1½cups(337g)pumpkin pureeslightly less than a 15oz can
Instructions
Preheat oven to 350°F. Spray a 9 inch round pan with baking oil containing flour and place a 9 inch parchment round on the bottom.
Cinnamon Streusel Topping
Melt the butter in a microwave safe bowl. Whisk together the flour, light brown sugar and cinnamon. Stir in the melted butter until everything is combined well.Set aside while making the batter.
Pumpkin Spice Cake
In a medium bowl, whisk together the flour, baking soda, baking powder, salt, cinnamon and pumpkin pie spice.
In a large bowl, whisk together the oil and sugars really well (about 1 minute). Stir in the eggs one at a time, followed by the vanilla extract and pumpkin puree, mixing well after each addition.Scrape the sides of the bowl as needed to incorporate all ingredients.
Gently stir the dry ingredients into the wet ingredients until no visible flour streaks remain.
Pour the batter into the prepared cake pan and then evenly sprinkle streusel topping over it.
Bake at 350°F until the top feels firm and a toothpick comes out of the center clean (about 42-48 minutes). Let the cake cool in the pan for 15-20 minutes.
Once the pan is cool enough to touch, place a plate on top and carefully flip it over so that the cake lands upside-down on the plate. Then, place a wire rack or another plate over the cake and flip it again so that the cake is right-side-up.
Let the cake finish cooling and then slice it into equal triangles and enjoy!
