Biscuit
Mash the yolks and beat together with the butter. This is more easily done in a food processor if you have one.

Add the sour cream and sugar, mix well. Combine the baking powder with the flour and add to the mix. Combine well into a dough.

Take small balls of dough and push a whole hazelnut into the centre. Encase the hazelnut in the dough and shape into a ball the size of a walnut.

Place each ball of dough onto a well greased cooking tray.

Cook's Tip: If you don't like nuts you can leave them out altogether.

Preheat the oven to 150 degrees C. Bake the biscuits for 20 to 25 minutes or until lightly golden. Remove the biscuits from the oven when cooked and allow to cool.

Glaze
Melt the butter in a medium sized saucepan then add the sugar, cocoa and milk. Stir to combine and bring to the boil. Simmer, stirring continuously until the sugar has completely dissolved, then remove from the heat.

Dip each biscuit into the chocolate and coat fully before removing and rolling in the ground nuts or biscuit crumbs. Set aside to harden.

Serving
Makes approximately 30-40 biscuits.
