Peanut butter cookies

I made these cookies this afternoon. The recipe is from a little book I bought in the UK called simply 'Cakes'. I used to make these back in the days when G and I worked in a call centre together for our team to enjoy while working the 10 hour shifts! (But we had lots of days off as a consequence of the long hours which was great for travelling around the country!).

125g butter, softened
150g crunchy peanut butter (I use Ceres Organic)
225g granulated sugar
1 egg, lightly beaten
150g plain flour
1/2 tsp baking powder
pinch of salt
75g unsalted peanuts, chopped

Beat butter and peanut butter together in a large bowl.
Add the sugar and beat well.
Gradually add the beaten egg, beating well between each addition.
Sift in the flour, baking powder and salt. Mix well. Add chopped peanuts. Refrigerate mixture wrapped in plastic wrap for 30 mins.
Roll golf ball sized balls out of mixture and flatten slightly, place on baking paper lined trays. Leave at least 3cms space between cookies to allow for mixture to spread. Bake for about 12-15 mins at 190 deg C or until golden brown. Remove from oven and then cool on wire racks.
These cookies are crisp and full of peanut flavour and went down very well today with a nice cup of tea!
