In a small bowl, beat together the powdered sugar and cream cheese. Separate the dough into 8 triangles. Spoon 1-teaspoon cream cheese and 1/2 teaspoon pumpkin butter onto the short straight edge of each triangle. Loosely roll up the crescent, starting at the short side and moving towards the opposite point. Place rolls point-side down onto the prepared baking sheet, then curve into a crescent shape. Repeat with remaining crescents.
