Sarah's Caramel Popcorn/Puffs

1 lg bag corn puffs (walmart or winco have them)
1 cup margarine
1/2 cup light karo syrup
2 cups brown sugar
1-2 tsp vanilla (Sarah only uses one but I always double the vanilla in any recipe cause I love it!)
1/2 tsp baking soada

Bring margarine, karo syrup and brown sugar to a boil, turn down to low and cook for 5 minutes continuously stirring. Add vanilla and baking soda.

In a clean grocery bag, pour over corn puffs or freshly popped popcorn and shake up to distribute syrup mixture evenly. Serve and enjoy!!
