Preheat oven to 350 F/ 175 C
Cut the potatoes into cubes.
Put them in a pot and cover with water. Add a pinch of salt, and bring to a boil. Takes about 10 minutes.
Simmer another 10 minutes until potatoes are soft.
Drain and rinse with cold water to cool them down.
Add them to a bowl with the coconut milk, vanilla and salt.
Mash with a potato masher. I like to leave some chunks for texture, but you can mash until smooth.
Put into a square dish (9 x 9 or 8 x 8 works) and smooth out the top.
To make the toppings, put all ingredients into a food processor and blend until crumbly.
Pour the topping over the top of the sweet potato mixture.
Bake for 25 minutes.
Serve!
