Heat oven to 400℉ degrees. Line a baking sheet with parchment paper and set aside. Mix the brown sugar, cinnamon and regular sugar together in a plate.
In the bowl of a stand mixer, cream 4 tbsp of sugar and cream cheese. For ease of spreading, put the mixture in a piping bag fitted with a large tip. Set aside.
On a floured surface using, roll out puff pastry a making a rectangular sheet of about 12 x 10 inches.
Cut the sheet lengthwise, so that you have two long 12 x 5 inch sheets.
Pipe out the cream cheese horizontally across the length of one sheet, sprinkle walnuts and then begin to roll up the sheet lengthwise. Make sure that the seem is on the bottom.
Cut the role into 6 even bundles using a knife or pastry cutter.
Melt the butter and brush the butter on each bundle, then place each bundle in the sugar mixture to coat.
Transfer to the baking sheet. Repeat until you have made 12 bundles or so. Bake for about 20 to 25 minutes, keeping an eye that they do not burn. Make sure the bundles are sitting on their seem, otherwise they will puff out like crazy.
As soon as you take them out, dip them again in the sugar mixture and place them on a serving plate.

Top Tips
Work quickly with raw puff pastry dough as you want it to still be cool when you place it in the oven.If the cheese leeks out during cooking, just use a knife to push it back in to the pastry once you have taken in out of the oven.
