preheat oven to 350℉
roll dough into balls of 19g, and roll pumpkin filling into balls of 24g. +/- 1g should be fine, you don't need to perfect with it.
place dough ball between two small pieces of parchment paper and flatten with fingers.
continue flattening until about 1mm thick, you'll want thickness to resemble a corn tortilla. you can use the bottom of a glass, a tortilla press, or your fingers.
carefully remove the dough wrapper from the parchment paper (it'll be fragile!) and place on palm of non-dominant hand (left hand for most people).
using your right hand, slowly pinch the dough wrapper around the filling ball, removing excess as you go. patch up the top with the extras at the end if needed.
place the wrapped dough and filling ball seam side down on a baking sheet lined with parchment paper.
make sure the ball is shaped in a way that your stamp mold can encompass it. cover the ball with your mold, and tamp down firmly but gently.
remove by pushing the completed mooncake through the stamp, and gently wiggling the mooncake out if needed.
repeat until you've used up all the filling balls!
