5-Minute Biscoff Overnight Oats
Biscoff overnight oats turn your morning into a spoonable cookie dream, thick and luscious with that deep cinnamon-spice brown sugar warmth. They come together in five minutes flat the night before, so all you do is grab a jar.
No cooking, no rushing, just oats so creamy they taste like cookie butter in a bowl. The crushed cookies on top give you that crisp snap you’d miss otherwise, making every bite feel like a real treat.
Why This Biscoff Oats Recipe Works
The combination of milk and yogurt creates a velvety base that soaks into the oats just enough overnight without getting gluey. Stirring in the Biscoff spread while the mixture is still being combined lets its caramelized spice flavor melt through every layer instead of staying in a pocket.
I keep coming back to this version because the texture stays spoon-coating but never heavy. A pinch of salt pulls the sweetness forward so the cookie flavor pops cleanly, not cloying.
Ingredients
- 1/2 cup old-fashioned rolled oats: old-fashioned give you the best chewy texture; quick oats turn mushy
- 1/2 cup whole milk: any dairy or unsweetened plant milk works; oat milk makes it extra creamy
- 1/4 cup plain yogurt: Greek or regular, full-fat gives the richest finish
- 2 tbsp Biscoff cookie spread: smooth or crunchy both work; use smooth for a silky texture throughout
- 1/4 tsp vanilla extract: rounds out the warm spice notes
- Pinch of salt: just enough to wake up the sweetness
- 1 Biscoff cookie, crushed: for that crisp, buttery crunch on top
Variations / Substitutions
- Make it vegan: use a thick plant-based yogurt and milk. Biscoff spread and the cookies are already vegan, so the swap is seamless.
- Extra protein: stir in a tablespoon of vanilla protein powder with the dry oats, then add an extra splash of milk to keep the mixture pourable.
- More warming spice: add 1/4 teaspoon cinnamon or a whisper of nutmeg when you mix the base.
- Chocolate twist: melt a tablespoon of dark chocolate chips into the warm Biscoff layer before chilling, or mix in a teaspoon of cocoa powder.
- Crunch swap: crumble a handful of speculoos or gingersnaps instead of the Biscoff cookie for a different spiced snap.

How to Make 5-Minute Biscoff Overnight Oats
Step 1: Mix the Oat Base
In a jar or small bowl, combine the 1/2 cup oats, 1/2 cup milk, 1/4 cup yogurt, 2 tbsp Biscoff spread, 1/4 tsp vanilla, and a pinch of salt. Stir with a spoon for a full 30 seconds until everything is uniform and no streaks of cookie spread cling to the bottom; the mixture will look pale beige and slightly loose. That looseness disappears overnight as the oats absorb the liquid.
Step 2: Chill Overnight
Cover the jar and refrigerate for at least 8 hours, or overnight. As it sits, the oats soften and the Biscoff flavor deepens, turning the whole thing custard-thick. If you peek after 6 hours it will look set but the oats still carry a tiny raw chew, so let the full 8 hours pass for the smoothest texture.
Step 3: Top and Serve
Remove the jar from the fridge, give the oats a good stir to loosen them, then scatter the crushed Biscoff cookie over the top. If you like an extra drizzle, add another 1/2 teaspoon of warm cookie spread right before the cookies so they stick. Eat it cold straight from the jar, or let it sit on the counter for 10 minutes if you prefer a less chilled bite.
Tips for the Creamiest Biscoff Oats
- Stir the spread in completely at the start. A lump of unmixed Biscoff at the bottom of the jar will harden in the fridge and throw off the texture. Really dig the spoon down.
- Use whole milk and full-fat yogurt if you can. Low-fat versions will set up thinner and less rich, though they still work.
- Warm the Biscoff spread before stirring: if it’s cold from a cold pantry. Ten seconds in the microwave or a warm water bath makes it blend in smoothly without clumping.
- Don’t skip the salt. It’s the difference between a flat sweet note and that rounded cookie flavor you taste in a biscuit.
Scale it up for a few mornings:
| Servings | Rolled Oats | Milk | Yogurt | Biscoff Spread |
|---|---|---|---|---|
| 1 | 1/2 cup | 1/2 cup | 1/4 cup | 2 tbsp |
| 2 | 1 cup | 1 cup | 1/2 cup | 4 tbsp |
| 4 | 2 cups | 2 cups | 1 cup | 8 tbsp |
Storing Leftover Oats
Refrigerate: cover the jar tightly and keep in the fridge for up to 3 days. The oats will continue to thicken a little, so stir in a splash of milk when you’re ready to eat. Eat them cold or gently warm in the microwave for 30 seconds, just until they loosen. The crushed cookie topping is best added right before eating, otherwise it turns soft.
Frequently Asked Questions
Can I use quick oats instead of rolled oats?
You can, but the texture becomes much softer and almost porridge-like, losing that pleasant chew. If that’s what you have, reduce the milk by a tablespoon to keep the mixture from turning watery.
Is this recipe good for meal prep?
Yes, it holds well for three days in the fridge. Make up to four jars at once, but add the crushed cookies only to the jar you’re eating that morning.
Can I skip the yogurt?
The yogurt adds tang and a creaminess that milk alone won’t give. If you skip it, replace it with the same amount of extra milk, but expect a thinner, less rich result.
How do I make it lower in sugar?
Use unsweetened milk and unsweetened yogurt, and cut the Biscoff spread back to 1 tablespoon. The spice character will still come through, though less intensely sweet.
