Banana Biscoff Overnight Oats Recipe (Easy & Creamy)

This recipe works best for rolled oats soaked overnight (8–12 hours). It won’t give the same texture if you use instant oats or soak for less than 6 hours.

Biscoff spread on overnight oats sounds almost too good to be real. It isn’t. This combination, ripe banana, caramelized cookie butter, and thick creamy oats, comes together in one jar, in five minutes, the night before you need it.

No cooking. No morning stress.

Here’s what most recipes get wrong: they tell you to mix the Biscoff spread directly into the oats before soaking. That kills the flavor. The spread loses its distinct caramelized edge and just becomes a vague sweetness you can’t quite identify. The fix is simple, and this guide covers it.

What Are Banana Biscoff Overnight Oats?

Banana Biscoff overnight oats is a no-cook breakfast made by soaking rolled oats in milk or yogurt overnight, then topping with mashed or sliced banana and Lotus Biscoff cookie butter spread. The oats absorb the liquid while you sleep, creating a thick, pudding-like texture that needs zero morning effort.

According to the British Nutrition Foundation (2023), oats are one of the highest-fiber breakfast grains available, with beta-glucan content shown to support sustained energy release, making this more than just a pretty jar.

Biscoff spread, made by Lotus Bakeries, is a Belgian cookie butter with a distinct caramelized spice flavor. It pairs with banana the same way peanut butter does, except warmer, more complex, and significantly harder to stop eating.

Ingredients You Need

The ratios below make one jar. Scale up directly for meal prep.

½ cup (45g) rolled oats — not instant, not steel-cut
½ cup (120ml) milk of choice (whole milk gives creamiest result; oat milk works well too)
¼ cup (60g) plain Greek yogurt
1 tablespoon chia seeds (optional but recommended for thickness)
1 teaspoon honey or maple syrup
½ ripe banana — mashed into the base, other half sliced for topping
1–2 tablespoons Lotus Biscoff spread — for topping only
1–2 Biscoff biscuits, crumbled — for crunch (optional)

Quick note: The banana must be ripe. Green or firm bananas don’t mash properly and their flavor doesn’t come through. You want brown spots on the skin, that’s where the natural sweetness lives.

How to Make Banana Biscoff Overnight Oats

To make banana Biscoff overnight oats, follow these steps:

Mash half the banana in the bottom of your jar or container
Add oats, milk, yogurt, chia seeds, and honey on top of the mashed banana
Stir everything together until fully combined
Seal the jar and refrigerate for at least 8 hours, up to 24 hours
In the morning, stir the oats and check consistency, add a splash of milk if too thick
Top with sliced banana, a drizzle of Biscoff spread, and crumbled biscuits
Serve cold, or microwave for 60–90 seconds if you prefer it warm

That’s it. Seven steps, five minutes of actual work.

Here’s the thing: step 6 is where most people make the mistake of mixing the Biscoff in rather than drizzling on top. Keep it on the surface. Every bite should hit the spread first, that contrast between cold oats and the rich cookie butter layer is exactly the point.

Getting the Texture Right

Texture is the most common complaint with overnight oats. Too runny. Too thick. Gluey. Weirdly dense.

The fix is almost always the liquid ratio.

The base ratio that works: 1 part oats to 1 part liquid. If you add Greek yogurt (which you should), reduce the milk slightly, yogurt counts as liquid and adds body. The recipe above uses a 1:1 oat-to-total-liquid ratio including the yogurt, which produces a thick, spoonable consistency after 8 hours.

Chia seeds change everything once you add them. They absorb up to 10 times their weight in liquid, so if your oats feel too thin after soaking, chia seeds are the first adjustment to make, not adding more oats.

Or maybe I should put it this way: think of chia seeds as your texture insurance. Add them, and you almost can’t get the consistency wrong.

Too thick in the morning? Add 2–3 tablespoons of milk and stir. Too thin? You likely used too much liquid or didn’t soak long enough. Refrigerate for another 2 hours.

Biscoff Spread vs. Biscoff Biscuits — Do You Need Both?

