Preheat oven to 180 °C / 355 °F. Line baking tray with baking paper.
In a pan heat 50 g (about 3-4 tbs) of honey until the honey becomes quite liquid. Remove from heat and add cacao powder. Combine well, then add puffed rice and coat with the cacao and honey mixture. Spread the cacao-coated puffed rice onto the baking paper and set aside to cool down.
In a large bowl combine rolled oats, pinch of salt, vanilla extract, flaked almonds, and roughly chopped toasted hazelnuts. Heat the remaining 50 g honey to turn it liquid, then slowly pour over the oats, stirring it well into the oats mixture. Make sure to combine ingredients well.
Spread the granola mix evenly on two baking trays lined with baking paper. Put in the oven and bake for about 15 minutes, stirring it occasionally to give it an even toast. Then, mix in the cacao-coated puffed rice and bake for another 10 minutes. Remove from oven and set aside to cool. When cooled, mix in finely chopped dark chocolate bits.
