Toppings I used: Chopped walnuts or pecans, chopped fresh or dried apples
Variations: Use yogurt in place of some or all of the milk. Personally, I find that if I use all yogurt, I will need a touch of liquid added just before serving to the get texture I like. I am also not as fond of heating the overnight oats mixture if it has yogurt in it. For a truly decadent variation, use heavy cream.
You can substitute other fruits such as cherries, peaches, or pears for the apples. Using dried fruits means that you have no further prep in the morning. If using fresh, it will require some chopping just before serving.
Try variations of other nuts with your overnight oats. Almonds are another fantastic option but you can head outside the box with some cashews or macadamia nuts too. I often like to throw some raisins and/or dried cranberries into this recipe as well. YUM!
