Preparation
In a large bowl, whisk together the almond flour, ground flax, and cacao powder.
Add the melted coconut oil, water, sweetener, and vanilla extract.
Mix thoroughly until a sticky dough forms.
Fold in the chopped macadamia nuts until they are evenly distributed throughout the dough.
Scoop the mixture by the tablespoon, roll into balls, and then press flat between your palms to form cookie shapes.
Place the cookies on your dehydrator screens, leaving a little space between each one.
Dehydrate for 1 hour at 145°F / 63°C.
Reduce the heat to 116°F / 47°C and continue dehydrating for 5-7 hours, or until the cookies are firm on the outside and slightly chewy inside.
Add a pinch of sea salt or a 1/4 teaspoon (20 ml / 0.7 fl oz) of espresso powder to the dry to intensify the deep chocolate flavor.
