I used to have a difficult time with vegan baking until I looked for replacements for eggs. I personally can’t use egg replacer (and healthier options exist). I mostly use flax, chia or banana and pumpkin in my baking. I find them to be more nutritious and I love the flavour they give.
If you are looking for help with a dish that is mostly eggs like a scramble, omelette or quiche, these can be made with tofu and nutritional yeast. In a previous post you will find a tofu scramble recipe.
