Preheat oven to 300 degrees F (150 C). Line a large baking sheet with parchment or lightly grease.
In a large bowl, combine flour, salt, and baking soda. Mix in coconut milk and milk using your hands. Clean and oil hands, then knead for 5 minutes to form a smooth dough. It will still be a little wet.
Divide the dough into 4 equal pieces. Roll each piece into a ball and place on prepared baking sheet. Flatten each ball into a 6 inch circle. Cover each piece with coconut flakes, if using.
Bake in preheated oven until toothpick inserted in center comes out clean, about 15 minutes. The bread will still be pale.
Remove to wire rack to let cool. Once cooled, place bake on baking sheet and broil or toast until tops are golden.
Serve day it is made.
