Step 1 In the bowl of a stand mixer, or in a large bowl using a hand mixer, beat together the cream cheese and butter until well-blended. Slowly beat in the flour until well combined to form a soft dough. Divide the dough in half and shape each half into a disk. Wrap each disk in wax paper and chill for at least 1 hour, up to overnight.
Step 2 Heat the oven to 400 degrees. On a lightly floured surface, roll out each ball to about a 9-inch circle. Cut each circle into 12 wedges. Put a scant half teaspoon of jam on the wide end of each wedge. Roll each wedge from the wide end toward the point to form a crescent. Place each crescent point-side down on a parchment-lined cookie sheet and bake until golden brown, 10 to 15 minutes. Remove the cookies and cool on a rack.
