Instructions
Cake:
Preheat oven to 350°. Spray a 9x13-inch baking dish with baking spray.
In a large bowl, whisk together 2 cups all-purpose flour, 1 teaspoon ground cinnamon, 1 teaspoon freshly grated nutmeg, 1/4 teaspoon ground cloves, 1/4 teaspoon ground allspice, 1/2 teaspoon ground ginger, 1 teaspoon kosher salt, 1/2 teaspoon baking soda, and 1 teaspoon baking powder. Set aside.
In the bowl of a stand mixer fitted with the paddle attachment, cream ½ cup unsalted butter, softened and ¼ cup vegetable oil for 2 minutes, then add 1 cup firmly packed light brown sugar and 1 cup granulated sugar and beat at medium-high speed until creamy, 5-7 minutes, scraping sides as needed.
Reduce mixer to low and add 2 large eggs, room temperature, one at a time, beating until just blended after each addition. Add 1 15-ounce can pure pumpkin puree, beating just until blended. Add 1/2 cup sour cream and blend.
Gradually add flour mixture to butter and mix on low until flour is incorporated into the batter. Don’t overmix. Stir in 1 teaspoon vanilla.
Pour into prepared dish, smoothing top with offset spatula. Sprinkle with streusel. Bake until tester comes out clean, about one hour. Start checking around 50 minutes. Allow cake to cool before serving.
Streusel:
Stir together 1 cup brown sugar, 1/4 cup granulated sugar, 1 1/2 cups all-purpose flour, and 1 tablespoon cinnamon. Stir in 7 tablespoons melted butter just until the mixture is moistened and no flour is visible or sandy.
