lemon curd. Flatten them evenly to about 1/4 inch thick and freeze for an hour or two until they're firm.

Space the cookies out on the parchment-lined pan and bake for 12-13 minutes. Allow to cool completely on the baking sheet afterward. They'll seem soft but will firm up as they sit.
