Soft and Fluffy Kolaches with a Thin Crust

Ingredients

• 4 cups bread flour (I used King Arthur)
• 4 teaspoons butter melted
• 8 tablespoons butter salted
• 8 oz cream cheese softened
• 1  egg yolk room temperature
• 2 large eggs at room temperature
• 2.5 tablespoons flour fine
• 0.5 cup granulated sugar 
• 1 pinch lemon zest 
• 1 teaspoon salt 
• 1 cup cream sour warmed
• 0.3 cup sugar 
• 0.5 teaspoon vanilla 
• 0.5 cup milk whole
• 1 packet yeast red
• 0.1  cinnamon 

Equipment

• bowl
• baking sheet
• sauce pan
• oven
• plastic wrap
• stand mixer
• microwave

Directions

1. Soften the butter in the microwave or in a saucepan so that it’s not cold, then add the milk and heat them both together until the milk starts to boil and the butter melts. I did this in a Pyrex 2 cup measure in the microwave, but a saucepan is fine.
2. Let mixture cool down to 130 degrees F.Meanwhile, combine 2 cups (252 grams) of the flour, sugar, yeast and salt in the bowl of a stand mixer.
3. Pour the butter mixture into the flour mixture, then add the warm sour cream and eggs and stir until well mixed.
4. Add the remaining flour by 1/2 cups until the dough is soft, but still a bit sticky. If you weighed the flour, most likely you will use it all. Don’t be tempted to add more, the dough should be a little sticky.Using the dough hook attachment, knead until dough is soft and elastic — though it does get smooth, it’s still a little sticky (though elastic) and you have to kind of scrape it it off the side of the bowl.
5. Transfer to another bowl that you’ve rubbed liberally with butter. At this point you can let the dough rise for an hour and proceed with the recipe, or you can refrigerate the dough overnight and let it rise slowly. It will not rise very much if you refrigerator it.Next day (or in an hour, after dough has risen), remove the dough from the refrigerator or wherever you’d set it to rise and punch it down. Divide it into about 20 pieces. Alternatively, you can roll it out into a rectangle and cut it into square pieces.
6. Place the pieces on lightly greased or parchment-lined baking sheets or 9×13 inch pans, leaving about an inch between them.
7. Brush with melted butter or whatever fat you prefer. Cover with a greased sheet of plastic wrap and let sit for about an hour or until they’ve risen. Note: If you are working with chilled dough, it may take the shaped rolls up to two hours to really rise.Make filling while dough rises. For the topping, just mix dry ingredients together and toss with butter until crumbly. For cheese, just beat cream cheese and sugar until smooth, then beat in yolk, zest and vanilla.Press a small indentation in the center of each roll and add a spoonful of cheese filling or canned pie filling.
8. Brush with a little more butter and sprinkle with crumb mixture.
9. Let sit while oven preheats to 350F
10. Bake in a 350 degree oven for about 18 to 20 minutes or until very lightly browned.
11. Serve the fruity ones hot, but let the cheese ones cool down a bit.
