Make sure to drain as much liquid from fig puree as possible. If using preserves, skip this step.
In a large bowl, cream together butter and brown sugar until light and fluffy. About 3 minutes.
Add baking soda, salt, cinnamon, honey, and orange zest. Beat until light and fluffy again; another 3 minutes.
Add egg yolks one at a time. Beating between each addition.
Sprinkle in flour, folding gently, until well combined.
Form dough into a disc as you would pie crust. Wrap in plastic wrap and refrigerate at least 1 hour and up to 1 week. Allow dough to sit out 30 minutes before use.
If using fresh puree, add sweetener and cinnamon. Be sure to give it a taste! Once it's to your liking, scoop filling into the quart storage bag and set aside.
Preheat oven to 350 degree F
If dough is still too chilly, knead it gently until it is pliable.
Dust silicone mat or parchment covered work surface with flour and roll dough into an 8" square.
Sprinkle both sides of dough with flour and continue to roll into a 8"x15" rectangle.
Brush off excess flour and cut into 3" thick strips with a pizza cutter on the short side; 8" long strips, 3" wide.
Cut one corner of the fig-filled bag until the opening is about 1/2" long.
Evenly pipe filling down the enter of each strip.
Using the bench scraper to help fold over each side of the strips, over top of the filling. **If dough has become to warm, place in freezer for 15 minutes.
Carefully, still using the bench scraper, roll each folded strip over; seam-side down. Press down slightly, flattening each strip to get that iconic shape.
Transfer long fig bars, do not cut yet, along with silicone mat or parchment onto baking sheet.
Bake for 15-18 minutes.
Directly after pulling bars from oven, use bench scraper to slice bars into 1" pieces.
Transfer into a air-tight container. Place a piece of wax paper between layers. DO NOT overlap bars directly onto each other, they will stick together and tear when pulled apart.
Tightly secure lid and let sit on the counter for at least 6 hours before eating. This allows them to become very moist and chewy.
After 48 hours, place in the fridge. Will last up to 1 month in the fridge or 6 months in the freezer.
