Preparation
  1. Preheat your oven to 350°F (175°C) and prepare a 9x13 inch baking pan.
  2. In a bowl, whisk together the dry cake ingredients: flour, baking powder, baking soda, cinnamon, ginger, nutmeg, and salt.
  3. In a separate bowl, cream softened butter with granulated and brown sugars until light and fluffy; then beat in eggs one at a time, followed by vanilla extract.
  4. Combine pumpkin puree and buttermilk in another bowl.
  5. Gradually add the dry ingredients alternately with the pumpkin mixture to the butter mixture, starting and ending with dry ingredients, mixing just until combined.
  6. Pour the cake batter into the prepared pan and spread it evenly.
  7. For the crumble topping, combine flour, brown sugar, and cinnamon, then cut in cold cubed butter until coarse crumbs form.
  8. Sprinkle the crumble mixture evenly over the cake batter.
  9. Bake for 40-45 minutes, or until a toothpick inserted into the center comes out clean.
  10. Allow the cake to cool completely on a wire rack before serving.
