Line baking sheets with parchment or Silpat mats and set aside.
Roll out dough into a 13” x 21” rectangle on a lightly floured surface.
Spread filling onto the rolled out dough rectangle with a silicone spatula or offset spatula so that it covers the entire area from edge to edge.
Mark 7" sections on the 21" side with the back of a knife so that you have three equal sections. Fold the left side to the middle, then fold the right side over the left side. Turn the dough so that the openings are on the left and right sides and roll out the dough slightly.
Using your ruler and a sharp knife or pastry wheel, cut 2 cm strands. You should have 15-20 strands.
Starting from the end, wrap one strand around the tips of your thumb and four fingers (three if you have big hands) twice, twisting slightly as you wrap, then slip your thumb out of the roll, loop the strand around one last time then tuck the end and your thumb loop into the bottom. If you're having trouble, please re-watch the GIF above. Repeat with all strands.
Place buns on your pre-lined baking sheets, (giving enough room for the dough to rise and spread during proofing and baking), cover with a kitchen towel and let rise for about 30 minutes.
While proofing, preheat oven to 435°F (at least 30 minutes before baking)
