Caramel Puff Corn

I love to make this when people come over. They go crazy over it! Yum!!

1 c. brown sugar
1/2 c. butter
1/4 c. light corn syrup
1/4 tsp. baking soda
1 tsp. vanilla
1 bag hull-less popcorn, popped (by the potato chips in the grocery store)

Combine brown sugar, butter and corn syrup; boil for 2 minutes, stirring constantly. Remove from heat. Stir in baking soda and vanilla; mix thoroughly. Pour over popped corn.

Bake in large cookie sheet at 250 degrees F for 30-45 minutes. Cool slightly, break apart, and store in plastic bags.
