Preheat Oven & Prep Pan: Preheat your oven to 356ºF (180ºC) fan-forced. Grease a 9-inch x 5-inch (25cm x 15cm) loaf tin with butter and line with parchment paper. Note: For non-stick tins, line the base with parchment and lightly grease and flour the sides for smooth cake release. Set aside.
Mix Dry Ingredients: In a large mixing bowl, add flour, baking powder, baking soda, pumpkin pie spice, and salt. Whisk together until well combined. Set aside.
Combine Wet Ingredients: In a medium-size mixing bowl, add the oil, eggs, yogurt and both sugars. Whisk until well combined.
Combine: Add the wet ingredients to the dry ingredients and whisk until incorporated and no flour is visible, being careful not to overmix.
Transfer Batter: Pour the batter into the prepared loaf pan.
Bake: Bake for 45-50 minutes, mine took 50 minutes, or until a toothpick inserted into the middle comes out clean or with a few moist crumbs.
Cool: Remove from the oven and allow the bread to cool in the pan for 15 minutes, then transfer to a wire rack to cool completely. Enjoy!
