Soak unroasted buckwheat groats for at least 6 hours or overnight.
Mix chia seeds with 180 grams of water. Set it aside for about 10 to 15 minutes. You'll get jelly consistency mass.
Drain soaked buckwheat groats. Add half drained groats and all other ingredients into your blender or food processor. Blend till everything is combined, but don't overmix. Then add another half of buckwheat groats and mix it a little bit. (Your dough does not have to be silky smooth consistency).
Preheat your oven to 160°C, while the oven is heating up, grease your loaf pan and line it with parchment paper.
Pour the dough into the loaf pan, then a few times lightly knock it into the hard surface, so that air bubbles could come out of the dough. Sprinkle some toppings, like seeds, nuts, or spices.
Place your bread into the oven and bake it for 1 hour and 20 minutes. Then take it out and let it cool down completely before slicing it. That's it, now - enjoy!
