Every Christmas, we would make cookie trays for friends and family.  The one required cookie was Kringla.  These are sweet, cakey cookies that go really well with tea or coffee.  I make them every year because they are the one cookie that the boys request!  The recipe came from an Iowa Church cookbook and, while they can be a bit pesky to shape, they are a real treat – especially if lightly warmed in a toaster oven.  I find it easier to cream the butter with the sugar and let the sour cream come to room temperature, but it is imperative that the dough be chilled!
