Heat oven to 350°Fahrenheit/175°Celsius. Grease an 8x8-inch baking pan and line it with parchment paper. Make sure it overhangs the edges so it's easier to lift the cake out later!
In a large bowl, whisk together pumpkin puree, vegetable oil, sugar, eggs, and vanilla until smooth. Add the baking powder, baking soda, spices, and salt. Mix until completely combined. Add flour and stir, stopping when you no longer see streaks of flour.

Pour into your prepared pan. In a small bowl, whisk together the extra sugar and pumpkin pie spice - this is totally optional! Feel free to skip this step if you don't want to sugar topping. Sprinkle over the cake.

Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted comes out clean.

Notes
My recipes have been developed and tested in cups and metric grams. I highly recommend using a weighing scale and measuring out your ingredients the metric way
Neutral Oil: Use an oil like vegetable, canola, or sunflower oil. We want something without a strong taste!
Pumpkin Puree: Make sure you're using 100% pure pumpkin puree and not pumpkin pie filling.
Storage: Keep tightly wrapped at room temperature for up to 5 days.
