Spray a 9" x 13" baking dish with non-stick spray. Set aside.

In a large saucepan, combine the butter, molasses, cinnamon, and ginger and allow to melt while stirring. Add the marshmallows and stir until completely melted. Remove from heat. Add Rice Krispies cereal and stir until well-coated.

Using a spatula sprayed with non-stick spray, gently press mixture into baking pan. Allow to cool completely before cutting into squares or into desired shapes with a cookie cutter.

You can drizzle them with spiced white chocolate before or after cutting. You can also omit the drizzle and leave them as is!

In a microwave safe bowl, melt the white chocolate in the microwave in 15 second increments on HIGH, stirring after each session until completely smooth.

Stir in cinnamon and ginger.

Pour melted chocolate into a large plastic bag with the corner snipped off, a decorating bottle, or a piping bag fitted with a small decorating tip. Drizzle the white chocolate onto the cut treats.

Allow chocolate to set before serving or storing. Store treats in an airtight container up to one week.
