Ingredients:

  • 1 1/2 cups all-purpose flour
  • 1 tsp baking soda
  • 1/2 tsp salt
  • 1 tbsp pumpkin pie spice
  • 1/2 cup vegetable oil
  • 1 cup granulated sugar
  • 2 large eggs
  • 1 cup pumpkin purée
  • 1 tsp vanilla extract
  • 1/2 cup all-purpose flour
  • 1/2 cup brown sugar
  • 1 tsp ground cinnamon
  • 4 tbsp cold unsalted butter, cubed

Instructions:

  1. Preheat oven to 350°F (175°C). Grease a 9x5 inch loaf pan or line it with parchment paper.
  2. In a large bowl, whisk together the flour, baking soda, salt, and pumpkin pie spice until fully combined.
  3. Beat the vegetable oil and granulated sugar until smooth.
  4. Add the eggs one at a time, then stir in the pumpkin purée and vanilla extract.
  5. Gently fold in the dry ingredients using a spatula. Stir only until no streaks of flour remain.
  6. In a small bowl, combine the streusel flour, brown sugar, and cinnamon.
  7. Using a fork or fingertips, work the cold butter into the streusel mixture until it forms pea-sized crumbs.
  8. Pour the batter into the prepared pan and sprinkle the streusel evenly over the top.
  9. Bake for 50–55 minutes until a toothpick inserted in the center comes out clean and the topping is mahogany brown.
  10. Let the cake cool in the pan for 10 minutes before transferring to a wire rack.
