Grease a glass loaf pan with cooking spray

In a large saucepan, melt coconut oil over medium heat. Stir in pecan butter and mix until well combined.

Add the mini marshmallows and stir until melted and smooth. Remove from heat.

Add the rice cereal and chopped pecans to the marshmallow mixture until they are well coated.

Pour the mixture into a greased (cooking spray works fine) pan and press down lightly so that the tops are smooth.

Let it cool for about an hour. Cut into squares, and drizzle with molasses if desired.
