How to cut pinwheel cookies?
Make sure the cookie dough roll is well chilled (for at least an hour). Then remove it from the fridge, leave it for a minute and use a sharp knife to slice in 1/4-1/2-inch slices. If the dough is still soft, return it to the fridge (or freeze for a few minutes). If it’s too firm, allow it to warm up at room temperature for a few minutes.
