Pre heat oven to 350 degrees and grease a 8×8 inch square baking dish

Combine everything but chocolate chips, walnuts and peanut butter in a food processor and blend till smooth and full combined then stir in chocolate chips and walnuts if adding in

Spread mixture in prepared baking dish and swirl in peanut butter with a butter knife if adding and sprinkle on extra chocolate chips and bake for 20 minutes.

Let cool for at least 20 minutes before eatting. I'll spread the chocolate chips out over the brownies then store rest covered in the refrigerator.

Very good served with a dollop of whipped cream or vanilla ice cream and chocolate syrup
