Cream Cheese Kolache

Kolache Dough
2 Add the yeast, 1 teaspoon sugar, and ginger to the ¼ cup milk and set aside.
4 Put the 1/2 cup milk and butter in a microwave-safe bowl and heat until the butter melts.
6 Let cool to 110F.
8 It should feel comfortably warm to when you drop a few drops on your wrist.
10 In the bowl of a stand mixer fitted with a paddle attachment combine 2 cups of the flour with the salt, sugar, and potato flakes.
12 Add the yeast mixture and the cooled milk mixture and stir until blended.
14 Add the egg and blend it in.
16 Add another 1/3 cup of flour. The dough will be sticky.
18 Switch to the dough hook.
20 Add flour a tablespoon or two at a time until the dough doesn’t stick to the sides of the bowl.

26 Remove from the mixer bowl and form into a ball.
28 Rub the ball with melted butter then place it in a greased bowl.
30 Turn the ball over once.
32 Cover the bowl loosely with a clean tea towel.
34 Let it rise for 1 hour 15 minutes, or until doubled in bulk.
36 Punch down.
38 Divide the dough into 12 pieces about the size of an egg.
40 Roll into balls and arrange them 2 inches apart on a baking sheet lined with parchment.
