Twix Caramel Popcorn

A friend made this the other day and it was DELICIOUS!!  The recipe comes from Six Sisters Stuff cookbook.  It is pretty rich...so a little bit is enough for me!

Ingredients:
5 quarts plain air popped popcorn (equals about 1 cup popcorn kernels)
1 cup butter
2 cups light brown sugar
1/2 cup light corn syrup
1 teaspoon salt
1/2 teaspoon baking soda
1 teaspoon vanilla extract
24 “fun size” Twix candy bars, chopped into bite-size pieces
2 cups milk chocolate chips, melted

Directions:
Preheat oven to 250 degrees and place the popped corn in a bowl. Set bowl aside.
In a saucepan melt butter over medium heat. Stir in the brown sugar, corn syrup, and salt. Bring to a boil, stirring constantly. Let mixture oil for about 4 minutes (without stirring it). Remove saucepan from heat and mix in baking soda and vanilla extract. Pour caramel over popcorn in the bowl and gently stir until all of the popcorn is covered.
Spread popcorn on two large cookie sheets and bake in preheated oven, stirring every 15 minutes, for about an hour. Remove popcorn from oven and let cool completely.
Break popcorn into pieces and mix in chopped Twix candy bars. Drizzle melted chocolate chips all over the popcorn. Let the popcorn cool until the chocolate hardens (which takes about 30 minutes- if you can wait that long!). Store at room temperature in an airtight container.

Makes about 15 servings.
