Nut Slices with Egg Yolk Glaze

Preheat the oven to 160 °C top/bottom heat. Line a baking sheet with baking paper.

Cream the soft butter with the powdered sugar until fluffy. Stir in the plain flour and the finely grated walnuts. Beat the egg whites until stiff and carefully fold them into the mixture.

Spread the dough evenly on the prepared baking sheet and smooth it out. Bake in the preheated oven for approx. 30–35 minutes until golden brown.
