Things You'll Need

  • 5 sweet potatoes (about 5 cups cooked and mashed)

  • 1 stick (1/2 cup) butter, melted

  • 1 cup brown sugar

  • 5 large eggs

  • 1/2 cup half & half or heavy cream

  • 2 tsp pure vanilla extract

  • 2 tsp ground cinnamon

  • 1/2 tsp ground nutmeg

  • 1/2 tsp sea salt

Tip

Make recipe dairy-free by replacing the butter with vegan "butter" spread and the half & half for full-fat canned coconut milk.

Step 1

Place sweet potatoes in a large pot and cover with water. Cover and bring to a full boil. Boil potatoes for 15 to 20 minutes, until potatoes are very tender when poked with a fork.

Transfer the sweet potatoes to a cutting board and allow them to cool completely. Once cool enough to handle, remove the skins from the sweet potatoes and discard.
