Preheat the oven to 180°C. Put 12 silicon muffin cases on a baking sheet or line a muffin tin with paper cases.
Scrape the sweet potato flesh from the skin and measure out 1 cupful into a mixing bowl. Add the oil, almond milk, maple syrup and eggs, then combine ( it should remain a bit lumpy).
In another bowl, mix the dry ingredients together, then add this to the sweet potato mixture. Combine gently then spoon it into the muffin cases.
Bake the muffins for 25-30 minutes until a skewer inserted into the middle of a muffin comes out clean.
Let them cool on a wire-rack before serving.
