Cinnamon Caramel Corn with White Chocolate

I changed up the recipe, a little for what I had, but the original is here at http://www.ourbestbites.com/2009/09/cinnamon-caramel-corn-with-pecans-white.html

8 C popped popcorn (one bag popped, could use more it was really too sugary, and I only had butter flavor, I think it would be better with a lighter popcorn)
1/2 C peanuts
1 C brown sugar
3/4 t cinnamon
1/4 C Light Karo syrup (or honey-didn't try that)
1 stick real unsalted butter (1/2 C)
1/2 tsp. baking soda
1 tsp. vanilla
White chocolate chips melted

Preheat oven to 250 degrees

Place popcorn and chopped peanuts in a large bowl and set aside. And by large bowl, I mean like, twice as big as you think you really need.
Combine brown sugar and cinnamon in a big, microwave-safe bowl. Like a 2-quart bowl or Pyrex measuring bowl. Again, use a bowl larger than you think. It's really important to incorporate the cinnamon into the brown sugar at this point.
Chop butter into chunks and place on top of sugar mixture. Pour corn syrup (or honey) over the top of everything.
Microwave on high for 30 seconds (just to soften the butter a bit) and then stir to combine.
Return to microwave and heat for 2 minutes. (Longer if needed)
By this point it should be nice and bubbly.beware that if you over cook it, it will reach the hard candy stage and you'll end up with a giant clump of tasty concrete-like substance with little popcorn pieces stuck to it. Remove from the microwave and add in vanilla and baking soda. Spread over popcorn, stir. Place in pan, place in oven and bake for 30 minutes, stirring every 10 minutes. Take out drizzle chocolate over and yummyness.
