Fill a large pot of salted water and bring to a boil. Poke holes in your sweet potatoes and add them to the boiling water and cook until tender (approx 40 mins). Once sweet potatoes are cooked, allow them to cool.
Once the sweet potatoes have cooled, peel them.
Add your eggs to a bowl and slightly beat them. Then add the sugar and stir.
Add the remaining filling ingredients - the sweet potatoes, butter, vanilla and salt. Mix to create the filling.
Pour the filling into a pan of your choice. I like to use a deep 9x9 pan, but it works in a 9x13 too.
