Turn the oven on to 350°F (175°C). Lay the hazelnuts across a baking tray and roast them for 10–12 minutes, giving them a stir in between. Once they've cooled, chop them roughly. Keep ½ cup aside for sprinkling at the end.

Grab a medium bowl and whisk together the flour, baking powder, cocoa powder, and salt. In a larger bowl, cream together the butter, white sugar, and brown sugar until fluffy, about 2–3 minutes. Mix in the egg and vanilla until smooth. Slowly add the dry mix to the wet ingredients and stir until it’s all combined. Toss in those toasted hazelnuts and fold them into the mix.

Line a baking tray with either parchment paper or a silicone mat. Scoop out small bits of dough, about a tablespoon each, then roll them into balls. Lightly press them to turn them into discs. Bake for 10–12 minutes, just until the edges firm up. Cool completely on a rack before moving on.

Gently melt your chocolate with the coconut oil, if you’re using it, by microwaving in 30-second spurts. Stir in between until silky. Coat each cookie in the melted chocolate. Place them onto parchment paper or a wire rack, then sprinkle the saved hazelnuts on top while the chocolate’s still wet. Leave them to set either at room temperature or in the fridge to speed it along.
