I just wanted to comment on these, as I haven't made them from this exact recipe but have been making them for years. Any recipe I have ever seen for Kolacky has always called for them to be dusted with powdered sugar after baking/cooling or just before serving. You will note that there is barely any sugar in this dough (In fact, my recipe has NO sugar at all in the dough), so the powdered sugar is really a necessity. Try it and you should have good results!
This was easy and quick..I let the dough refrigerate for 3 hours than pressed on cookie sheet and added peach preserves and also apricot. Not real sweet but a quick desert. I changed the serving size and I used margerine instead of butter. Next time, I'll use real butter. Overall, really good, thanks.
