Preheat oven to 250 degrees. Line a large baking sheet with Parchment paper. Prepare the popcorn according to the directions, and empty it into a large bowl, and set aside. In a sauce pan, on medium heat, melt the butter. Add the corn syrup, brown sugar and salt. Stir to combine and until the sugar is dissolved. Turn up the heat to high, and let the mixture come to a boil. Boil for 2-4 minutes, until the caramel turns dark. Take it off the heat and stir in the baking soda. Pour the caramel onto the popcorn and fold in until the popcorn is covered with the sauce evenly. Empty the popcorn onto the baking sheet, spread out to a single layer. Bake for 30 minutes, take out and sprinkle 1 Tbsp. cappuccino onto the popcorn. Turn over with spoon, bake 10 minutes, and add another Tbsp. of cappuccino, turn over again. Bake another 10 minutes. Take out and cool, serve immediately! This treat gets better as it sits! It is also a great party favor to give your guests in a small bag.
