Quick Biscoff Overnight Oats

My roommate used to keep a jar of Biscoff in our pantry that she treated like gold dust, and I honestly did not understand the hype until one sleepy Monday morning when I desperate for something breakfast-like and found nothing but oats and that suspiciously small jar of cookie butter.

Now I make these on Sunday nights while the kettle boils, and something about opening the fridge to those ready waiting jars makes Tuesday feel significantly less terrible than it actually is.

Ingredients

• 1 cup rolled oats: Use old fashioned rolled oats here rather than instant or steel cut since they soften perfectly overnight without turning into mush or staying too chewy
• 1 cup milk dairy or non-dairy: Whatever milk you actually like drinking works here, and I have found oat milk creates the creamiest result but almond is perfectly fine
• 1/2 cup plain Greek yogurt: This adds protein and makes the texture incredibly lush, though regular yogurt works if that is what you have
• 2 tbsp Biscoff spread: Warm this slightly in the microwave for 15 seconds before stirring it in so it incorporates evenly instead of staying in stubborn little clumps
• 1 to 2 tsp maple syrup or honey optional: The cookies and spread bring plenty of sweetness, but add this if you know you like things on the sweeter side
• 1/2 tsp vanilla extract: Do not skip this because it bridges the gap between cookie butter flavor and regular oats
• Pinch of salt: Just enough to make everything taste more like itself

Instructions

Mix everything together:

Combine all ingredients except toppings in a medium bowl and stir until no streaks of yogurt or Biscoff remain visible, which takes about a minute of serious stirring

Divide into jars:

Pour the mixture evenly between two jars or containers, leaving about an inch at the top since the oats expand slightly overnight

Refrigerate overnight:

Cover tightly and let them chill for at least 6 hours, though 8 to 12 is even better for the softest texture

Add toppings and serve:

Give the oats a good stir in the morning, crush the cookies directly over the jars, drizzle with melted Biscoff, and add fruit if you feel like pretending this is a balanced breakfast

Save

My partner accidentally ate my prepped jar once and looked so guilty I pretended it was fine, then I had to eat plain toast for breakfast and it was absolutely not fine.

Making Ahead

These keep perfectly for two days in the fridge, so doubling the batch on Sunday means you are set until Tuesday morning with zero effort.

Texture Tips

If you prefer thinner oats, add another splash of milk before refrigerating, and if you like them almost like pudding, reduce the milk slightly.

Topping Variations

Beyond the classic crushed cookies, try chopped toasted pecans, a dollop of peanut butter swirled on top, or fresh sliced bananas for something that feels almost healthy.

• Warm the finished oats in the microwave for 30 seconds if cold breakfast is not your thing
• Use cookie butter from other brands if Biscoff is not available at your store
• Mason jars with wide mouths make stirring and eating so much easier

Save

There is something genuinely lovely about waking up to breakfast that is already waiting for you, like you did a favor for your future self.

Recipe FAQs

→ How long do these oats keep in the refrigerator?

These overnight oats stay fresh for up to 2 days when stored properly in airtight containers. The textures remain optimal within this timeframe, though the cookies may soften slightly.

→ Can I make this dairy-free?

Absolutely. Substitute regular milk with almond, oat, or coconut milk, and swap Greek yogurt for a plant-based alternative. The Biscoff spread is naturally dairy-free.

→ What's the minimum chilling time required?

You'll need at least 6 hours in the refrigerator for the oats to properly absorb the liquid and soften. Overnight chilling (8-10 hours) yields the best creamy consistency.

→ Can I heat these oats instead of eating them cold?

You can gently warm them in the microwave for 30-60 seconds if you prefer hot oats, though the Biscoff spread will melt and change the texture. They're designed to be enjoyed chilled.

→ What toppings work well with Biscoff oats?

Fresh banana slices, strawberries, or blueberries complement the caramelized flavor beautifully. Chopped pecans, walnuts, or extra crushed Biscoff cookies add wonderful crunch.

→ Is this suitable for meal prep?

Perfectly suited. Make 2-3 jars at once and keep them refrigerated for grab-and-go breakfasts throughout the week. Just add fresh toppings right before serving.
