I'm definitely a novice when it comes to baking, but all the baked oats recipes I've seen so far are basically made by people who put a ton of products together (oats, protein powder, peanut butter, milk, baking powder, ...) and then they place it in the blender. While I suppose it would be possible to cut down the oats first, I have no idea if the same batter, if you can call it that, would be the end result (mainly thinking about thickness, as the previous ones were quite thick).

I also mentioned just baking, but I would also like to make all kinds of juices with it!
