Preheat the oven to 350 degrees Fahrenheit (175 degrees Celsius)
Place 7 stroopwafels on a parchment lined baking sheet.
Top each stroopwafel on the baking sheet with a marshmallow and bake in the preheated oven to 5 minutes for the marshmallow to soften.
Remove from the oven and top each marshmallow stroopwafel with the remaining stroopwafel to make a sandwich. Set aside to cool.
Toast the chopped pecans in a dry skillet over medium/low heat, stirring frequently, until you can smell the nuts. Remove from the heat and set aside to cool.
Add the chocolate chips and the shortening to a microwave-safe bowl and microwave on medium power for 1-minute intervals, stirring between each interval, until the chocolate is melted and smooth.
Add a wire rack inside the baking sheet and return the stroopwafel sandwiches to the baking sheet on top of the rack.
Top each stroopwafel sandwich with melted chocolate and use a knife or offset spatula to evenly spread the chocolate over the sandwich.
Sprinkle each s'mores stroopwafel sandwich evenly with the toasted pecans and a pinch of finishing salt. Allow the chocolate to set and serve as desired.
