In medium bowl, stir together flour, baking powder, baking soda, cinnamon and salt. Set aside. In large mixer bowl, beat the 1 ½ cups sugar and butter at medium speed until light and fluffy. Add eggs, peach mixture and vanilla. Beat at low speed until well combined. Add flour mixture; beat at low speed just until combined. Stir in nuts.
