Method
Prepare the Pan and Streusel
- Preheat the oven to 350°F (175°C). Grease and line a 9×5-inch loaf pan with parchment paper.
- In a medium bowl, combine the flour, brown sugar, cinnamon, and pumpkin pie spice. Cut in the cold butter using a pastry cutter or fork until coarse crumbs form; stir in the pecans if using, then refrigerate.
Mix the Batter
- In a large bowl, whisk together the flour, baking soda, baking powder, pumpkin pie spice, cinnamon, and salt.
- In another bowl, whisk together the pumpkin purée, eggs, granulated sugar, brown sugar, vegetable oil, sour cream, and vanilla until smooth.
- Fold the wet ingredients into the dry ingredients until just combined, then pour the batter into the prepared loaf pan and smooth the top.
- Evenly sprinkle the chilled streusel mixture over the batter, covering the entire surface.
Bake and Finish
- Bake at 350°F (175°C) for 60–70 minutes, until a toothpick inserted into the center comes out clean or with a few moist crumbs attached.
- If needed, loosely cover with foil during the final 15 minutes to prevent over-browning.
- Cool in the pan for 15 minutes before transferring to a wire rack.
- Whisk together the glaze ingredients and drizzle over the cooled loaf before slicing, if using.
Notes
For a tighter crumb, fold the wet into the dry until no dry streaks remain—overmixing can make the loaf tougher. Store the cooled loaf in an airtight container at room temperature for up to 3 days or in the refrigerator for up to 5 days; freeze slices for up to 2 months. For a dairy-free option, replace sour cream with plain unsweetened non-dairy yogurt and use non-dairy milk in the optional glaze if desired.
