# Steps to Follow:

01 - Preheat oven to 350°F (175°C). Grease and flour a 9×13-inch baking dish or bundt pan.
02 - In a large bowl, beat softened butter and sugar together until light and fluffy, about 2–3 minutes. Scrape sides as needed.
03 - Add eggs one at a time, mixing well after each addition.
04 - Stir in mashed sweet potatoes, sour cream, milk, and vanilla extract until smooth.
05 - In a separate bowl, whisk together flour, baking powder, baking soda, salt, cinnamon, and nutmeg.
06 - Gradually add dry ingredients to wet ingredients, stirring gently until just combined. Avoid overmixing.
07 - Pour batter into prepared pan and smooth top with a spatula.
08 - Bake in a 9×13-inch pan for 40–45 minutes or in a bundt pan for 50–60 minutes, until a toothpick inserted in the center comes out clean.
09 - Let cake cool in the pan for 15 minutes, then transfer to a wire rack to cool completely.
10 - For the glaze, melt butter in a small saucepan. Whisk in powdered sugar, milk, and vanilla extract until smooth. Drizzle over cooled cake.
11 - Slice and serve.

# Additional Notes:

01 - For best results, use room temperature ingredients.
02 - The glaze is optional but adds a nice finish to the cake.
03 - Store leftovers in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
