Preheat oven to 350 degrees F (180 C) and grease a 9x11 inch pan with a light amount of oil. In a medium mixing bowl, combine flaxmeal, chia, almond milk, and coconut milk. Add the melted coconut oil, salt, soda, cinnamon, vanilla, maple syrup, and sugar. Mix in the flour well and then gently fold in 1 1/2 cups of the blackberries. Measure out about 1/3 cup of the batter and pour the rest into the prepared pan.
