Preheat the oven to 175°C (160°C fan) and line a baking tray with baking paper.
In a large bowl, combine the quinoa flakes, almond flour, coconut sugar, cacao powder, ground flaxseed, baking powder, bicarbonate of soda, cinnamon, ginger and salt.
In a separate bowl, whisk together the maple syrup, avocado oil, tahini or almond butter, almond extract and almond milk until smooth.
Pour the wet ingredients into the dry ingredients and mix until everything is well combined. Leave the mixture to sit for 3-5 minutes so the quinoa flakes and flaxseed can absorb some of the moisture.
Fold through the dark chocolate chips and chopped pecans, if using.
Scoop tablespoon-sized portions onto the lined baking tray and gently flatten each one. The cookies won't spread very much during baking.
Bake for 10-12 minutes, until the cookies are lightly golden around the edges.
Leave them on the baking tray for around 5 minutes before carefully transferring them to a cooling rack. They'll firm up and become crispier as they cool.
