Preheat the oven to 160 Deg C.
Line a 9*5 inch loaf pan with parchment paper.
In the meantime, in a wide bowl add in the chia seeds, flax meal and flax seeds.
Add lukewarm water and give everything a mix.
Let this rest for 5 minutes. The seeds will absorb moisture and become gel-like.
Now add in the remaining ingredients mix everything nicely. Be sure to check the bottom of the bowl, as sometimes dry ingredients remain in the bottom.
Once mixed, pour the batter in the prepared loaf pan.
Flatten the top with the back of a spatula.
Bake in a preheated oven for 1 hour.
After 1 hour increase the temperature to 180 Deg C and bake again for 10 minutes. (Check notes)
Remove and let it cool completely in the loaf pan itself on a wire rack.
Cut the slices when cooled completely.
