Buckwheat cookies with coffee and walnuts

Shortbread cookies are one of my favourites. Because they are very easy and quick to make. I often make shortbread when my friends come or when I cook with the kids. I have a few basic recipes but today I was experimenting with buckwheat flour and I loved the result. These shortbreads are very comforting with a hint of coffee and walnuts. I loved this combination with a delicious flavour of buckwheat flour. It has quite specific flavour so I use 50/50 with plain flour.

Buckwheat shortbreads with coffee and walnuts

210 g plain flour
 180 g butter, softened
 30 g icing sugar
 1 egg
 2 tbsp ground coffee
 1/2 cup chopped walnuts
 pinch of salt

Preheat the oven to 175C.
Sift the flour onto the working surface. Rub in the cold butter using your fingertips until crumbs. Beat the egg with the icing sugar and pour into the dry mix. Add coffee and walnuts. Knead a soft, elastic dough. Try to do it quickly because it become sticky and soft. Cover it with the cling film and place in the fridge for 40-50 minutes. You can keep the dough up to 3 days in the fridge.
Roll the dough out and cut cookie shapes. I used Christmas tree cookie cutters. Arrange the shortbreads onto the baking tray lined with baking paper and bake for 10 minutes until slightly golden. Let them cool.
