Keep the base recipe the same, and just change your add-ins and flavoring. Try: Almond extract with sliced almonds and cashew pieces Banana flavoring with banana chip bits and sliced almonds Blueberry flavoring with dried blueberries and ground hazelnuts(posted 9654 days ago)Or replace the WW flour with oat bran, wheat bran, or wheat germ. Or add cheap cereals like cornflakes or rice crispies to extend it a la Honey-Bunches of Oats.
It's best if you can try to find a cheap source of dried fruits and nuts. I love dried cherries and hazelnuts, but they're pretty cheap in MI. It would cost more for coconut or pecans.
