In a bowl, combine half a cup of pumpkin with two cups of thick Greek yogurt, two tablespoons of maple syrup, and a teaspoon of pumpkin spice.
Spread the mixture evenly on a lined tray to create a thin layer.
Top the mixture with chopped pecans.
Drizzle melted dark chocolate over the top.
Place the tray in the freezer for 3 hours or until the bark is firm.
Once frozen, break the bark into pieces.
