12. Assemble the Swiss Roll
Unroll the cake on a clean, flat work surface. Remove the top piece of parchment paper. The brown side will be facing up. Using an offset spatula or the back of a spoon, spread the cooled cranberry jam evenly over the cake, from edge to edge. Next add the cream cheese mixture and again spread the filling from edge to edge, covering the cranberry jam. Roll the cake into a tight log, again starting from one of the shorter edges. As you lift and roll the cake, make sure to pull back the bottom piece of parchment so as not to roll it into the center of the cake. Place the cake seam-side down on a tray, cover with plastic wrap, and place in the fridge for 1 to 3 hours to allow the filling to set before slicing. When ready to serve, dust the top with powdered sugar.
