Cream together butter and sugar. Add eggs and beat well. Beat in extracts.
In a separate bowl combine flour and salt. Add to the creamed mixture. Mix until combined.
In a seperate bowl, combine peach pie filling, brown sugar and cinnamon.
Grease a 15x10x1 pan or 9×13, whichever one you decide to use. (I used a 15x10 pan). Spread 3 cups batter in a 15x10x1 (Also works with 9×13- baking time will at least be 35 minutes) Spread with pie filling. Drop remaining batter on top of pie filling.
Bake at 350 for 25-30 minutes or until toothpick comes clean. Cool on wire rack. Combine powdered sugar and milk for the glaze and drizzle over the bars.
