Prepare the Yeast Mixture:In a small bowl, dissolve the dry yeast in warm milk. Let it sit for about 5 minutes, or until it becomes foamy.
Make the Dough:In a large mixing bowl, combine the all-purpose flour, sugar, and salt. Add the eggs, melted butter, and the yeast mixture. Stir the ingredients together until a dough forms.
Knead the Dough:Turn the dough onto a floured surface and knead for about 8-10 minutes, or until the dough is smooth and elastic.
Let the Dough Rise:Place the kneaded dough in a greased bowl and cover it with a kitchen towel. Allow the dough to rise for 1 hour 30 minutes, or until it doubles in size.
Preheat the Oven:Preheat your oven to 350°F (175°C) while the dough is rising.
Roll Out the Dough:Once the dough has risen, turn it onto a floured surface and roll it out to about 1/4 inch thick
Add the Filling:Spread your chosen filling (fruit preserves, poppy seed paste, or sweetened cream cheese) evenly over the rolled-out dough.
Shape the Kolacz:Carefully fold or shape the dough into a ring or roll, depending on your preference, and place it onto a baking sheet lined with parchment paper.
Bake the Kolacz:Place the baking sheet in the preheated oven and bake for about 25 minutes, or until the Kolacz turns golden brown.
Glaze the Kolacz (Optional):After removing the Kolacz from the oven and letting it cool slightly, brush with powdered sugar for a sweet glaze if desired.
Serve and Enjoy:Allow the Kolacz to cool completely before serving. Enjoy your delicious homemade Kolacz!
