Please note that the heart cake cutouts filling the center of the cake roll, is a little too fluffy to work with, which I was ok with. But if you prefer, you could substitute a denser cake recipe like pound cake or this red velvet cake, for a sturdier finish. In that case, you could either make another cake roll using the other half of the cake mix, or 1 extra large cake roll or save it for later use. The cake roll is a perfect, all purpose recipe that could be used in different ways. For a change, forgo the cake filling and add fruits or make into a classic Yule Log. This recipe is designed for a 15.25oz box cake mix; other ingredients' quantities will have to be altered accordingly if using a different box mix size.
