You'll see in the photos that I only dipped half of the graham cracker in the melted chocolate. That's just personal preference, and you can absolutely fully dip the graham crackers in chocolate. Place the graham cracker in the chocolate and allow it to fully cover one side. Using the tines of a fork, carefully flip the graham cracker and allow the chocolate to fully cover the other side and the edges. Lift the graham cracker from the chocolate with a fork and then gently nudge it onto the parchment-lined baking sheet with another fork or a toothpick. Do not use your hands as fingerprints will show up in the finished product.
