Method
Prep
- Preheat the oven to 350F and grease a 9x5 loaf pan so the loaf releases cleanly after baking.
- To make the crumb topping, cut cold unsalted butter into the flour, brown sugar, cinnamon, and nutmeg until large crumbs form, then refrigerate.
Mix the batter
- Whisk the dry bread ingredients (flour, baking soda, pumpkin pie spice, cinnamon, and salt) until evenly combined.
- Whisk the wet ingredients (pumpkin, sugar, brown sugar, oil, eggs, vanilla, and sour cream) until smooth.
- Fold the wet mixture into the dry mixture until just combined, then pour the batter into the prepared loaf pan.
Bake
- Scatter the crumb topping very generously over the top, covering every inch for a thick streusel layer.
- Bake at 350F for 60-65 minutes until a toothpick comes out clean, and tent with foil after 35 minutes to protect the crumb.
Notes
For best texture, keep the crumb topping cold in the refrigerator until the moment it hits the batter—warm butter can melt into the surface. Store the loaf tightly wrapped in the fridge for up to 4 days; freeze slices in a sealed bag for up to 2 months. For a lighter option, swap the oil with melted coconut oil in the same amount for a similar moist crumb.
