While I would love for you to try my recipes and be able to meet your dietary needs as well, unfortunately any substitution of primary ingredients like butter, eggs, or flour will drastically alter the baking chemistry here and likely and compromise the results. So while you are always welcome to experiment, and I love to hear how it goes when you do, I have not been able to test all those substitutions so I can't recommend them. I find you will always have better results when baking up treats designed with say vegan butter sticks, flax seed eggs, or almond flour from the start. And luckily, Google can help you find many of my fellow bloggers with delicious recipes in those specialty diet niches!
