Preheat the oven to 350°F (175°C) and grease a 9x5-inch loaf pan with butter, dusting with granulated sugar.

In a large bowl, combine flour, salt, baking powder, and light brown sugar. Add spices and whisk until combined.

In another bowl, whisk the eggs, then add vegetable oil and milk, mixing until smooth.

Pour the wet ingredients into the dry ingredients and stir gently until just combined; the batter should be slightly lumpy.

Fold in the peaches gently, then transfer the batter to the prepared loaf pan.

Bake in the preheated oven for 60-70 minutes until golden brown and a toothpick comes out clean.

Cool in the pan for 10 minutes before transferring to a wire rack to cool completely.
