Substitutions
Here are my recommended substitutions to make this overnight oats with protein if you need them.
- Oats: Heartier types of oats such as old fashioned, rolled oats or steel cut oats are better options for overnight oats. Quick cooking oats will become mushier than the other types of oats. If needed, use gluten free oats to make these overnight oatmeal gluten free.
- Chia Seeds: I like adding chia seeds to overnight oats for a thicker and creamier consistency. Feel free to omit or use flax seeds if you like.
- Milk: Use any milk you like. Plant based milk also works well in this recipe if you would like to make these protein overnight oats vegan. For an extra boost of protein, use protein milk.
- Yogurt: Use a good greek yogurt you like. If you would like to make this vegan, use a plant based yogurt.
- Peanut Butter: Feel free to use your preferred runny or creamy peanut butter. If you prefer not to use peanut butter, use any nut butter you like. Sunbutter is a good peanut butter alternative.
- Maple Syrup: Honey or agave work well to sweeten these protein oats.
- Vanilla Extract: This is for flavor. Feel free to omit if you don’t have any vanilla extract on hand.

- Add the milk, yogurt, peanut butter, maple syrup or honey and vanilla extract to a large mixing bowl. Whisk the mixture together until smooth and well combined.

- When it’s time to serve, top the peanut butter oats with your preferred toppings and enjoy. I love topping mine with warmed peanut butter, slices of bananas, a drizzle of honey and some mini chocolate chips.
How To Make Ahead, Store and Serve

M’s Expert Tips
- Mix the ingredients directly into individual containers. The easiest and more precise way to make overnight oats is to mix the dry and wet ingredients directly into the individual containers. If you prefer, mix the dry ingredients in the containers. Then mix the liquid ingredients in a large bowl until well combined. Evenly pour the liquid into the containers and chill.
- How to make it pretty. To create the layered look simply smear some pb on the sides of the glass container prior to mixing in the overnight oats.
- Use the right kind of oats. Rolled oats, old fashioned oats or steel cut oats are good for making overnight oats. Quick cooking oats are not ideal unless you prefer a mushier texture.
- Add chia or flax seeds. The addition of chia or flax seeds adds healthy omega-3 fats and creates a thicker more pudding like consistency to the pb overnight oats.
- Add toppings right before serving. Add a dollop of peanut butter, some sliced bananas or berries and a drizzle of honey right before serving.
FAQs
Yes, overnight oats have a whole host of benefits to keep your body healthy. Soaking the oats breaks down starches and phytic acid, making the nutrients and vitamins easier to absorb. The addition of chia seeds adds a boost of omega-3. Adding peanut butter or any other nut butter adds more satiating protein to keep you fuller for longer.
Scoop the amount of peanut butter you would like to add to the overnight oats either as a mix-in or as a topping, to a microwave safe dish. Heat the peanut butter for about 20 - 30 seconds or until the pb becomes more liquid.
