Making kolaches is straightforward when you follow these easy steps:

1. Activate the Yeast: In a small bowl, combine the active dry yeast with ¼ cup of warm milk (110°F). Let it sit for about 5-10 minutes until frothy.
2. Mix Wet Ingredients: In a large mixing bowl, combine the remaining milk, softened butter, sugar, and eggs. Mix until well combined.
3. Add Yeast Mixture: Once the yeast is activated, add it to the wet ingredients and stir well.
4. Combine Flour and Salt: In another bowl, whisk together the flour and salt. Gradually add this flour mixture to the wet ingredients while stirring.
5. Knead the Dough: Transfer the dough to a floured surface and knead for about 5-7 minutes until it becomes smooth and elastic.
6. First Rise: Place the dough in a greased bowl, cover it with a cloth, and leave it in a warm place to rise for about 1 hour or until it doubles in size.
7. Preheat the Oven: During the last 15 minutes of rising, preheat your oven to 375°F (190°C).
8. Shape the Kolaches: Once the dough has risen, punch it down and turn it out onto a floured surface. Roll it out to about ½ inch thickness and cut out circles using a round cutter or glass.
9. Fill the Kolaches: Add about a tablespoon of your desired filling to the center of each circle. Fold the dough over or pinch the ends together, depending on your filling choice.
10. Second Rise: Place the filled kolaches on a greased baking sheet. Cover them with a cloth and allow them to rise for another 30 minutes.
11. Egg Wash: Beat the egg with a tablespoon of water and brush it over the tops of the kolaches for a beautiful golden finish.
12. Bake: Bake for about 20 minutes or until the kolaches are lightly golden brown.
13. Cool and Dust: Remove the kolaches from the oven and allow them to cool slightly. If desired, dust them with powdered sugar for a touch of sweetness.

By following these steps, you can create a batch of kolaches that are soft, fluffy, and incredibly delicious.
