In a large bowl combine the oats, buckwheat, coconut flakes, hazelnuts, seeds, sea salt, vanilla powder and coconut sugar and stir to combine.
Melt the coconut oil in a small saucepan over medium to low heat, then add the honey and cacao powder. Whisk until smooth.
Pour the liquid over the dry ingredients and mix until evenly coated.
Line a baking sheet with wax-proof paper then turn the mixture out and press evenly and firmly into the baking sheet using the back of a spoon until it is compact.
Bake for 18 minutes then remove from the oven and using a spatula, flip the granola. Return to the oven and bake for a further 12 minutes, stirring every 3 minutes until the granola is toasted, then remove from the oven and allow to cool.
Store in an airtight container.
