8 cups popped popcorn
½ cup unsalted butter
1 cup brown sugar
¼ cup light corn syrup
½ tsp baking soda
1 tsp vanilla extract
¾ cup chocolate chips
Heat a saucepan and melt butter. Add brown sugar and corn syrup and stir until sugar melts. Bring to a boil and cook for 3-4 minutes.
Remove caramel from heat and stir in baking soda and vanilla. The mixture will bubble up.
Spread out popcorn on a lined baking sheet and pour caramel sauce over it. Coat evenly.
Sprinkle chocolate chips while caramel is still warm and runny so they can stick. Set in the fridge and break into clusters to serve.
