Preheat the oven to 375 degrees.
Place the flour, baking soda, and salt in a large food processor (9 cup or larger capacity) with the dough blade. Mix briefly. Chop the coconut oil into small pieces and add it to the flour mixture. Process until the mixture has a crumb-like texture. Scrape down the sides a few times between pulses.
In a large bowl, combine the coconut milk, eggs, and maple syrup. Add this to the food processor and process until the dough starts to come together. It should be sticky, but you should be able to handle it. Add a few more tablespoons of flour if it’s too sticky to handle.
Place the dough in the large bowl and add the raisins. Mix the raisins into the dough with your hands.
Form the dough into a loose ball and press down slightly. Place it in a large cast iron skillet. Use a sharp knife to score the dough, placing an "x" across the top (about 1/2 inch deep).
Bake the loaf for 45 minutes, or until nicely browned and a toothpick inserted in the center comes out clean.
