Preheat oven to 350 degrees. Grease a 9"x13" pan, set aside.
Place butter and both sugars in mixing bowl of stand mixer and with the paddle attachment beat until sugars are incorporated into butter. Add in eggs and vanilla and beat until light and fluffy (about 1-2 mins). Add in cinnamon, baking soda and 1 cup of baking mix and mix until incorporated, add additional baking mix one cup at a time until mixed well. Add in cinnamon chips and walnuts mix until evenly distributed into the batter. The batter will be thick.
Place batter into prepared 9"x13" pan. Use back of a spatula or your hands to press dough evenly into pan.
Bake for 25 mins in preheated oven. Do not over bake. When done allow to cool completely before glazing bars.
Place powdered sugar in small mixing bowl and add in soft butter. Using the back of a spoon work the butter into the powdered sugar as much as you can. Adding milk one teaspoon at a time into powdered sugar butter mixture, mix thoroughly with a spoon until desired consistency is reached. You want the glaze to be thin enough to drizzle over top of bars but not watery. If the glaze is too thin add more powdered sugar. Drizzle over completely cooled bars. Allow the glaze to set up for about an hour. Cut into squares and enjoy.
