Ingredients
Scale
- 2 cups all-purpose flour
- 1 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1/2 teaspoon salt
- 1 tablespoon pumpkin pie spice
- 1 cup canned pumpkin puree (not pie filling)
- 1/2 cup vegetable oil
- 2 large eggs
- 1 cup granulated sugar
- 1 teaspoon vanilla extract
- 1/2 cup all-purpose flour (for streusel)
- 1/2 cup packed light brown sugar (for streusel)
- 1/4 cup cold unsalted butter, cubed (for streusel)
- 1 teaspoon ground cinnamon (for streusel)
Instructions
- Preheat your oven to 350°F (175°C). Grease and flour a 9-inch square baking pan or line it with parchment paper for easy removal. Set the pan aside while you prepare the mixtures.
- In a small bowl, combine the 1/2 cup flour, brown sugar, and cinnamon for the streusel. Use a pastry cutter or your fingers to work the cold, cubed butter into the mixture until it resembles coarse crumbs. Place the bowl in the refrigerator to keep the butter cold while you mix the cake batter.
- In a medium-sized mixing bowl, whisk together the 2 cups of all-purpose flour, baking soda, baking powder, salt, and pumpkin pie spice. Ensure there are no large clumps of spice so the flavor is evenly distributed.
- In a separate large bowl, whisk together the pumpkin puree, vegetable oil, eggs, granulated sugar, and vanilla extract until the mixture is smooth and well combined.
- Gradually add the dry ingredients to the wet ingredients. Use a spatula to fold the mixture together gently until just combined. Be careful not to overmix, as this can make the coffee cake tough.
- Spread half of the pumpkin batter into the prepared baking pan. Sprinkle half of the chilled streusel mixture evenly over the batter. Carefully spread the remaining batter over the streusel layer, then finish by topping the cake with the rest of the streusel.
- Place the pan in the center of the oven and bake for 40 to 45 minutes. To check if it is done, insert a toothpick into the center; it should come out clean or with just a few moist crumbs. Allow the cake to cool in the pan for at least 15 minutes before slicing.
