Recipe Notes

If you'd like to make this recipe a little healthier for whatever reason, you can substitute some of the ingredients:

You can omit the peanut butter if you like, it is not an essential. 


I use a 1:1 ratio for the flour and oats, meaning equal amounts. However, many lactation cookie recipes use 2 cups flour and 3 cups of oats. I find that it makes the cookies rather dry, and prefer it this way. If you really want to up your milk supply, I  would definitely recommend going for the latter.
