Caramel Popcorn Cookies

Preheat oven to 350°. Combine granulated sugar, brown sugar, butter, and vanilla in a large bowl; beat with a mixer at medium speed until fluffy. Add egg; beat just until blended. Beat in flour, baking soda, and 1/4 teaspoon salt.

Stir crushed hard caramel candies and 1/8 teaspoon salt into cookie dough. Prepare microwave popcorn according to package directions. Stir 3 cups prepared popcorn into cookie dough with a rubber spatula. Drop dough by tablespoonfuls 2 inches apart on parchment paper-lined baking sheets. Bake 10 to 12 minutes or until lightly browned.
