Line a 9×5 loaf pan with parchment paper. Combine almond butter, pumpkin purée, maple syrup, melted and cooled coconut oil, vanilla, and pumpkin pie spice in a medium bowl.
Mix to combine thoroughly.
Transfer to the lined pan, smooth with the back of a spoon or spatula until evenly distributed, and top with chocolate chips, crushed pecans, and flaky salt.
Freeze for 2 hours until fudge is firm.
Slice into squares, and enjoy! Store in freezer for 2 weeks.
