Why you're going to love this recipe
There is no way you couldn't convince kids to eat these. They are the perfect cookie. Any questions about the "stringy stuff" and tell them it's coconut. Seriously. Nobody needs to know there are veggies in there. It can be our little secret. Zucchini is one of the easiest veggies to smuggle, like in these chocolate zucchini muffins, or these apple zucchini muffins.
Here are the other reasons you will love them:
- freezer friendly
- veggie smuggling
- easy to make
- one bowl mixing
- they don't taste like zucchini
What goes into the recipe
- brown sugar- when I first tried making these cookies, I really really did try to make them without sugar. But they were bitter and not great. The compromise is this small amount of sugar that helps them to be super kid friendly.
- zucchini- the zucchinis for this recipe weigh between 180 and 200 grams. Zucchini is high in fibre and low in calories. It also contains a high concentration of Vitamin B6, which helps with blood sugar regulation. Zucchini is also an excellent source of Vitamin C, manganese and Vitamin A (beta-carotene!).
- chocolate chips- choose dark chocolate chips. They hold up better and they actually contain more cacao than milk chocolate chips which have a lot more sugar in them.
- wholemeal flour- might as well try and get some wholegrains in where you can! If you don't have wholemeal flour you can just use plain white flour, no problems.
- butter- if you are trying to make these dairy free you can swap for coocnut oil.
- milk- for a dairy free option try rice milk for these chocolate zucchini cookies, because they need to stay nut free for lunchboxes.
- rolled oats- these are in there for texture, you can swap for quinoa flakes if you prefer.
