1-Preheat your oven: Preheat your oven to 350°F (175°C). Grease and flour a 9-inch round cake pan or line it with parchment paper to ensure easy removal.

2-Combine dry ingredients: In a large bowl, whisk together all-purpose flour, baking soda, cinnamon, nutmeg, and salt until evenly combined.

3-Combine wet ingredients: In a separate bowl, beat the eggs and then add sugar, pumpkin puree, and vegetable oil. Mix thoroughly to create a smooth batter.

4-Mix wet and dry ingredients: Gradually add the dry ingredients into the wet ingredients, stirring gently until just combined. Avoid overmixing to maintain a light texture.

5-Adaptations: For vegan or gluten-free adaptations, replace eggs with flaxseed mixture and use gluten-free flour blend respectively, ensuring the batter remains smooth.

6-Prepare for baking: Pour the batter into the prepared cake pan, smoothing the top with a spatula.

7-Bake the cake: Bake in the preheated oven for 45-50 minutes or until a toothpick inserted into the center comes out clean.

8-Cool and decorate: Remove the cake from the oven and let it cool in the pan for 10 minutes before transferring onto a wire rack to cool completely. Once cooled, decorate as desired and serve.
