"Terrible recipe. One star. I substituted stevia for the sugar and mashed banana for the oil, and used almond shavings instead of chocolate chips and they look nothing like your picture."
That being said, I am getting braver about making my own substitions in baking recipes. I figure even if cookies end up too puffy or crumbly, or cupcakes collapse a little, things would have to be pretty bad before my kids would refuse to eat them.
Yesterday M wanted to make cookies by himself, and I thought of that old 3 ingredient peanut butter cookie recipe. He could make it with sunflower seed butter easily enough. The only problem was, we didn't have any sugar. Two minutes in, it was pretty obvious that honey (our go-to sweetener) wasn't going to work as a substitute this time. Luckily a little gf flour turned things around, and he turned out two batches within a half-hour: one plain, one with chocolate chips.
