Root Beer Float Sandwich Cookies

I always got root beer candies in my stocking. The crunch of the sugar on these cookies reminds me of those candies, while the insides are chewy and soft.—Michelle Sion, Darien Center, New York

    These cookies are amazing! I saw the recipe and bought the root beer concentrate. On yet another cold, snowy day my daughter and grandson came over and we decided to make something ‘summery’ to enjoy. WOW! They made the house smell wonderful and they do taste exactly like a root beer float. These take some time to make but they are certainly worth it. Thank you for sharing this recipe.
