Preheat oven to 350 and spray an 8×8 pan and set aside. Blend cashews and water until smooth. Add next 7 ingredients and blend again. Add this mixture to flour and baking powder. Stir well and then fold in nuts. Pour into pan and bake 35-40 minutes. You can frost these by melting 1-1/2 cups carob chips for 1 minute in the microwave, then spread over the top and sprinkle with nuts if desired.
