Rolling a sponge cake requires immediate action the moment it leaves the oven. Invert the hot 15.5-by-10.5-inch jelly roll pan directly onto a towel dusted with powdered sugar before the crumb cools and loses its elasticity. Peel away the wax paper carefully to avoid tearing the delicate surface. Roll the warm cake and towel together immediately from the narrow end to train the crumb into a spiral shape, then let it rest seam-side down on a wire rack until completely cool. Whipped cream and cocoa filling goes inside only after this thermal memory is set, preventing cracks. Scaling this recipe up requires baking multiple pans separately rather than overcrowding the oven, because a thicker batter will not bake evenly in the required fifteen minutes at 400 degrees Fahrenheit. Once filled and re-rolled without the towel, coat the exterior in chocolate buttercream. Score the frosting with the tines of a fork to mimic bark texture, and anchor a cut-off end section to the side with extra icing to create a realistic branch stump. Finish decorating with halved candied spearmint leaves and red cinnamon candies arranged to resemble holly.
