In a medium bowl, add butter, brown sugar, orange zest and cinnamon. Use a fork to mash mixture into a paste. I highly suggest making sure your butter is room temperature soft so its easier to mash
Prepare a work surface with flour and unroll one of the crescent dough cans. Press perforations closed to make a single rectangle (be gentle with the dough). Spread half of the butter mixture evenly on crescent dough. Scatter walnuts on top of butter mixture.
Start rolling the dough from the long side until you make a log. Then cut crosswise into six pieces. Repeat with second can of dough and butter mixture.
Once you have your 12 pieces of rolls, place cut side up in an 8-inch cake pan.
Bake until a deep golden brown. Takes about 30-35 minutes
