KBB#8: Bitter Chocolate Peppermint Biscuits

KBB (Indonesian Baking Club) challenge this time: Bitter Chocolate Peppermint biscuits, hosted by Ellen and Arfi .
The thickness of biscuits should be 2 mm, I made 5 mm ! Then, sandwich three biscuits with peppermint icing. Huaaaa...to eat those biscuits, I´ve to open my mouth widely. I think, two layers enough!
