Follow these easy steps to create your mouthwatering Pumpkin Cake:

1. Preheat Oven: Begin by preheating your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan.
2. Mix Dry Ingredients: In a medium bowl, whisk together the flour, baking powder, baking soda, cinnamon, nutmeg, and salt. Set aside.
3. Combine Sugars and Oil: In a large bowl, mix together the granulated sugar, brown sugar, and vegetable oil until well combined.
4. Add Eggs: Beat in the eggs, one at a time, ensuring each one is fully incorporated before adding the next.
5. Incorporate Pumpkin: Stir in the pumpkin puree and vanilla extract until smooth and creamy.
6. Combine Mixtures: Gradually add the dry ingredients to the pumpkin mixture, stirring gently until just combined. Be careful not to overmix.
7. Add Optional Ingredients: If desired, fold in chopped nuts or chocolate chips for added texture and flavor.
8. Pour Batter: Pour the batter into the prepared baking pan, smoothing the top with a spatula.
9. Bake: Place the pan in the preheated oven and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.
10. Cool: Once baked, remove the cake from the oven and allow it to cool in the pan for 15-20 minutes. Then, transfer it to a wire rack to cool completely.
