Ingredients and substitutions:
- Rolled oats: rolled oats absorb more liquid than other oats, while still holding their shape nicely so they are the best oats for overnight oats. I use sprouted rolled oats which are certified glyphosate free and gluten-free. Be sure to use rolled oats and not quick oats or steel cut oats for this recipe.
- Milk: use any milk that you like. I like to use coconut milk because it has a perfectly creamy, rich texture but you can use other milks such as almond milk, cashew milk, oat milk, or soy milk.
- Nut butter: I prefer to use peanut butter, almond butter or cashew butter for this overnight oats recipe but you can use any nut butter or seed butter that you like. Be sure to use unsweetened nut or seed butter for these oats. I also prefer to use a smooth nut butter, but if you like a chunky texture then you could use a chunky nut butter instead.
- Protein powder: This is what makes these oats high in protein. I would recommend using vanilla protein powder for the best taste. You can use any type or brand of protein powder that you prefer.
- Ground flax seeds: flax seeds are a nice addition to these overnight oats because they're filled with omega-3 fatty acids and fiber. They also add a nice texture to this recipe. Instead of flax seeds you could use chia seeds instead.
- Sweetener: honey or maple syrup are great options to naturally sweeten this oatmeal and keep it refined sugar free. If you're following a vegan diet, use maple syrup.
- Additional toppings: I recommend bananas, berries or chocolate chips, whichever you prefer!

Top tips:
- The longer you let these oats set in the fridge, the more liquid they will absorb. Depending on how long you refrigerate them you may need to add a bit more milk before serving to give them the consistency you like.
- You can eat these overnight oats cold or heat them before serving.
- Use rolled oats rather than instant oats for this recipe.
Variations and add ins:
- To make these into vegan overnight protein oats: use a dairy-free milk such as coconut milk or almond milk, vegan protein powder, and maple syrup.
- To make these overnight oats gluten-free: be sure to use certified gluten-free oats and gluten-free protein powder.
- Dairy free variation: use a dairy-free milk and a dairy-free protein powder.
- To make these oats a little sweeter, add an extra tablespoon of honey or maple syrup or some jam such as my blueberry chia jam recipe or plum chia jam.
- Feel free to double or triple this recipe if you are meal prepping or serving more than one person.
How to store:
Store these oats for up to a week in the fridge in a sealed jar or airtight container.
You can freeze overnights oats in a small container and thaw them in the fridge the day before eating.
