Preparation Steps

• Preheat oven to 350°F (175°C). Grease and flour a 9-inch round cake pan.
• In a large bowl, whisk together flour, granulated sugar, brown sugar, pumpkin pie spice, baking soda, and salt for the cake.
• Add the softened butter and mix until the mixture resembles coarse crumbs.
• In a separate small bowl, whisk together the egg, pumpkin puree, and milk.
• Add the wet ingredients to the dry ingredients and mix until just combined. Do not overmix.
• Pour half of the batter into the prepared cake pan and spread evenly.
• In a small bowl, combine the flour, brown sugar, and pumpkin pie spice for the streusel topping. Cut in the cold butter with a pastry blender or your fingers until the mixture is crumbly.
• Sprinkle half of the streusel topping evenly over the batter in the pan.
• Pour the remaining cake batter over the streusel and spread evenly.
• Sprinkle the remaining streusel topping over the second layer of batter.
• Bake for 30-35 minutes, or until a wooden skewer inserted into the center comes out clean.
• Let the cake cool in the pan for 10 minutes before inverting it onto a wire rack to cool completely.
