Crust – Preheat the oven to 350 F. Spray the 9x9 inch baking pan or line with parchment paper. Put softened butter in a medium dish and mix at medium speed for about a minute, then add vanilla, a pinch of salt and flour and mix until well combined. Finally add walnuts or pecans and stir. Spread evenly in a prepared dish and press lightly using your hands or some firm object. Bake for 15 minutes. Leave to cool completely.
