This granola is insanely indulgent, and makes a great gift!
Preheat the oven to 325 degrees. Line a baking sheet with parchment paper.
Combine the oats, crispy rice cereal, hazelnuts, and coconut in a large bowl.
Combine the oil, sugar, honey or maple syrup, hazelnut liquor (if using), and salt in a small saucepan. Heat over medium heat, stirring, until the sugar is dissolved. Pour over the oat mixture and toss to coat evenly.
Spread the granola on the prepared baking sheet and bake for 25 to 30 minutes, until it is toasted and golden-brown. Do not stir! (Check the granola after 20 minutes, and if it seems to be browning quickly, turn the oven down to 300.)
Let the granola cool completely, then break it into chunks and stir in the chocolate.
If you can't find blanched hazelnuts (I got mine at Costco), you can toast skin-on hazelnuts and then rub them in a clean kitchen towel. The skins should (mostly) come off.
