1)Feel free to make the balls as small or as large as you would like. Make sure to adjust the bake time accordingly. 2) You may use as little or as much chocolate between the cookie layers. Make sure you allow the chocolate to melt completely before you try to move them too much. 3) Once you have covered them in powdered sugar it is hard to move them without leaving finger prints all over the cookies. I found it is best to use small tongs, chopsticks or even large tweezers. 4) Not all powdered sugar is vegan. Make sure your powdered sugar is!
