The bowl looks almost too loose when you first stir it together, but that’s exactly how it should be. After a night in the fridge, the oats soften and the mixture turns thick and creamy, with banana folded right into every spoonful. These banana cream pie overnight oats get their pie-like finish from vanilla pudding mix, then graham cracker crumbs add a little crunch on top.
I like that the jars are ready to grab straight from the refrigerator, with no morning cooking or extra bowls to wash. The mashed banana sweetens the oat mixture, while the sliced half gives each serving a fresh banana layer. Add the whipped topping and crumbs just before serving, and you’ve got a chilled breakfast that tastes like a familiar dessert without asking you to bake a crust.

Kitchen Note
Mash the banana half until you don’t see big chunks before stirring it into the oats. That gives the mixture a smooth banana flavor instead of pockets of fruit.
Save these banana cream pie overnight oats for a make-ahead breakfast with creamy vanilla oats and a graham-cracker finish.
Why These Oats Set Like Pie Filling Instead of Turning Gummy
Overnight oats need enough time to absorb their liquid, but a thick, spoonable texture depends on more than waiting. Here, old-fashioned rolled oats soften gradually, chia seeds help the mixture hold together, and instant vanilla pudding mix gives it that smooth, pie-filling character. The Greek yogurt adds body, too, so the finished jars feel creamy rather than like plain oats floating in milk.
That combination is also why quick oats aren’t the best stand-in. They soften faster and can lose their distinct, tender bite during a long chill. With rolled oats, the mixture may look loose right after stirring, then settle into a thicker texture as it rests. Resist the urge to judge it from the bowl; the overnight chill is part of the method, not just storage.
The banana plays two roles without making the base taste like fruit purée. The mashed portion blends into the oats, while the sliced portion stays visible at the top. That contrast keeps the jars recognizable as banana cream pie oats instead of one uniform, overly soft mixture.
What Gives the Oats Their Creamy Banana-Pie Character

- Old-fashioned rolled oats — These hold their shape while they soften in the refrigerator, which gives the jars a tender, chewy texture. Quick oats become softer during the same long chill, so rolled oats are the better choice for this texture.
- Milk and plain Greek yogurt — Milk gives the oats enough moisture to soften, while Greek yogurt makes the base creamy and substantial. Plain yogurt matters here; a sweetened or flavored one changes the sweetness and can make the vanilla taste less clear. A different kind of dairy milk works in the same role, though the finished oats may feel a little less rich.
- Instant vanilla pudding mix — This brings the recognizable vanilla cream-pie note and helps the mixture thicken. It’s doing more than adding vanilla flavor, so vanilla extract alone won’t replace it or create the same texture.
- Chia seeds — As the jars chill, the seeds absorb moisture and help the mixture set. They’re a small ingredient with a noticeable effect; leaving them out gives you a looser base.
- Vanilla extract — A little rounds out the vanilla taste from the pudding mix. Use the extract you already keep for baking; there’s no need for a specialty bottle here.
- Ripe banana — A ripe banana is soft enough to mash into the oats and sweet enough to carry its flavor through the chilled base. If it’s still firm and pale, it’s harder to mash smoothly and tastes less sweet.
- Whipped topping and graham cracker crumbs — The thawed topping gives the jars their light, pie-style finish, and the crumbs bring the familiar crust note. The crumbs are best added at serving so they stay distinct instead of softening against the oats.
Mixing and Chilling the Oats for a Spoonable Texture
Stir the vanilla-banana base
In a medium bowl, stir together the rolled oats, milk, plain Greek yogurt, instant vanilla pudding mix, chia seeds, vanilla extract, and mashed half of the banana. Keep stirring until the pudding mix is evenly distributed and you don’t see dry patches or clumps. The mixture will look soft and loose at this point, which is normal before the oats and chia have had time to absorb moisture. If dry pudding mix remains in a pocket, keep stirring so it doesn’t stay concentrated in one jar.
Divide it between the jars and let it rest
Divide the mixture between two 12-ounce jars, then cover them and refrigerate for at least 6 hours or overnight. Use a spoon to distribute the mixture evenly rather than filling one jar first and guessing at the second. After chilling, the oats should look thicker and feel soft when you stir through them. A short rest won’t give the rolled oats enough time to reach that texture, so plan for the full chill.
Add the pie-style finish
Top each jar with half of the thawed whipped topping, the sliced banana, and graham cracker crumbs. The topping goes on after chilling, so it stays separate from the oat base. Arrange the banana slices over the surface, then finish with the crumbs for a little contrast in texture. Serve the jars once they’re topped rather than chilling them again for a long stretch with the crumbs already in place.
Two Small Changes for a Different Kind of Jar
A Lighter, Less-Sweet Finish
Leave off the whipped topping and finish the chilled oats with the sliced banana and graham cracker crumbs. You’ll lose the cloudlike pie topping, but the vanilla-banana base and crunchy crumbs still carry the dessert-inspired idea with a less rich finish.
Make the Banana a Middle Layer
For a layered look, divide the oat mixture between the jars, add the sliced banana across the middle, then finish with the remaining oats before chilling. The banana softens into the center during its rest, so the jars look more like a layered pudding and less like oats with fruit on top.
Storage and Reheating
- Refrigerator: Keep the jars covered and refrigerated, and enjoy them within 2 days for the best texture. The banana softens and darkens as it sits.
- Freezer: Freezing isn’t a good fit; the yogurt and banana can turn watery and soft after thawing.
- Reheating: These are meant to be eaten chilled, so no reheating is needed. Warming them melts the whipped topping and changes the texture of the oats.
