Scroggin Lunch Biscuits

200g butter
1/4 cup peanut butter
1/2 cup sugar
1 cup (packed) brown sugar
2 large eggs
1 tsp vanilla or almond essence
1 1/2 cups plain flour*
1 tsp baking soda
2 cups rolled oats
1 cup chocolate chips
1 cup sultanas
1/2 cup chopped walnuts

*Use 1/4 cup less flour if using instant rolled oats.

Heat oven to 180C. Mix the softened butter and the next five ingredients together in a large bowl, then stir in the flour and baking soda. Add everything else and mix, using a wooden spoon or your hand.

Shape with two spoons or put flattened rounds of mixture on baking-paper lined trays, leaving space for spreading. Bake in batches for about 12 minutes or until lightly browned then cool on a rack.
