Method
Prepare the pan
- Heat the oven to 350°F.
- Coat a 9x13-inch baking dish with nonstick cooking spray.
Make the streusel
- Stir together the flour, brown sugar, and cinnamon.
- Work in the cold butter with your fingertips until the mixture forms coarse crumbs.
- Refrigerate the streusel while you make the cake.
Make the cake
- In a large bowl, whisk together the flour, granulated sugar, baking powder, baking soda, salt, and pumpkin pie spice.
Whisk the wet ingredients
- In a medium bowl, whisk together the pumpkin puree, oil, eggs, sour cream, and vanilla until smooth.
- Fold the wet ingredients into the dry ingredients just until no dry streaks remain.
Assemble and bake
- Spread the batter evenly in the prepared dish.
- Sprinkle the streusel over the top.
- Bake for 35 to 40 minutes, until a toothpick inserted in the center comes out with a few moist crumbs.
Cool the cake
- Let the cake rest in the dish for at least 20 minutes before slicing.
Notes
For tender cake, fold the wet ingredients into the dry just until no dry streaks remain. Store covered in the refrigerator for up to 4 days; freezer: yes, freeze slices for up to 2 months. For a dairy-free variation, use dairy-free butter and sour cream.
