Preheat the oven to 375 F (190 C), line baking sheets with parchment paper.
Divide dough into 4 equal balls. Generously sprinkle clean work surface with corn starch. Roll one dough ball into a long, thin, and narrow strip – about 4″ x 12″. Trim to square up / tidy the edges.
Stir cooled fig mixture to incorporate any condensation that has developed. Transfer about one quarter of the filling to a pastry bag, or heavyweight plastic bag with a corner cut off – either way, you’ll want about ½″ diameter opening.
Pipe a long, fat line of filling up the center of the rolled dough, using up all of the filling in the bag. Use a clean spoon to gently spread the filling to a width of slightly more than 1″.
Gently fold one long side of dough over the filling. Fold the other long side over that, forming a long tube of filled cookie. Gently flip over, slice into cookies (About 1.5″ long pieces), and gently transfer to prepared baking sheet. Repeat with remaining dough and filling.
Bake for 12-15 minutes, or until edges are just starting to turn golden brown. Do not over bake!
Remove cookies from baking sheet, immediately cover with plastic wrap or – as we do – a long cake pan. Allow to steam/cool like this for at least 30 minutes. While these CAN be eaten right away, it’s best to let them sit overnight to let the moisture levels of the filling / cookie balance out a bit.
