Gatnabour (Armenian butter and flour cake)

Instructions

1. Preheat the oven to 180 °C and butter a round tin about 24 cm across.
2. Mix the flour, baking powder, salt and sugar, then rub in the cold butter with your fingertips until it looks like sand.
3. Add the eggs, vanilla and milk, and bring together just enough to form a smooth dough, without kneading it for long.
4. Divide the dough in two, press the first half over the base of the tin and set the second half aside.
5. Mix the crushed walnuts with the filling sugar and cinnamon, then spread over the dough, leaving a 2 cm border.
6. Drizzle with the melted butter, cover with the second half of dough rolled into a disc and seal the edges.
7. Brush the top with egg yolk, prick the surface with a fork and bake for 35 minutes until golden brown.
8. Let it cool slightly, dust with icing sugar and cut into slices to serve.
