I usually cook these at Christmas time only, but found a packet of hazelnuts in the cupboard and thought they'd be a really nice treat for everyone.
First day of Winter tomorrow, so it will be nice to snuggle up with a hot cup of tea/hot milo and a couple of these.
They are easy to make - simply melt some chocolate and lightly cover the bottom of the patty cake shell (I use mini patty cake shells). Once the chocolate has set add a small half teaspoon (approx.) of nutella. Push a hazelnut into the middle of the nutella. Melt more chocolate and pour over the top. Sprinkle with icing sugar.
