Melt the butter in the microwave and then pour into a mixing bowl. Add the Brown Sugar and Sugar and whisk until combined.

Add in the egg and egg yolk and then whisk until fluffy.

Add in the salt, vanilla extract, hazelnuts and chocolate chips and mix in evenly.

Sift in the plain flour and baking soda and fold in until you get a cookie dough consistency.

Use a medium sized ice cream scoop or measure 50g dough balls (3 tbsp) and create a well in the centre with the back of a spoon. Fill it with 1/2 tsp Hazelnut chocolate spread and then cover with the cookie dough.

Place onto a baking tray lined with baking paper and then place into the fridge to chill for at least 30 mins.

Spread on a little chocolate spread on the dough balls before baking.

Pre-heat the oven to 180°C and then place the baking tray into the oven for 11 mins. Be sure to space out the dough balls as they will spread in the oven.

Once baked, sprinkle on some chopped hazelnuts to garnish.

Allow the cookies to rest for a while before transferring them to a wire rack to cool fully (feel free to tuck in whilst they’re warm if you don’t want to wait!).
