Line a baking sheet with foil and coat with cooking spray or butter.
In a 12 inch non-stick skillet, combine sugar, nuts, Karo syrup and pumpkin pie spice. Cook over medium heat, stirring constantly with a wooden spoon, for about 20 minutes or until it becomes caramel color.
Remove from heat and add butter and baking soda, stirring until just combined.
Pour onto prepared baking sheet and let cool completely.
Break into pieces and store in an airtight container.
Former restaurant manager (and waitress, bartender, etc). I love food: eating, trying new recipes, shopping for it, talking/emailing about it, etc. My foodie friend and pen pal got me interested in recipe contests and also turned me on to food52 and now I'm obsessed!
