Carefully break graham cracker sheets into squares and lay them out on a sheet of waxed paper.

In a medium microwave-safe bowl with high sides, melt the white almond bark on high power for 1 minute. Stir well. Continue microwaving in 30-second intervals, stirring often, until almond bark is fully melted and smooth.

Dip the ends of three marshmallows into the almond bark and press them on the back of a single graham cracker. Complete this step for the remaining marshmallows then cool them completely.

Once cooled, pick up each graham cracker with the marshmallows attached and dip the bare ends of the marshmallows into the melted almond bark. (You may need to microwave the almond bark for an additional 30 seconds to remelt it.) Place another graham cracker square on the top. Allow them to cool completely.

One at a time, dip each s'more fully into the melted white almond bark, making sure that they are completely covered. Use two forks to remove the s'mores, tap off the excess almond bark, and place them on a clean sheet of waxed paper to cool.

When the white dipped s'mores are cooled, melt the milk chocolate candy melts in a microwave-safe bowl on HIGH for 1 minute. Stir well. Continue heating in 30-second increments until the chocolate is melted and smooth. Dip each dipped s'more into the melted milk chocolate on the diagonal so that one half is white and the other half is chocolate brown, Tap off the excess and place the s'mores onto waxed paper to cool completely.

If desired, use a small paring knife or a vegetable peeler on the cooled s'mores to remove any excess chocolate that has pooled at the bottom.
