Start by preheating your oven to 350°F.

Place the hazelnuts in the oven and roast them for approximately 5 minutes. Then allow them to cool off and use your hands to remove the skin.

Process the hazelnuts in a food processor until finely chopped.

In a microwavable bowl, combine Nutella and butter, and microwave for about 30 seconds or until the butter has melted. Stir until well combined.

Add powdered sugar to the Nutella mixture and mix again.

In another bowl, melt the chocolate chips in the microwave for about 2 minutes, stirring every 30 seconds until fully melted.

Coat your candy mold completely with the melted chocolate, ensuring all the holes are covered. Then flip the mold over and let the excess chocolate drip out. Use a scraper to remove any remaining excess chocolate.

Cool the chocolate mold in the fridge for about 10 minutes or until slightly hardened.

Add the roasted hazelnuts to the mold.

Spoon the Nutella mixture into the mold, leaving room for more chocolate.

Pour the remaining melted chocolate over the candy molds, making sure they are fully covered. Tap the mold on the table a few times to remove air bubbles and ensure the chocolate settles at the bottom.

Use a metal scraper to remove any excess chocolate from the mold again.

Place the candies in the fridge for at least 30 minutes or until hardened.

Once hardened, remove the chocolates from the mold and enjoy!
