Method
Prep
- Preheat the oven to 350F and grease a 9x5 loaf pan.
- Make streusel by cutting cold butter into flour, brown sugar, and cinnamon until crumbly, then refrigerate.
Make the batter
- Whisk all-purpose flour, baking soda, pumpkin pie spice, cinnamon, and salt until evenly combined.
- Whisk pumpkin puree, granulated sugar, brown sugar, vegetable oil, eggs, vanilla extract, and sour cream until smooth.
- Fold the dry ingredients into the wet ingredients until just combined, then fold in 1 cup chocolate chips.
Bake
- Pour the batter into the loaf pan and scatter the remaining chocolate chips over the top.
- Generously cover the batter with the refrigerated streusel topping.
- Bake for 60-65 minutes at 350F until a toothpick comes out clean.
- If the top is browning too fast, tent loosely with foil after 35 minutes of baking.
Notes
Pro tip: Refrigerating the streusel helps it stay crumbly so it bakes into a crisp, caramelized top. Store in an airtight container at room temperature up to 3 days, or refrigerate up to 5 days. Freeze slices wrapped tightly for up to 2 months. For a dairy-light option, use lactose-free sour cream and swap the butter in the streusel for a plant-based butter substitute.
