Prepare and mix
- Preheat the oven to 350°F (175°C). Grease a 9×5-inch loaf pan and line it with parchment paper.
- In a large bowl, whisk together all-purpose flour, baking soda, baking powder, pumpkin pie spice, ground cinnamon, ground nutmeg, and kosher salt until evenly combined.
- In another large bowl, whisk pumpkin purée, eggs, granulated sugar, light brown sugar, pure maple syrup, vegetable oil, sour cream, and pure vanilla extract until smooth.
- Fold the wet ingredients into the dry ingredients until just combined, then gently fold in toasted walnuts; do not overmix.
Bake and finish
- Transfer the batter to the prepared loaf pan and smooth the top, then sprinkle with toasted walnut halves and coarse sanding sugar.
- Bake for 55–65 minutes, or until a toothpick inserted into the center comes out clean or with only a few moist crumbs attached; if the top browns too quickly, loosely cover with foil during the final 15 minutes.
- Cool the bread in the pan for 15 minutes, then transfer it to a wire rack; if desired, whisk together the maple glaze ingredients and drizzle over the cooled loaf before slicing.
Notes
For best texture, fold the batter only until the dry flour disappears—overmixing can make the crumb tough. Store tightly wrapped at room temperature for up to 3 days or refrigerate up to 5 days; freeze baked slices up to 2 months. Dietary swap: for a gluten-free version, use a 1:1 gluten-free all-purpose flour blend with a similar bake-time expectation.
