This is my favorite treat that my husband makes for me all the time (because he's wonderful like that). If you're a peanut butter fan, you'll love this. If you don't like peanut butter, you'll probably still love this. It's quick and easy.
8 cups popcorn
1/2 cup sugar
1/2 cup Karo syrup
1/2 cup smooth peanut butter
Melt together the sugar, Karo syrup, and peanut butter in a sauce pan on low heat. For the smoothest sauce, combine the sugar and Karo syrup first until it's not gritty, then add the peanut better until it's mixed in, but not cooked. Remove the unpopped kernels from the popcorn, pour the sauce all over the popcorn, and stir it until it's well-covered.
My favorite addition to this recipe is to sprinkle in milk chocolate chips while I'm coating the popcorn with the sauce. Mmm! It's so good!
