Roll approx. 10g pieces of mochi into small balls. (15g if making it with inner filling). Repeat until all the mochi has been used up. If you use gloves, it'll make it a lot easier here!

Place the mochi ball in the middle of the flattened cookie. Pinch the sides of the cookie dough together and roll into a smooth ball
Gently flatten the mochi cookie dough using your palm once on the baking tray
