Here is all you need for this Caramel Popcorn recipe:-Already popped popcorn-Corn syrup-Dark brown sugar-Vanilla extract-Butter-Baking soda-Kosher salt
Start by lining two baking sheets with parchment paper and preheating the oven to 250 degrees F. Add the popcorn to a very large bowl and then melt butter in a medium saucepan.
After the butter melts, stir in the kosher salt, corn syrup, and dark brown sugar. Bring it to a boil over medium heat, stirring constantly. Boil the mixture for four minutes without stirring. Then, remove it from the heat and add the vanilla extract and baking soda.
Now, pour this mixture over the popcorn and stir it around with a wooden spoon or spatula until it is all coated. Pour popcorn onto the two prepared baking sheets and bake for one hour, stirring every 15 minutes. Let it cool before breaking it up into small pieces, if necessary.
