In a large bowl blend margarine and cream cheese together, by hand with a metal spoon. Slowly add flour until it is all incorporated and a dough is formed. The dough will be soft and sticky. Cover the bowl with plastic wrap and put in refrigerator overnight, or for several hours (until hard to the touch).
Flour the countertop. Take a handful of dough out of bowl returning the unused portion to the refrigerator (continue this process until all mixture is used). Roll handful of dough out into an approximately 1/4-inch thickness. Take a 2 by 3-inch diamond shaped cookie cutter, and cut as many diamonds as possible (size of kolachky should be two bites, so the cutter cannot be large). Take leftover dough and roll out again, cutting more diamonds. Repeat until all the dough is used.
Place the diamond cut out onto the palm of hand. Put a 1/2 to 1 teaspoon of fruit filling (apricot or strawberry or raspberry or prune flavors) into the center of the diamond shape.
Dip your finger in a little bit of water, put on one side of diamond. Fold lengthwise and seal the tops of the kolachky together to create a 3-dimensional diamond shape. Place on cookie sheets and bake in a preheated 350 degree oven for 10 to12 minutes.
DO NOT USE Super heat cookie sheets or any of the new non-stick coated cookie sheets. They will bake too quickly and burn the bottoms of the kolachky before you realize it. YOU MUST USE ANY KIND OF CHEAP COOKIE SHEETS usually bought at a grocery store. Cover the cookie sheet with foil or parchment paper. Do not grease the foil.
Look at your kolachky every few minutes, while baking, as ovens vary in heat distribution. The later batches may cook faster than the first ones. Check the BOTTOMS of the kolachkys. They are done when the BOTTOMS are soft golden brown. The tops may not look done, but they ARE! Remove from oven, wait 3 minutes, then remove to a cooling rack. When ready to serve, sprinkle with powdered sugar.
