Prepare a 9x9 inch pan by spraying it with nonstick cooking spray.
In a large mixing bowl, combine 2 cups of flour, ¾ cup of sugar, 2 tsp. of baking powder, ½ tsp. of salt, and 1 Tbsp. of pumpkin pie spice. Whisk until well combined.
Stir in 1 cup of pumpkin puree, ¼ cup of vegetable oil, 1 tsp. of vanilla extract, and ½ cup of milk until smooth.
Pour the batter into the prepared pan and smooth it out with a spatula.
In a small bowl, mix ¼ cup of melted butter, ¼ cup of flour, 1 cup of brown sugar, 1 Tbsp. of cinnamon, and a pinch of salt until crumbly.
Sprinkle the crumbly topping evenly over the pumpkin batter.
Bake in the preheated oven for 30-40 minutes. Check for doneness with a toothpick.
Allow the cake to cool before slicing and serving.
