I recently bought a bread maker as I was fed up with the garbage sold in CM. Anyhoo, had three efforts already at “healthy” bread and while each tasted great, they completely collapsed during the rise cycle. I suspect it is because I am adding too many grains combined with whole wheat flour (although I did try and balance it up with proportions of white flour).
On another recipe I followed it to the letter which included one cup of multigrain cereal and that collapsed as well, but it still tasted good.
I have have been reading a lot on it and believe I may need to add Vital Wheat Gluten to my whole wheat grain recipes for my next effort.
I realise it’s a learning curve, but any input would help.
