Peanut Butter Banana Overnight Oats – A Creamy, Satisfying Make-Ahead Breakfast

If you want a breakfast that tastes like a treat but keeps you full for hours, this is it. Peanut butter banana overnight oats are creamy, naturally sweet, and super simple to make the night before. You get a little nutty richness, a touch of vanilla, and that classic banana flavor.

It’s the kind of meal that makes mornings feel easier. No stove, no fuss—just grab your jar and go.

Why This Recipe Works

This recipe balances flavor and texture in a way that feels both comforting and nourishing. The peanut butter adds richness and healthy fats that keep you satisfied, while the banana brings natural sweetness and creaminess.

Rolled oats soak overnight, turning silky without getting mushy. A splash of milk, a bit of yogurt, and a hint of vanilla make it taste like pudding—but with real staying power. It’s also endlessly adaptable, so you can tweak it to your taste without losing the core magic.

Ingredients

• 1/2 cup rolled oats (old-fashioned, not instant)
• 1/2 cup milk (dairy or unsweetened non-dairy)
• 1/4 cup plain Greek yogurt (or dairy-free yogurt)
• 1 medium ripe banana, mashed (plus a few slices for topping)
• 1–1.5 tablespoons creamy peanut butter
• 1–2 teaspoons honey or maple syrup (optional, to taste)
• 1/2 teaspoon vanilla extract
• Pinch of salt
• Optional add-ins: 1 tablespoon chia seeds or ground flaxseed, a sprinkle of cinnamon, mini chocolate chips, chopped peanuts, or a drizzle of extra peanut butter

Instructions

1. Mash the banana: In a bowl or jar, mash the banana until mostly smooth with a few small chunks for texture.
2. Stir in the wet ingredients: Add milk, Greek yogurt, peanut butter, vanilla, and sweetener if using.

   Whisk or stir until the peanut butter is fully incorporated.

3. Add the dry ingredients: Stir in rolled oats, a pinch of salt, and any optional chia or flax. Mix well so every oat gets coated.
4. Taste and adjust: If you like it sweeter, add a touch more honey or maple. If it seems too thick, splash in more milk.
5. Refrigerate overnight: Cover and chill for at least 4 hours, ideally 8–12 hours, to let the oats soften and thicken.
6. Serve: In the morning, give it a strong stir.

   Add banana slices, a drizzle of peanut butter, a few chocolate chips, or chopped peanuts on top.

7. Customize the texture: If it’s too thick, loosen with a little milk. If it’s too thin, stir in a spoonful of oats or chia and let it sit a few minutes.

Keeping It Fresh

Overnight oats keep well for up to 4 days in the fridge, but the banana flavor is brightest within the first 2–3 days. Store portions in airtight jars to prevent odors from the fridge seeping in.

If you want to prep several days ahead, consider adding fresh banana slices the morning of rather than storing them overnight. This helps maintain a clean flavor and better texture. For the creamiest results, give the oats a quick stir before serving to re-incorporate any separation.

Why This is Good for You

This bowl earns its keep nutritionally.

Oats provide soluble fiber (beta-glucan), which supports heart health and steady energy. Peanut butter contributes healthy fats and plant-based protein that help keep you full. The banana adds potassium and natural sweetness, reducing the need for added sugar.

Greek yogurt brings extra protein and probiotics, supporting gut health. The overall combo keeps your blood sugar steadier than many grab-and-go breakfasts.

Pitfalls to Watch Out For

• Using instant oats: They can turn mushy. Stick with rolled oats for the best texture.
• Too much sweetener: Banana already sweetens the mix.

  Add honey or maple sparingly, then adjust after chilling if needed.

• Dry oats on top: If you don’t stir well, some oats stay dry and chewy. Mix thoroughly so everything is coated.
• Overly thick texture: Chia and peanut butter can thicken a lot overnight. Start with a bit more milk if you’re adding chia, or loosen with milk in the morning.
• Metallic taste from containers: Use glass jars or BPA-free containers with tight lids for the cleanest flavor.

Alternatives

• Nut-free: Use sunflower seed butter or tahini.

  Both add richness; sunflower seed butter tastes closest to peanut butter.

• Dairy-free: Swap Greek yogurt for a coconut or almond yogurt and use your favorite non-dairy milk.
• High-protein: Stir in a scoop of vanilla or unflavored protein powder and an extra splash of milk to balance thickness.
• Lower sugar: Skip added sweeteners and rely on ripe banana. A pinch of cinnamon makes it taste sweeter without sugar.
• Crunch factor: Add toasted peanuts or cacao nibs right before serving to protect the crunch.
• Chocolate twist: Add 1 tablespoon cocoa powder and a few dark chocolate chips for a dessert-like feel.
• Berry boost: Fold in blueberries or sliced strawberries in the morning. Their tartness balances the creamy peanut butter.

FAQ

Can I use steel-cut oats?

Not for this exact method.

Steel-cut oats don’t soften enough overnight without cooking. If you want to use them, par-cook first or try a “quick” steel-cut variety and extend the soak time to 12–18 hours with extra milk.

Do I have to use Greek yogurt?

No. It adds creaminess and protein, but you can use regular yogurt or skip it and add an extra 2–3 tablespoons of milk.

If skipping yogurt, consider a spoonful of chia for thickness.

How ripe should the banana be?

Choose a banana with brown speckles. The riper it is, the sweeter and more pronounced the flavor will be. Very green bananas can make the oats taste flat and starchy.

Can I warm up overnight oats?

Yes.

Heat gently on the stovetop or in the microwave with a splash of milk, stirring often until warm. Add toppings after heating to keep textures balanced.

What’s the best peanut butter to use?

Natural, creamy peanut butter works well for clean flavor and smooth texture. If your peanut butter is very thick, warm it briefly or whisk it with a little milk before mixing.

How do I prevent separation?

Give the mixture a thorough stir before chilling and again before serving.

Chia seeds or a small amount of yogurt help bind the liquid and keep everything cohesive.

Is this suitable for meal prep?

Absolutely. Make 2–4 jars at once. Store the base without banana slices, then add fresh banana on the day you eat it for the best taste and texture.

Can I make it without sweetener?

Yes.

Use a ripe banana and a pinch of cinnamon or vanilla to amplify sweetness naturally. Taste after chilling—flavors meld and often seem sweeter the next day.
