If you are looking to lower the net carb count in these healthy apple crisp bars, you could remove the honey crisp apples and use zucchini only. Zucchini is a sneaky ingredient, and once we peel it, core it and cut it into bite sized chunks, it has a very neutral flavor, lending it very nicely to being disguised as an "apple". Once we add in our cinnamon and apple pie spice, along with some apple extract, butter, apple cider vinegar and sweetener, you could fool some serious apple enthusiasts! Since we are more on the low carb end of the spectrum, we really enjoy adding in actual apple to this recipe, but we understand if you are less than enthusiastic. We can replace the one large honey crisp apple in our recipe with one additional chopped, cored and peeled zucchini. This simple swap lowers the net carb count from 6 net carbs in the apple version, to 4 net carbs in the zucchini only version, making them keto apple crumble bars!
