If you're looking for a breakfast that tastes exactly like dessert but keeps your macros on point, this is it. These banana overnight oats pack over 35g of protein and take less than five minutes of actual work to prep for the week.
The secret here is the banana cream pudding mix. It transforms standard oats into a thick, custard-like base that mimics the filling of a traditional pie. We're skipping the heavy cream and butter but keeping all the flavor.

The Custard Strategy
To get that signature “pie” texture, we rely on modified cornstarch found in the sugar-free pudding mix. When whisked with milk and oats, it creates a thick, velvety bind that prevents the oats from becoming soupy. By letting this sit overnight in an airtight container, the oats hydrate fully while the pudding mix sets the liquid into a cream. Adding a touch of chia seeds also helps lock in that structure if you prefer an even thicker consistency.
Why You'll Love This Recipe
- Macro-Friendly Dessert: You get the nostalgic flavor of banana cream pie with a massive protein boost and minimal fat.
- Zero-Cook Prep: This is a “set it and forget it” meal. Perfect for busy mornings when you don't have time to turn on the stove.
- Stay Full Longer: The combination of fiber from the oats and high-quality protein ensures you won't be reaching for snacks an hour later.
- Perfect Texture: Unlike watery instant oats, the pudding mix provides a thick, structured mouthfeel that feels indulgent.
- Customizable: It's easy to fold in extra ingredients like walnuts or chocolate chips without ruining the macro balance.
Key Equipment Focus
To get the most out of this recipe, I highly recommend using a Digital Scale. Measuring by volume (cups) is notoriously inaccurate with oats and protein powder; weighing in grams ensures your oats aren't too dry or too runny every single time. I mix everything in a standard glass mason jar, but having a solid Silicone Spatula Set is key to scraping down the sides so you don't waste any of that high-protein goodness. If you don't have a jar, any standard mixing bowl works, provided you cover it tightly.
Ingredient Deep Dive & Strategy
- Rolled Oats: Use Old Fashioned rolled oats. Quick oats will turn to mush, and steel-cut won't soften enough overnight.
- PE Science Vanilla Protein: I use PE Science (Code: BAKEDLEAN) because it's a Whey/Casein blend. 100% whey often results in a thin, watery consistency. The casein in this blend is essential for that thick, creamy pie structure.
- Unsweetened Vanilla Almond Milk: This provides a neutral, low-calorie liquid base that lets the banana flavor shine.
- Banana Cream Pudding Mix: Make sure it's the “Instant” kind. This provides the flavor and the thickening power without needing heat.
- Vanilla Extract & Cinnamon: A dash of each balances the sweetness and brings out the classic “baked goods” aroma.
- Chia Seeds: Optional, but great for adding extra fiber and helping the mixture set.
- Ripe Bananas: Super ripe bananas ensure super smooth and creamy oats!
Banana Cream Pie Overnight Oats Ingredients
Base Ingredients
- 80g Rolled Oats (approx. 1 cup)
- 33g PE Science Vanilla Protein Powder (1 scoop)
- 240ml Unsweetened Vanilla Almond Milk
- 16g Sugar-Free Banana Cream Instant Pudding Mix
- 5g Chia Seeds
- 1/2 tsp Vanilla Extract
- 1/4 tsp Cinnamon
- 30g Sugar-free maple syrup
- 1g Salt (a pinch)
Toppings
- 1/2 Banana, sliced
- 1 Graham cracker sheet, crushed
Banana Cream Pie Overnight Oats Step by Step Instructions
1. Combine dry ingredients: In a glass mason jar or container, add your oats, protein powder, instant pudding mix, chia seeds, cinnamon, and salt. Stir these together first to ensure the pudding mix and protein are evenly distributed.
Using a dry whisk or fork here prevents “protein clumps” from forming once the liquid hits the jar.
2. Add wet ingredients: Pour in the unsweetened vanilla almond milk, vanilla extract, and the sugar-free maple syrup. Stir vigorously until no dry pockets of protein remain at the bottom of the jar.
Make sure to scrape the bottom edges of the jar with your spatula; protein powder loves to hide there and stay dry.
3. The overnight set: Seal the container and place it in the fridge for at least 4 hours, though overnight (8 hours) is best for the thickest texture.
If the oats look too thick in the morning, splash in one extra tablespoon of milk to loosen them up before eating.
4. Top and serve: Just before eating, slice a fresh banana on top and crumble your graham cracker.
Do not add the graham crackers the night before, or they will lose their crunch and become soggy.
Troubleshooting & FAQ
Why are my oats liquidy? You likely used a 100% whey protein. Casein is what provides the “fluff” and thickness. Next time, use slightly less milk or switch to a blend. If you are stuck with whey, add a teaspoon of chia seeds to help absorb the extra moisture.
Can I make this taste like banana bread overnight oats? Absolutely. Swap the banana cream pudding mix for vanilla pudding mix, increase the cinnamon to 1/2 teaspoon, and stir in a tablespoon of chopped walnuts.
Is the salt necessary? Yes. Salt balances the sweetness of the pudding mix and makes the banana flavor pop. Without it, the oats can taste flat.
Can I add chocolate chips? Definitely. Fold in 10g of dark chocolate chips right before serving. They pair perfectly with the banana profile.
What is the best way to store these? Use an airtight container or a mason jar. This keeps the oats fresh for up to 4 days in the fridge. Avoid using an open bowl unless you cover it tightly with plastic wrap.
Can I make this vegan? Yes, use a vegan protein powder and plant-based milk. Note that vegan proteins absorb much more liquid than whey/casein, so you may need an extra 1/4 cup of milk.
Substitutions Table
| Component | Swap Options |
| Pudding Mix | Vanilla Pudding Mix + Banana Extract |
| Sweetener | Honey, Agave, or Stevia drops |
| Graham Crackers | Vanilla wafers or crushed Biscoff cookies |
| Protein Powder | Greek Yogurt (use 1/2 cup and reduce milk to 1/2 cup) |
Storage & Reheating
Fridge: These stay fresh for up to 4 days in a sealed container.
Freezer: Not recommended. The texture of the oats and pudding mix changes significantly upon thawing.
Heat: While these are designed to be eaten cold, you can microwave them for 60 seconds if you prefer warm oats.
