Add parchment paper to an 8 x 8 square pan (leave an overhang). Set aside.

Add butter into a large pot over medium heat. Allow to melt.

Once melted, add miniature marshmallows and mix constantly until thoroughly melted.

Once marshmallows are completely melted, add molasses, ground ginger and ground cinnamon. Fold and mix thoroughly.

Remove gingerbread marshmallow mixture from the heat and add cereal. Mix until cereal is well-coated with the marshmallow mixture.

Gently pat the rice cereal treats into the lined pan and smooth out evenly. Let rest for about one hour. Cut into 9 squares and serve.
