For the rolls: Preheat the oven to 350 degrees F.
On a lightly floured flat surface, roll out the dough and separate it into 4 rectangular parts, leaving 2 triangles attached for each of the 4 sections. Each section should appear to be a rectangle with a perforated dividing line through its center diagonally. Carefully pinch together the 2 triangles along this line to close the gaps and seal it to make it 1 piece. Cut each piece in half to make 2 squares. Repeat for each and place on a nonstick baking sheet with sides. There should be 8 squares to fill.
Combine the candy bars and bacon in a medium bowl. Add 1 heaping tablespoon of the candy mixture in a row along the length of the prepared dough in the center, leaving enough room to pull the uncovered dough on the edges up and over the pile of filling.
For the topping: In a small bowl, mix the sour cream and just enough water to make it loose like glue, yes glue. Brush this over the top of each roll and sprinkle with sugar and a pinch of flake salt.
Bake until golden on top, 16 to 20 minutes. Allow to cool slightly.
