Why have just one cookie when you can make a sandwich?
Why This Recipe Works
It was best to underbake our Chocolate-Peppermint Sandwiches rather than risk overbaking, as they were best when moist and chewy. Using only a small amount of peppermint extract ensured that it didn’t overwhelm the chocolate flavor. To give the Chocolate-Peppermint Sandwiches a more festive feel, we dyed the filling either green or red.
