5-Minute Banana Cream Pie Overnight Oats

These overnight oats taste like spooning into a slice of banana cream pie, but take about five minutes to stir together and zero minutes of cooking. Layers of mashed banana, creamy oats, and crushed graham crackers turn Tuesday morning into something you actually look forward to.

If you keep ripe bananas on the counter and a jar of rolled oats in the pantry, you are already halfway there. Everything sets up in the fridge while you sleep, waking up thick, cold, and legitimately close to the dessert it borrows its name from.

Why This Breakfast Works

The banana here pulls double duty. Half gets mashed into the oats to sweeten every bite without any added sugar, and the other half gets sliced into the jar so you hit soft, distinct fruit layers. That built-in sweetness means the whole thing tastes richer than it has any right to for a five minute breakfast.

The graham cracker layer on top does not just sit there looking cute. It softens just enough overnight to mimic the crust of a banana cream pie, staying distinct from the oats below. Eating it cold keeps the pudding vibe intact and, honestly, I like it better straight from the fridge than I ever did reheated oatmeal.

Ingredients

• 1 ripe banana, divided: half mashed, half sliced. The riper the banana, the sweeter the oats.
• 1/2 cup rolled oats: use old-fashioned rolled oats here. Quick oats turn mushy.
• 1/2 cup whole milk: or any milk you prefer. Whole milk gives the richest texture.
• 1/4 cup plain Greek yogurt: full-fat yogurt adds the tang and body that reads like pudding.
• 1 tbsp chia seeds: these thicken the mix and add a subtle crunch.
• 1/2 tsp vanilla extract: rounds out the banana flavor, no fake taste.
• Pinch of salt: just enough to wake everything up.
• 2 tbsp crushed graham crackers: for that pie-crust finish on top.
• Optional: 1 tsp maple syrup: only if your banana is not very ripe.

Variations

• Dairy-free: Swap the milk for oat milk and the yogurt for a coconut-based plain yogurt. Texture will be a touch thinner but still creamy.
• No chia seeds: Use 1 teaspoon of ground flaxseed instead, or leave seeds out entirely and expect a slightly looser set.
• Extra protein: Stir a tablespoon of vanilla or unflavored protein powder into the wet ingredients before mixing.
• Crunch swap: Swap graham crackers for crushed vanilla wafers or even a crumbled shortbread cookie.
• Peanut butter twist: Swirl a teaspoon of peanut butter into the oats before layering. It sounds odd but works like a banana cream pie with nutty depth.

Coffee Cinnamon Rolls make a lovely treat to go with these overnight oats.

How to Make Banana Cream Pie Overnight Oats

Step 1: Mash Half the Banana

Peel the banana and cut it in half. In a small bowl or right in the jar you plan to store the oats in, mash one half with a fork until it is a wet paste, about 30 seconds. Add the 1/2 cup rolled oats, 1/2 cup milk, 1/4 cup Greek yogurt, 1 tbsp chia seeds, 1/2 tsp vanilla, the pinch of salt, and the 1 tsp maple syrup if using. Stir everything until no dry oat clumps stick to the bottom, about 20 seconds of mixing. The mixture will look loose and thin at this stage, which is exactly right. It sets up as the chia and oats absorb liquid overnight.

Step 2: Layer the Oats and Banana

Slice the remaining banana half into thin rounds, about 1/4-inch thick. Spoon half of the oat mixture into a jar or bowl, then lay half the banana slices on top in a single layer. Cover them with the rest of the oats, then the rest of the banana slices. Give the jar a gentle tap on the counter so the layers settle but stay distinct. The banana slices in the middle soften just enough to taste like pie filling without dissolving.

Step 3: Add the Crumb Topping and Chill

Sprinkle the 2 tbsp crushed graham crackers evenly over the top. Seal the jar with a lid or cover the bowl tightly, then refrigerate for at least 4 hours, or overnight. The graham crackers will absorb a little moisture from the yogurt and banana, softening to a texture somewhere between a soft crust and a crumble. Pull it out when you are ready to eat and give the top a final look. Spoon straight in, cold, no stirring necessary, so you keep each layer visible.

A Few Notes Before You Start

• Use a jar with a wide mouth if you have one. It makes layering the banana slices easier and looks prettier when you open it in the morning.
• If your banana is green tipped, wait another day. The sweetness here depends almost entirely on how ripe that banana is, and a starchy one will leave the oats bland.
• Do not stir after adding the graham crackers. Their job is to sit on top and mimic crust, not dissolve into the entire jar.
• Make two jars at once and stash them in the fridge for a grab and go breakfast the next two days. The banana slices stay fresh and the grahams hold their texture.

Storing and Serving

• Refrigerate: Keep the jar sealed in the fridge for up to 3 days. The banana slices may darken slightly but they taste fine. The graham topping softens further after day one.
• Serve cold: This recipe is meant to be eaten straight from the fridge, no heating. Cold oats are what sells the pie illusion. Room temperature works if you forget to pull it out early.

Frequently Asked Questions

Can I use steel-cut oats?

No, steel-cut oats do not soften enough with just an overnight soak. Stick with rolled oats.

The oats came out too thick. What happened?

It is usually a chia seeds issue. If you packed the tablespoon too tightly, the extra chia absorbs more liquid. Stir in a splash of milk before eating to loosen it up.

Can I make this without yogurt?

Yes, though the texture shifts. Use an equal amount of milk plus an extra teaspoon of chia seeds to help it set. It will taste less tangy and a bit thinner.

Will the banana slices turn brown?

They darken slightly after 24 hours but do not spoil. The yogurt and milk create a barrier that slows oxidation compared to banana slices left in open air.
