I love how easy these oats are to make. Just mix everything in a jar and let it sit overnight. In the morning, breakfast is ready, and it tastes like a warm apple pie! 🍏✨
Key Ingredients & Substitutions
Old-Fashioned Rolled Oats: These oats give the best texture for overnight oats. If you want a quicker option, instant oats work too, but they’ll be softer. For a gluten-free version, make sure to choose certified gluten-free oats.
Milk: Any milk works here! I love almond milk for a subtle nutty flavor, but coconut milk adds a creaminess. You can also use oat milk or regular cow’s milk depending on your preference.
Protein Powder: Vanilla flavor is great for this recipe, but if you prefer chocolate or another flavor, go for it! If you’re avoiding protein powders, you could substitute with Greek yogurt for added protein.
Chia Seeds: These add a nice texture and some healthy fats. If you don’t have them, you can skip them or use flaxseeds. Just be aware that the liquid absorption will change a bit.
Apple: I recommend using a crisp apple like Granny Smith or Honeycrisp for a nice bite. If you’re short on apples, pears work well too, or even dried fruits like raisins or cranberries for a different flavor.
How Can You Achieve the Perfect Overnight Oats Consistency?
The key to great overnight oats is the right liquid-to-oat ratio. Here’s how to get it just right:
- Start with 1/2 cup of oats and 1/2 cup of liquid, which is usually perfect for most preferences.
- If you like thicker oats, you can reduce the liquid. For creamier oats, add more milk.
- Let them soak for at least 6 hours, or overnight, to let the oats absorb the liquid fully.
In the morning, check if it’s too thick; if so, mix in a bit more milk until you reach your desired consistency.

Apple Cinnamon Protein Overnight Oats
Ingredients You’ll Need:
Base Ingredients:
- 1/2 cup old-fashioned rolled oats
- 1/2 cup milk (dairy or plant-based)
- 1/2 scoop vanilla or unflavored protein powder
- 1/2 teaspoon ground cinnamon
- 1 small apple, diced (about 1/2 cup)
- 1 tablespoon chia seeds (optional, for added texture and nutrition)
- 1 teaspoon maple syrup or honey (optional, for sweetness)
- 1/4 teaspoon vanilla extract (optional)
- A pinch of salt
For Garnish:
- Additional apple slices
- Sprinkle of ground cinnamon
Time Needed:
This recipe only takes about 10 minutes to prepare. You will need to let it chill in the fridge overnight or for at least 6 hours. So, in total, set aside about 6 hours and 10 minutes for preparation and chilling.
Step-by-Step Instructions:
1. Combine the Dry Ingredients:
In a mason jar or a bowl, mix together the rolled oats, protein powder, ground cinnamon, chia seeds (if using), and a pinch of salt. Stir these dry ingredients until they are well combined.
2. Add the Liquids:
Pour in the milk, along with the vanilla extract and maple syrup or honey, if you’re using them. Stir everything together until well combined, ensuring the protein powder is fully dissolved.
3. Mix in the Apples:
Gently fold in the diced apple pieces into your oat mixture. The apples will add flavor and a nice crunch!
4. Prepare for Chilling:
Seal the jar tightly or cover the bowl with a lid or plastic wrap. Place it in the refrigerator and let it chill overnight or for at least 6 hours. This allows the oats to absorb the liquid and soften.
5. Check and Adjust Consistency:
When you’re ready to eat, give the oats a good stir. If they seem too thick for your liking, add a splash of milk to reach your preferred consistency and mix well.
6. Garnish and Serve:
Top your oats with additional fresh apple slices and a sprinkle of cinnamon for an extra delicious touch.
7. Enjoy:
Your apple cinnamon protein overnight oats are now ready! You can enjoy them cold straight from the fridge, or if you prefer, warm them briefly in the microwave.
Can I Use Quick Oats Instead of Rolled Oats?
Yes, you can use quick oats, but keep in mind they will absorb liquid faster and result in a creamier texture. If you like a bit more chewiness, stick with rolled oats!
How Can I Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. Just give it a good stir before eating, and you can add a splash of milk to freshen it up if it thickens.
Can I Make These Oats Vegan?
Absolutely! To make this recipe vegan, use plant-based milk (like almond or oat milk) and replace honey with maple syrup or agave nectar.
What Other Fruits Can I Add?
Feel free to mix in other fruits such as berries, bananas, or pears. Just remember to adjust the sweetness according to the fruit’s natural sugar content!
