Equipment
Method
Preheat and prep
- Preheat oven to 350F, then grease a 9x13 pan for easy release after baking.
- Set the pan aside while you make the streusel and batter so the topping stays thick and crumbly.
Make pecan streusel
- Cut cold butter into the flour, brown sugar, and cinnamon until crumbly, using a gentle rubbing motion for pea-size bits (about 2-3 minutes).
- Stir in the chopped pecans until evenly distributed, and keep the mixture cool so it bakes into a crunchy top.
Mix pumpkin cake batter
- Beat butter and brown sugar until smooth and lighter in color, then add eggs one at a time and mix until incorporated.
- Add pumpkin puree, sour cream, and vanilla, and mix just until the batter looks cohesive and thick.
Combine and bake
- Fold in the dry ingredients until no dry streaks remain, then spread the batter evenly in the greased pan.
- Scatter pecan streusel generously over the top as a thick, even layer, with visible crumble peaks.
- Bake at 350F for 45-50 minutes, until a toothpick in the center comes out clean and the crumble is golden brown.
Notes
For clean slices, cool the cake 15-20 minutes after baking so the pumpkin crumb firms up under the pecan streusel. Store covered in the refrigerator up to 4 days; rewarm individual portions in the microwave for 10-15 seconds. Freezing is yes—wrap tightly and freeze up to 2 months. For a lighter option, use low-fat sour cream (texture remains tender though slightly less rich).
