Ingredients Method

Ingredients
  

  • 2 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1 teaspoon baking powder
  • 1 teaspoon salt
  • 2 teaspoons pumpkin spice blend
  • 1 cup granulated sugar
  • 1/2 cup brown sugar
  • 3/4 cup vegetable oil
  • 4 large eggs
  • 1 cup pumpkin puree
  • 1 teaspoon vanilla extract
  • 1 cup rolled oats
  • 1/2 cup chopped pecans or walnuts
  • 1/4 cup melted butter

Method
 

  1. Preheat the oven to 350°F (175°C). Grease and flour a 9x13 inch baking pan.
  2. In a large bowl, whisk together the flour, baking soda, baking powder, salt, and pumpkin spice blend.
  3. In another bowl, mix the granulated sugar, brown sugar, oil, and eggs until well combined. Stir in the pumpkin puree and vanilla extract.
  4. Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
  5. Pour the batter into the prepared pan, spreading it evenly.
  6. In a separate bowl, mix the oats, nuts, melted butter, and a tablespoon of flour to prepare the crumble topping.
  7. Sprinkle the crumble mixture evenly over the top of the cake batter.
  8. Bake for 35-40 minutes, or until a toothpick inserted into the center comes out clean.
  9. Remove from the oven and allow to cool in the pan for about 15 minutes before transferring to a wire rack.
  10. Serve warm or at room temperature, optionally dusted with powdered sugar or accompanied by whipped cream.
