Cinnamon Sugar Caramel Corn

1 stick butter
1/4 cup corn syrup
Air popped popcorn-I used 1/4 cup kernels
1 cup brown sugar
1 /2 teaspoon salt
1 teaspoon vanilla

Cinnamon and Sugar mix and white chocolate if you want it

Preheat oven to 250F.

Pop popcorn using your air popper! Spread popcorn out onto two large baking sheets. Make sure it is evenly spread between the two pans.

Melt butter in a saucepan over medium heat. Add in sugar, corn syrup and salt; stir until well combined. Bring to a boil, stirring constantly with a wooden spoon. Once the mixture comes to a rapid boil, let it boil for 5 minutes without stirring. Stir in the vanilla.

Gradually pour the caramel mixture over the popped corn, mixing well on the pans. You can do this in a bowl but why dirty more dishes? I do it right on the pans. 
Sprinkle popcorn with the cinnamon and sugar mixture.

Bake in preheated oven for about 30 minutes, make sure you stir it often. Maybe every ten minutes or so. 
Remove from pan and sprinkle with a little more cinnamon and sugar. You can drizzle white chocolate over the popcorn if you wish!
