For the Cake
  • 1 cup canned pumpkin puree
  • 1 cup granulated sugar
  • 1/2 cup vegetable oil
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1 1/2 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon ground nutmeg
  • 1/4 teaspoon ground ginger
For the Crumble Topping
  • 1/2 cup all-purpose flour
  • 1/2 cup brown sugar
  • 1/2 teaspoon cinnamon
  • 1/4 cup cold butter cubed
For the Sweet Topping
  • 1/2 cup powdered sugar
  • 2 tablespoons milk

Method
 

Preparation
  1. Preheat your oven to 350°F (175°C). Grease and flour a 9-inch round cake pan.
  2. In a large mixing bowl, whisk together the pumpkin puree, sugar, vegetable oil, eggs, and vanilla extract until smooth and creamy.
  3. In another bowl, sift together the flour, baking soda, baking powder, salt, cinnamon, nutmeg, and ginger. Slowly add the dry ingredients to the wet mixture, stirring until just combined.
  4. In a small bowl, mix together the crumble topping ingredients: flour, brown sugar, and cinnamon. Cut in the cold butter until the mixture resembles coarse crumbs.
Baking
  1. Pour the cake batter into the prepared pan and sprinkle the crumble topping evenly on top.
  2. Bake for 30-35 minutes or until a toothpick inserted into the center comes out clean.
  3. While the cake cools, whisk together the sweet topping ingredients: powdered sugar, milk, and vanilla extract until smooth.
Serving
  1. Once the cake has cooled, drizzle the sweet topping over the crumble. Slice up the cake and enjoy!

Notes

Feel free to add chocolate chips or chopped nuts for an extra crunch. Store leftovers in an airtight container at room temperature for 2-3 days, or refrigerate for up to a week.
