In a large mixing bowl combine the flour, baking soda, baking powder, cinnamon, and salt. Mix until well combined.
In a separate bowl cream together the sugar, eggs, and vegetable oil.
Add the wet ingredients to the dry and mix well until batter forms. Fold in diced peaches.
Pour into a greased loaf pan and bake for 35 minutes or until a toothpick comes out clean.
Glaze
In a small bowl combine powdered sugar and milk until powdered sugar has dissolved.
Brush or pour over loaf.
Notes
**Notes: refrigerate leftovers. I left skin on the peach for easy preparation, can peel/ blanch if desired.If the top starts to brown too quickly cover with tin foil.
