Oat and nut biscuits recipe

This is my recipe for the oat and nut biscuits that I sometimes make for walks.

250g unsalted butter
200g rolled oats (can blitz to make oatmeal if you prefer)
125g chopped nuts
100g plain flour
75g caster sugar
1 teaspoon salt
half teaspoon bicarbonate of soda

Melt the butter.
Mix all the ingredients together and pat or roll them down on a large board to 8-10mm thickness.
Cut out biscuits to the size you want and place on greaseproof paper/baking parchment on a baking tray.
Bake at 150C for 25 minutes until pale golden.
Allow to cool - once they have solidified place them on a rack.

Philippa makes thinner biscuits without the nuts (substitute more oats), and dips half in chocolate.
