1. Preheat oven to 350ºF. Line a 9-inch square baking pan with parchment paper.
2. In a small bowl, combine almond flour, arrowroot, cocoa powder, baking soda and salt. In a large bowl, whisk together sugar, maple syrup, butter, egg and 2 tsp water. In a small cup, combine espresso and vanilla; stir until espresso dissolves. Stir espresso mixture into butter mixture. Fold in flour mixture, then chocolate and hazelnuts. Transfer to prepared pan and spread evenly.
3. Bake for 18 to 20 minutes, until cracking around edges but still soft in the middle. Set aside to cool, then cover and refrigerate for at least 1 hour before cutting into 16 squares. Store leftovers covered in the fridge.
