I've been making this one for years... and lost my copy and found again on all recipes site... this one is not an overly sweet cookie as there is no sugar..except in the vanilla icecream and preserves.. but I have adapted it to add sugar free preserves and sugar free icecream and for my diabetic friends. these are especially good without the fruit filling .. bake and dust with powder sugar.. a nice light buttery cookie.. they do freeze well.. just make sure the are not touching each other as they will be sticky when thawing out..
Let your butter soften up ( not melted)then add to flour and crumble.. I put in the stand up mixer and use the whisk blade.. just until crumbled
Then add softened icecream and switch to your dough hook and mix well to create a smooth dough.. dough will be really chilly... form into a ball wrap with plastic wrap and refrige overnight
next day.. roll the dough about 1/8 to 1/4 inch and make small circle cutouts and gently make a thumbprint . don't use jelly or jam.. they will just get hot and runny and drip all over the place.. use preserves as it has more fruit ...
I like to leave my kolacky's round.. others may like them with sides folded toward center over fruit.. it's up to you
Bake at 350 for about 20 min.. let cool and dust with powder sugar
