Ingredients:
- 14 oz sweetened condensed milk
- 12 oz semi-sweet chocolate chips
- 0.5 cup Nutella (hazelnut spread)
- 1 tsp pure vanilla extract
- 0.25 tsp sea salt
- 0.5 cup chopped toasted hazelnuts
Instructions:
- Line an 8x8 inch square baking pan with parchment paper, leaving an overhang on the sides to act as a sling for easy removal.
- In a medium heat-proof glass bowl, combine the semi-sweet chocolate chips and Nutella.
- Place the bowl over a saucepan of simmering water (double boiler method) or microwave in 30-second intervals, stirring between each, until the mixture is completely melted and glossy.
- Remove from heat and stir in the sweetened condensed milk, vanilla extract, and sea salt until the mixture is thick and unified.
- Fold in the chopped toasted hazelnuts if using.
- Spread the mixture evenly into the prepared pan, smoothing the top with a silicone spatula.
- Refrigerate for at least 3 hours until firm before lifting from the pan and slicing into 24 squares.
