Mix cream cheese and 1/2 cup butter. Add flour until fully incorporated and form into a ball; divide and set one ball aside, covered lightly at room temperature while making filling and wrap the other in plastic and chill.

Place flour and butter into mixing bowl and pulse for 2 seconds on Turbo 2-3 times until mealy. Place cream cheese into mixing bowl and pulse for 2 seconds on Turbo 2-3 times until ingredients begin to form into a ball. Remove ingredients from mixing bowl to another bowl or place on the counter and form into 2 balls by hand; wrap one in plastic and chill and set the other aside, covered lightly at room temperature while making filling.

Melt 2 tablespoons of butter in a large skillet; add mushrooms, onion, thyme, salt and pepper. Saute, stirring constantly, until tender (about 5 minutes). Sprinkle flour over ingredients to avoid lumps; stir to thicken. Reduce heat to low; stir in sour cream. Heat just until thickened; remove from heat. Mixture should not be runny: it should sit in a mound on the pastry without spreading.

On a lightly floured surface, roll dough to less than 1/4 inch thickness; cut into 2.5 inch rounds with fluted cutter. Place small amount of filling in the middle of each circle (a heaping teaspoon); dot water along inside edge of each pastry circle to seal. Fold dough over filling to form a half-circle; press to seal dampened edges. Place on cookie sheet lined with parchment paper; press edges with a fork and puncture each decoratively to release steam while cooking OR recut sealed edges with the cutter, as illustrated.
