Reasons You’ll Love This Recipe:
- High-Protein – With 39 grams of protein per serving, this breakfast keeps you full and fueled all morning.
- High-Fiber – 11 grams of fiber means steady energy and no mid-morning crash.
- Make-Ahead – Mix it up the night before and grab it straight from the fridge on your way out the door.
- Cozy Flavor – Warm cinnamon and sweet diced apple taste like dessert for breakfast.
- Easy to Customize – Swap the protein powder or nut butter for whatever you already have on hand.
Ingredients & Substitutions
- Milk – Any milk works here; dairy, almond, or oat milk are all great options.
- Vanilla Greek Yogurt – Adds creaminess and extra protein; plain Greek yogurt works too if you stir in a touch more maple syrup.
- Almond Butter – Any nut or seed butter works, like peanut butter or sunflower seed butter for a nut-free option.
- Old-Fashioned Oats – Rolled oats give the best texture; steel-cut oats won’t soften properly overnight, so stick with old-fashioned or quick oats.
- Ground Flax Seeds – Boosts fiber and omega-3s; can be left out if you don’t have any on hand.
- Chia Seeds – Helps the oats thicken into that classic pudding-like texture.
- Cinnamon – The star flavor here; feel free to add a pinch of nutmeg or apple pie spice too.
- Vanilla Protein Powder – Any whey or plant-based vanilla protein powder works; unflavored protein powder is fine if you add a splash of vanilla extract.
- Maple Syrup – Optional for extra sweetness; honey works as a swap.
- Diced Apple – Any apple variety works, but a sweeter one like Honeycrisp or Gala pairs best with the cinnamon.
How to Make Apple Cinnamon Overnight Oats
For complete instructions, please check out the recipe card at the bottom of this post.
- Combine everything. In a jar or container, whisk together the milk, vanilla Greek yogurt, almond butter, maple syrup (if using), oats, flax seeds, chia seeds, cinnamon, and protein powder until fully combined.
- Stir in half the apple. Fold in half of the diced apple.
- Top and refrigerate. Top with the remaining diced apple and a sprinkle of cinnamon, then cover and refrigerate overnight (or at least 4 hours).
- Enjoy. Eat cold straight from the fridge, or warm it up if you prefer.
Tips & Variations
- Adjust the Consistency – I prefer a thicker overnight oats, but if you prefer yours thinner (or if your protein powder makes them thicker) add another 1-2 tablespoons of milk before consuming.
- Make It Extra Creamy – Stir in an extra tablespoon of Greek yogurt if you like a thicker, richer texture.
- Add Crunch – Top with chopped pecans or walnuts for a little crunch and healthy fats.
- Swap the Fruit – Diced pear works beautifully in place of apple if that’s what you have on hand.
- Warm It Up – If you prefer warm oats, microwave for 60-90 seconds and stir before eating.
- Boost the Cinnamon Flavor – Add a pinch of apple pie spice or nutmeg alongside the cinnamon for extra warmth.
Meal Prep & Storage
Fridge – Store in an airtight container in the fridge for up to 3-4 days.
Freezer – Not recommended; the texture of yogurt-based overnight oats doesn’t hold up well after freezing.
Recipe FAQs
Overnight oats are gluten-free as long as you’re using certified gluten-free oats.
Either! Overnight oats are often eaten cold, but they can easily be warmed. To warm them up, heat in a microwave-safe container for 30 seconds at a time, stirring between each round. You can also reheat in a pot on the stove over medium heat, but you’ll likely need to add a splash more liquid since some cooks out during reheating.
Overnight oats can absolutely be part of a healthy, balanced diet. (Remember – it’s not really about individual foods, but more so about your overall eating pattern.) Overnight oats like these are typically a great source of fiber, plus protein from the yogurt, milk, and protein powder. Check my article here to learn more: Are Overnight Oats Healthy?
Overnight oats last about 3-4 days in the fridge. If you need them to last longer than that, prep the dry ingredients in a mason jar and store it in your pantry – then add the milk and yogurt the night before you need them.
A few things can affect how much liquid your oats absorb – the type of milk, yogurt, protein powder, and oats (old-fashioned vs. quick) all play a role. Personal preference matters too, since some people like theirs thicker and creamier while others prefer them thinner. Play around with your ratios to find what works best for you.
