Thank you Lacey. I'm really pleased you're enjoying it!

You can use any type of sugar you like so coconut sugar would be fine. And maple syrup will work too.

Well, I have finally made the Apple Baked Oatmeal. I have mixed 200gs oats and only 50gs quinoa flakes and it appears the two didn’t hold evenly together. While the quinoa is lighter when dry it becomes heavier when mixed with milk and ends up in the bottom of the pan. However, it tastes lovely and I will make it again with just oatmeal and perhaps more walnuts.
Thanks for your advised not to use too much quinoa in the mixt. I'm not an experienced cook, only started cooking when became vegan so "the virtual vegan" recipes well explained are my favorites to try, Thanks again.

I wouldn't use almond flour. It will make it drier. Almond butter works as glue to hold it all together. Most almond butters just have one ingredient. Almonds. They don't have any oil added, so basically it's the same nutrition-wise as eating almond flour.
Hope that helps!

Thanks! And one more question: would almond flour possibly work in lieu of almond butter? Trying to avoid the oil that a lot of nut butters are made with.

I think flavour-wise it would be ok if you don't mind it being a little more apple-y. That's not necessarily a bad thing. It might affect the texture a little though because apple butter contains a lot of moisture. Nut butter acts a bit like glue and holds it together too so it might not slice as well.
If you're ok with that then go for it. Hope you enjoy it!
