Bake the granola
Place the buckwheat, linseed, nuts and pumpkin seeds in a large bowl. Stir in the cinnamon, matcha, coconut oil and apple puree. Thinly spread all the ingredients over an oven tray lined with baking paper, to a depth of approx. 1 cm.
Bake for approx. 30 mins. in the centre of an oven preheated to 150°C, shaking halfway through cooking. Remove from the oven, leave to cool.
Finely chop all the fruits in a food processor, add to the cooled mixture and mix everything together well.
