Update: I made these this weekend, and they were a hit with my book club and at mom and dad's house. I'm hanging on to this one! Ingredients (Cookies) •1 c. butter •2 c. brown sugar •2 eggs •1 c. buttermilk •3/4 tsp rootbeer concentrate (Make sure if you're using a bottle of concentrate that has already been in your cupboard for awhile that it isn't old. I've known people who have used old concentrate and they end up pouring almost the entire bottle in before they get even a hint of rootbeer flavor. That and the color doesn't turn out nearly right.) •4 c. flour •1 tsp baking soda •1 tsp salt Ingredients (Frosting) •3 1/2 c. powdered sugar •3/4 c. butter •3 Tbsp water •1 1/4 tsp rootbeer concentrate Directions 1.Combine all ingredients for the cookies in a large bowl or in a KitchenAid. 2.Drop the dough onto a greased cookie sheet (about a tablespoon size of dough balls) and bake for 10-12 minutes at 375 degrees. 3.While the cookies are baking, place the dough in the refrigerator. (It is good to keep your cookie dough in the refrigerator between batches to keep the dough firm.) Combine all the ingredeints for the frosting in a medium bowl and mix together well, whether it be with your KitchenAid or an electric hand mixer. 4.Frost the cookies after they have been given time to cool. Enjoy!
