Pre-heat the oven to 180C/350F degrees
Place the almond flour, baking powder, psyllium husk powder, flax-seed flour and salt in a bowl and mix thoroughly.
Add the olive oil and eggs and blend well until the mixture looks like breadcrumbs.
Add the apple cider vinegar and mix well.
Gently add the water, a bit at time and stir into the mixture (you may not need it all if it looks too wet).
Let the mixture stand for 30 minutes to firm up.
Line a baking tray with parchment paper.
Using your hands, make a ball of the dough (I find keeping my hands wet helps with the sticky dough).
Place the balls on a parchment paper lined baking tray.
Bake for 30 minutes until golden and firm.
Eat and enjoy!
