Follow these steps, and soon your kitchen will be filled with the irresistible aroma of fresh-baked cake:

1. Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking pan.
2. In a large bowl, cream together the softened butter and sugar until light and fluffy. This should take about 3-4 minutes.
3. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.
4. In a separate bowl, whisk together the flour, baking powder, cinnamon, nutmeg, and salt.
5. Add the dry ingredients to the butter mixture alternately with the milk, starting and ending with the flour mixture. Mix until just combined.
6. Fold in the mashed sweet potatoes until the batter is smooth and well-blended.
7. Pour the batter into the prepared baking pan and smooth the top with a spatula.
8. Bake in the preheated oven for 50-60 minutes, or until a toothpick inserted into the center comes out clean.
9. Allow the cake to cool in the pan for about 15 minutes before transferring to a wire rack to cool completely.

During those busy evenings, I often found myself multitasking—helping with homework while mixing batter. Remember, the key is to enjoy the process as much as the final result.
