Line a loaf pan with parchment paper and oil it with coconut oil.
Make your flax egg by mixing 1 tbsp flaxseed meal with 3 tbsp water. Let the mixture thicken for 5 minutes.
Meanwhile, preheat the oven to 350F.
In a large bowl, whisk together the all-purpose flour, buckwheat flour, baking powder, baking soda, chia seeds and salt.
In another bowl, mix together the mashed bananas, flax egg, melted coconut oil, coconut yogurt, coconut sugar, vanilla extract and almond milk.
Pour the wet mixture into the flour mix and stir well to combine. Add in the berries and mix gently until they are evenly dispersed.
Pour the batter into the loaf pan and decorate with more berries and coconut chips.
Bake for 50 minutes to an hour.
Cool for 15 minutes before enjoying.
