Fill ice cream cones with chocolate chips, caramel candies, and pecans as desired. Set aside.
In a large bowl, combine popcorn and chopped pecans. Set aside.
In a sauce pot, melt butter. Add marshmallows. Stir to combine with butter. Cook over medium heat until marshmallows are melted. Remove from heat and add optional maple extract. Stir to combine.