Quick Comparison

Option	Best For	Key Benefit	Limitation
Biscoff Spread (smooth)	Drizzling on top	Creamy, rich, melts slightly into oats	High in sugar — use 1–2 tbsp max
Biscoff Spread (crunchy)	Mixing into base	Adds texture throughout	Harder to find in some regions
Biscoff Biscuits (crumbled)	Topping for crunch	Textural contrast, visual appeal	Softens quickly — add just before eating
Both spread + biscuits	Full Biscoff experience	Maximum flavor + crunch	Richest version — not for light eaters

Biscoff spread is better suited for the topping layer because it drizzles cleanly and delivers that caramelized hit right on the first spoonful. Biscoff biscuits work better when you want textural contrast, crumble them on just before eating so they don’t turn soggy overnight.

You don’t need both. The spread alone makes a complete recipe. Biscuits are the upgrade.

Meal Prep: Making 5 Jars at Once

Overnight oats are one of the best meal prep breakfasts available. Full stop.

Make five jars on Sunday night and you’ve handled breakfast through Friday without thinking about it again. The base, oats, milk, yogurt, chia, mashed banana, keeps well in the fridge for up to 4 days. Don’t add the Biscoff topping or sliced banana until the morning you eat it. Sliced banana oxidizes and turns brown; Biscoff on top loses its visual appeal by day two.

Storage tip: Use wide-mouth mason jars (480ml / 16oz) for easy stirring and eating directly from the jar. Clip-top glass containers work too. Avoid plastic if possible, oats can absorb faint plastic odors over 3–4 days.

I’ve seen conflicting advice on whether to add chia seeds at prep time or the night before eating, some sources say pre-adding makes oats too thick by day 4. My read is that it depends on your milk. Full-fat dairy with chia seeds does get very thick by day 3–4. If you’re prepping 5 days ahead with whole milk, add chia seeds fresh each night rather than at batch prep time.

Variations Worth Trying

Once you’ve nailed the base recipe, these variations are worth making:

High-protein version: Replace Greek yogurt with skyr (Icelandic-style strained yogurt with higher protein content) and add one scoop of vanilla protein powder. Increase milk by 2 tablespoons to compensate for thickness. Macros shift from roughly 15g to 28–32g protein per jar depending on your powder.

Vegan version: Use oat milk or coconut milk instead of dairy, swap Greek yogurt for a coconut-based yogurt, and replace honey with maple syrup. Biscoff spread is already vegan, Lotus Bakeries confirmed this on their official product page.

Chocolate Biscoff version: Add 1 tablespoon of cocoa powder to the base mixture. The bitterness of cocoa cuts through the sweetness of Biscoff and creates something that genuinely tastes like dessert for breakfast.

Warm version: Microwave the fully soaked oats (without the banana topping) for 90 seconds, stir, then add toppings. The Biscoff spread melts slightly over warm oats. This is the version for cold mornings.

Nutrition at a Glance

This is not a low-calorie recipe, and it’s not trying to be. One jar using the base recipe with whole milk, Greek yogurt, and 1 tablespoon of Biscoff spread comes to approximately:

Calories: 420–460 kcal
Protein: 14–16g
Carbohydrates: 58–62g
Fat: 12–15g
Fiber: 7–9g (notably high, largely from oats and chia)

Switch to skyr and low-fat milk to bring calories down to roughly 350 kcal with protein closer to 22g. These are estimates, exact values depend on brands used.

Voice Search Q&A

Can I use instant oats instead of rolled oats for overnight oats?

You can, but the texture turns mushy. Instant oats over-absorb liquid and lose structure. Rolled oats hold their shape after soaking and give a far better texture.

How long should I soak overnight oats?

At least 8 hours for the best texture. 6 hours is the minimum. Beyond 24 hours the oats start to get too soft, especially if you’ve used chia seeds.

Can I make Biscoff overnight oats without yogurt?

Yes, just increase milk to ¾ cup instead of ½ cup. The oats will be slightly less thick and creamy, but the recipe works fine without yogurt.

Why does my banana turn brown in overnight oats?

Sliced banana oxidizes when exposed to air. Add banana slices as a topping in the morning, not the night before. Mashed banana mixed into the base is fine, it won’t discolor noticeably.

Should I eat Biscoff overnight oats cold or warm?

Cold is the standard. The thick, pudding-like texture is best straight from the fridge. Warm works well in winter, microwave 60–90 seconds without the toppings, then add them after.
