Start by peeling and chopping the sweet potatoes, then boil them until tender.

Preheat your oven to 350°F (175°C).

In a large mixing bowl, whisk together the mashed sweet potatoes, sugar, vegetable oil, and eggs until smooth.

In another bowl, sift together the flour, baking powder, baking soda, cinnamon, nutmeg, and salt.

Gradually add the dry ingredients to the wet mixture, stirring gently until just combined.

Grease your cake pans and line the bottoms with parchment paper.

Pour the batter evenly into the prepared pans and smooth the tops.

Bake for 25 to 30 minutes, or until a toothpick inserted in the center comes out clean.

Once baked, remove the cakes from the oven and let them cool in the pans for about 10 minutes.

Transfer them to a cooling rack to cool completely.
