Preheat your oven to 350°F (175°C) and prepare a 9x5 inch loaf pan by greasing and flouring it. In a medium bowl, whisk together the flour, baking powder, and salt, then cream the softened butter and granulated sugar until light and fluffy in a separate large bowl.

Beat in the eggs one at a time into the creamed mixture, then stir in the vanilla extract. Gradually add the dry ingredients to the wet ingredients, alternating with the milk, mixing until just combined and then folding in the chopped fresh peaches.

Pour the batter into the prepared loaf pan and bake for 50-60 minutes, or until a wooden skewer inserted into the center comes out clean. Let the cake cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.
