substitutions
Rolled Oats: As we mentioned above, this is the only type of oats that we recommend using for this overnight oatmeal recipe. I have not tried this oatmeal recipe with quick cook oats. I think it may work, but they might get soggier quicker. I wouldn’t recommend it.
Irish/Steel Cut Oats will not work in this recipe. If you need a Steel Cut Oats recipe, check out this Baked Steel Cut Oatmeal!
For a gluten free overnight oatmeal recipe, be sure to use certified gluten free rolled oats.
Blended Oats: We love this Blended Baked Oats Recipe!
Greek Yogurt: Nonfat Greek yogurt is higher in protein and calcium than traditional yogurt, and it has a thicker consistency. If you want to use regular yogurt, we recommend vanilla or plain flavor nonfat yogurt.
Vanilla Protein Powder: Because this recipe is for overnight oats with protein powder, this ingredient is essential and shouldn’t be left out. For this healthy make ahead breakfast, we like to use vanilla protein powder. If you need a substitute, either unflavored or chocolate protein powder are good options. You can use whey powder, pea protein, or even collagen protein. For a dairy free or vegan breakfast, use vegan protein powder.
Milk: You can sub almond milk for any kind of milk (dairy, oat, rice, coconut milk, etc). Any kind will work!
Cinnamon: Is optional but really adds good flavor
Fruit: Any fruit will work in this recipe! We also love Mango Oats, Strawberry Oats, Blueberry Oats, Apple Cinnamon Oats, and Banana Oats.

Rob says
Enjoyed this recipe very much. Simple, healthy and delicious! I did have to add some honey to help sweeten it a little since I used fat free sugar free yogurt. Somewhere, I believe a video, and even in a picture above, it mentioned adding maple syrup. Is there a reason it’s no longer in the recipe?

It’s listed as optional because most protein powders are pretty sweet!
