Step 1

Preheat the oven to 320F (160C) and line a baking tray with greaseproof paper.

Step 2

Make the flax eggs: add the ground flax seeds and water to a small bowl and stir. Let it rest for 5-10 minutes to thicken (see notes 5 and 6).

Step 3

In a bowl, mix all the dry ingredients: ground almond flour, baking powder, sugar, and cocoa powder, then add the flax eggs.

Step 4

Stir together until combined. It might look like you need to add more water but keep mixing, and if necessary, use your hands. The mixture needs to become like a thick paste that you can roll into sticky balls in your hands.

Step 5

Using a tablespoon, scoop out a bit of a mixture and roll into a ball. Toss each ball into the icing sugar, coating entirely.

Step 6

Place each ball onto the baking tray and gently press it with the palm of your hand to squash it down slightly. Repeat with the remaining dough (you should be able to make 15 cookies).

Step 7

Bake for 10 minutes. Remove from the oven (note and let them cool down before serving.
