Preheat oven to 375 degrees F. Spray or light brush a baking pan with oil. Set aside.
Peel cassava and cut into small chunks. Add cassava chunks to a high-speed blender, add coconut milk, vanilla, and almond extract. Process until cassava looks crumbly but not smooth.
In a large bowl, combine flour, coconut flakes, sugar, baking powder, cinnamon, nutmeg, ginger and salt.
Add the cassava mixture and stir to combine. Dust raisins with flour and fold into batter.
Transfer the batter to a prepared pan and bake for about 1 hour. Cool completely and serve.
