Rolled oats: can be subbed for quick oats, if you are using quick oats they will not need to be soaked as long, 10 minutes will be ok, not overnight
Butter: A mild flavoured oil, ie not extra virgin olive oil as this will be too strong
Flour: Plain flour can be subbed for wholemeal four (this will give a denser muffin) or gluten-free flour, but not a nut flour like almond four or coconut flour
Milk: Can be substituted for any milk alternative; Soy, Almond, Rice etc
Brown Sugar: I use brown sugar in this recipe because I like the flavour it gives but this can be substituted for any granulated sugar.
Raisins:These can be subbed for another dried fruit, dates work well. Just cut them into pieces similar in size to raisins.
Egg:This recipe will work with ¼ cup of apple sauce as an egg replacer.
