In a small bowl, mix your softened cream cheese, pumpkin, powdered sugar, cinnamon, vanilla and pumpkin pie spice until creamy. Set aside.
On a non-sticking baking sheet, press each biscuit out into a rectangle form, about 4 inches by 3 inches, being careful not to break a hole in the dough. Spoon a heaping tablespoon of the filling into the center of each biscuit. Fold the long sides in, overlapping the edges, then fold the ends under, pressing the seams just very gently to help them seal. Turn the pastries over, placing them seam-side down.
Whisk an egg in a small bowl, then brush the tops of the pastries with egg wash. Sprinkle the tops with coarse sugar and cinnamon, if desired.
Bake at 375 degrees for 12 minutes. Serve immediately, or allow them to cool and refrigerate.
