Tips

Tip 1

Make sure sweet potatoes are completely smooth when mashed to avoid lumps in the finished cake.

Tip 2

Use a dark or nonstick pan at 325°F instead of 350°F to prevent over-browning on the bottom.

Tip 3

Save leftover mashed sweet potato for another recipe since you'll only need 1 1/2 cups for this cake.
