In a large bowl, cream together the butter, brown sugar, white sugar and peanut butter until smooth. Beat in the egg and vanilla. Combine the flour, wholemeal flour, bicarb soda and salt; stir into the peanut butter mixture. Finally, mix in the oats and chocolate chips. Drop by rounded spoonfuls onto ungreased baking trays.
Bake for 8 minutes in the preheated oven, or until edges are golden. Remove from baking trays to cool on wire racks.
These cookies are delicious. I used 100gm of peanut butter instead of the whole 190gm. They are soft and chewy in the middle and crunchy brown on the outside. Easy to make, and the recipe made almost 50 average sized cookies. - 20 Sep 2013
