Line a loaf pan with parchment paper and set it aside.
Then, add the cashew butter, pumpkin puree, maple syrup, melted coconut oil, vanilla, pumpkin spice, and salt to a large mixing bowl. Mix until a thick and smooth batter forms.
Pour the fudge batter into the lined loaf pan and use a spatula to spread the fudge evenly in the pan. Then, sprinkle the chocolate chips on top.
Add the pan to the freezer for at least 2-3 hours to set, but ideally let it set overnight.
Once the fudge has frozen through, remove it from the freezer and cut it into 8 evenly sized squares.
Enjoy immediately and store any remaining fudge slices in a freezer-safe container or bag so they do not melt.
