These Apple Pie Overnight Protein Oats are a creamy, high-protein breakfast made with oats, apples, warm cinnamon, and protein powder for a cozy apple pie flavor. An easy, make-ahead meal prep breakfast perfect for busy mornings.

About This Recipe
Mornings can get crazy in our house. If you are like us, it’s super helpful to have a quick and easy breakfast ready to go. I love making baked oats ahead of time and breakfast sandwiches on the fly.
But my new favorite macro-friendly breakfast has got to be apple pie overnight protein oats. These oats make mornings so easy because everything is prepped ahead of time the night before. Plus, you start your day with something that is delicious and good for you!

Ingredients and Substitutions
- Old-fashioned oats: Use gluten-free if needed.
- Chia seeds: Any type of chia seeds (black, white, or a mix) works for this recipe. Chia seeds are a great source of omega-3s and protein.
- Cinnamon: Warm, cozy, and perfect for pairing with apples. The cinnamon adds just the right amount of spice to these overnight oats.
- Vanilla extract: For a little extra flavor!
- Protein powder: Grab your favorite protein powder. I used vanilla protein powder. My favorite brands are Clean Simple Eats, or for a dairy-free option, I love Active Stacks! Use code LILLIE for a discount.
- Milk: My favorite milk is the Silk cashew milk but use your favorite milk.
- Apple: I like using a sweeter variety like Honeycrisp, Fuji, or Gala, but tart apples like Granny Smith work too if you prefer more contrast.
How to Make
- In a jar or small pyrex bowl, combine your oats, chia seeds, cinnamon, vanilla, and salt.
- Next, blend your protein powder with milk. My ALL-TIME favorite non-dairy protein is Active Stacks which is a beef protein powder. For this recipe, I used Active Stacks vanilla protein powder flavor, but their chocolate is my very favorite! Especially in my night time peanut butter chocolate shake. If you haven’t tried Active Stacks, use my code Lillie for 10% off your purchase. It is so yummy!
- Once you’ve blended your favorite protein powder with your milk of choice, pour it over the oats, and combine well. If your powder dissolves easily, simply throw both into the jar without blending!
- To finish off your overnight protein oats, stir in your diced apples. Then pop it in the fridge overnight and dream about the delicious breakfast you will get to enjoy come morning. I like mixing my oats once or twice during the process to make sure the chia seeds don’t get clumpy. You don’t have to mix it, but I think it makes the texture even better.
- Talking about texture, if you like your oats extra thick, use a little less milk when putting the recipe together. I like mine to last longer! Haha…So, I stir in extra milk before eating them.
- Enjoy the next morning!

I get a lot of questions about the jars I use for overnight oats and puddings. Here they are, my favorite jars for overnight oats. These jars are THE perfect size. Plus, I love that they are glass and you can see all the yummy goodness!
Serving Suggestions
I love to top my apple pie overnight protein oats with additional apples, cinnamon, and a little dairy-free whipped cream.

It’s the only overnight oats recipe I actually like!
Yum! Filling, super easy to make a bunch at the beginning of the week! Lillie never disappoints!
These are the best! I also love to use the CSE snickerdoodle instead of vanilla sometimes. Love the crunch of the apples.
This is so delicious! I’ve made it the last couple nights to have in the morning and I’ve looked forward to it each morning. Only problem is I wish it was as big as your Smoothie Bowl 😂
These are delicious and filling just like all Lillie recipes!
