Kolaches (sweet czech pastries)

To make the dough, grease a large bowl with cooking spray, set aside. Mix the milk, sugar, butter, vanilla, and egg yoke together in a large measuring cup. Stir the flour, yeast, and salt in the bowl of a stand mixer fitted with the dough hook. With the mixer on low, add the milk mixture. After the dough comes together, mix until shiny and smooth, about 5-7 minutes. Turn the dough out onto a heavy floured surface and shape into a ball. Place in greased bowl, cover with plastic wrap and let rest in warm place until doubled in size, about 1 hour. Spray 2 nine (9) inch cake pans with cooking spray. On a lighly floured surface, roll out the dough to a 12 inch circle, about 1/4 inch thick. Cut with 2" round cutter or larger and arrange in the pans with 2 in the center and 8 around the perimeter of each pan. Cover with plastic and let rise until doubled in size, about 45 minutes.
When ready to bake make an indentation with your finger and put the cream cheese and then the preserves. About 1 tsp each. Bake until golden brown. 15-20 minutes
