I've always used a brown dish towel reserved for rolling my chocolate and yellow cake rolls, especially because it doesn't show the stains that are near impossible to remove even when washing it in the clothes washer. Recently I received a new device designed specifically for use with cake rolls and after trying it out on a chocolate biscuit found that not only did it worked perfectly, it wiped totally clean with a sponge and dish detergent. Although the instructions suggest using 1/4 cup of powdered sugar, I used my usual light dusting of cocoa (8 grams/a little under 2 tablespoons) and there was absolutely no sticking. It works best to set the edge of the cake near the edge of the liner, because when rolling the cake tends to move forward. With either the towel or cake roller, the cake needs to cool completely on a rack. To keep the cake roller from unrolling I set it seam-side-down on the rack and placed a metal bar on either side. Any long object such as a ruler will work. The Easy Cake Roller keeps the cake moist and, of course, is reusable. You can purchase it on the company's website.
