Step 1: Get Your Oven Ready & Prep Your Pans: Preheat your oven to 350 degrees F (175 degrees C). Grease and flour three mini loaf pans or one standard large loaf pan with non-stick cooking spray or grease and flour.
Step 2: Wet Ingredients Party: In a medium-sized bowl, combine diced peaches, vegetable oil, sugar, eggs, sour cream, and vanilla extract. Stir until well combined. A few lumps from peaches are okay.
Step 3: Add the Dry Goodies: Measure out flour, baking soda, and salt. Add these dry ingredients to the bowl with the wet mixture.
Step 4: Mix Just Enough: Gently stir the ingredients together until just combined. Do not overmix; a few streaks of flour are acceptable. Overmixing can result in tough bread.
Step 5: Into the Pans: Pour the batter evenly into the prepared loaf pans. Divide among three mini pans or pour all into one large pan. Smooth the top if needed.
Step 6: Time to Bake!: Place the pans into your preheated oven.
Step 7: Bake Until Golden: Bake mini loaves for about 25-30 minutes, or a standard large loaf for about 50-55 minutes. The bread is done when the top is golden brown and a wooden skewer or toothpick inserted into the center comes out clean (maybe with a few moist crumbs).
Step 8: Cool Down: Carefully remove pans from the oven. Let cool in the pans for about 10-15 minutes before turning out onto a wire rack to cool completely. Cooling allows the bread to set up for cleaner slices.
