• Old Fashioned Rolled Oats: These are the star of the show. Rolled oats provide the ideal texture for overnight oats – soft, chewy, and substantial without becoming mushy. Avoid instant or quick oats, as they tend to absorb liquid too quickly and can result in a gluey consistency. Steel-cut oats also work but require more liquid and result in a chewier texture.
• Milk: The liquid base for your oats. You can use any type of milk you prefer. Whole cow’s milk will yield a richer, creamier result, while dairy-free alternatives such as almond milk, oat milk, or soy milk are excellent choices for a vegan version or if you’re avoiding dairy. Each milk type contributes a slightly different flavor profile, so feel free to experiment.
• Biscoff Cookie Butter: The key ingredient for that signature spiced caramel taste. This creamy spread is what makes these oats so special. Lotus Biscoff is the most well-known brand, but you can find similar speculoos cookie butter spreads from other brands like Trader Joe’s or even make your own. For a smoother mix, consider gently warming it before adding.
• Chia Seeds: A powerhouse ingredient! Chia seeds are essential for achieving the perfect thick, pudding-like consistency that makes overnight oats so satisfying. They absorb liquid, swell, and create a gel-like texture, binding all the ingredients together. They also boost the fiber and omega-3 content.
• Brown Sugar: Adds a touch of caramel sweetness that beautifully complements the Biscoff flavor. Packed brown sugar is preferred for its moist texture and deeper molasses notes, but granulated sugar can be used in a pinch. Adjust the quantity to suit your preferred level of sweetness.
• Pure Vanilla Extract: A splash of vanilla enhances all the other flavors, adding a warm, aromatic depth that makes the oats taste even more indulgent.
• Cinnamon: A pinch of ground cinnamon further amplifies the inherent spice flavors present in the Biscoff cookie butter, tying all the comforting notes together for a truly harmonious blend.
• Kosher Salt: Just a tiny pinch makes a big difference! Salt balances the sweetness and brings out the full spectrum of flavors, preventing the oats from tasting flat.

Delicious Serving Suggestions:

While delicious on its own, these overnight oats truly shine with a medley of toppings. Get creative and customize your bowl for extra texture and flavor!

• Crumbled Biscoff cookies for an extra crunch and intense cookie flavor.
• A sprinkle of extra cinnamon or a dash of pumpkin spice.
• Toasted and chopped hazelnuts, pecans, or almonds for nutty notes.
• Fresh berries like strawberries, raspberries, or blueberries for a burst of freshness.
• A dollop of vanilla yogurt (dairy or non-dairy) for added creaminess and a tangy contrast.
• Mini chocolate chips for a touch of chocolatey indulgence.
• A drizzle of extra cookie butter or maple syrup.

Refer to the recipe card below for precise quantities and detailed instructions.

Step 1: Combine All Ingredients. In a 16-ounce mason jar, bowl, or food storage container, add your rolled oats, milk, Biscoff cookie butter, chia seeds, brown sugar, vanilla extract, cinnamon, and kosher salt.

Tip for Easier Mixing: If your Biscoff cookie butter is particularly thick or cold, you can melt it in the microwave for about 10-15 seconds before adding it to the other ingredients. This will help it mix through the oats and milk much more smoothly, ensuring an even distribution of that delicious flavor.

Step 2: Mix Thoroughly. Stir all the ingredients together vigorously until they are thoroughly combined. Pay special attention to breaking up any clumps of chia seeds, ensuring they are evenly distributed. This is crucial for the oats to absorb the liquid uniformly and achieve a consistent texture. Once mixed, cover your container tightly.

Step 3: Refrigerate Overnight. Place the covered container in the refrigerator overnight, or for a minimum of 4 hours. This allows the oats to soften and the chia seeds to swell, creating that signature creamy consistency. The longer they chill, the thicker and more flavorful they become.

Step 4: Stir and Serve. The next morning, or after the minimum refrigeration time, remove your oats from the fridge. Give them a good stir. If the mixture is too thick, you can add a splash more milk to reach your desired consistency. Now, it’s time for the fun part – add your favorite toppings and enjoy your perfectly prepped, delicious breakfast!

Substitutions and Creative Variations

One of the best aspects of overnight oats is their incredible flexibility. Don’t have an ingredient? Want to try something new? Here are some fantastic substitution and variation ideas:

• Oats: While old-fashioned rolled oats are highly recommended for their perfect texture, you do have options.
  • Steel-Cut (Irish) Oats: These can be substituted for a chewier, heartier consistency. Note that steel-cut oats absorb liquid more slowly and may require a little extra milk or a longer soaking time for optimal softness.
  • Quick Oats: Generally, quick oats are not recommended as they tend to become overly soggy and mushy when soaked overnight, leading to a less appealing texture.
• Biscoff Cookie Butter: The star flavor!
  • Lotus Biscoff is the original and most popular brand.
  • Alternatives: Many stores offer their own versions, such as Trader Joe’s Speculoos Cookie Butter and Great Value Speculoos Cookie Butter from Walmart.
  • Homemade: Feeling ambitious? You can even make your homemade cookie butter for a truly custom flavor.
• Milk: The beauty of overnight oats is that almost any milk works!
  • Use traditional cow’s milk for a classic taste.
  • For a dairy-free and vegan option, choose your preferred plant-based milk like almond milk, oat milk, soy milk, cashew milk, or even coconut milk for a tropical twist.
• Sweetener: Adjust the sweetness to your liking.
  • In place of brown sugar, you can use other liquid sweeteners. Maple syrup is an excellent alternative, offering a rich, earthy sweetness. Since maple syrup is often sweeter than sugar, start with ½ tablespoon, taste, and add more if needed.
  • Honey (not vegan) or agave nectar are also great options.
  • For a sugar-free alternative, consider a sugar substitute or a few drops of stevia, adjusting to taste.
• Extra Spices: Enhance the warm spice profile by adding a tiny pinch of ground ginger, cloves, or nutmeg alongside the cinnamon.

Dietary Considerations and Special Tips

These cookie butter overnight oats can be adapted to various dietary needs, making them accessible and enjoyable for many.

• Vegan: This recipe is incredibly easy to make fully vegan. Simply ensure you use a non-dairy milk alternative (such as almond, oat, or soy milk). Good news for cookie butter lovers: Biscoff spread itself is a naturally vegan product, making this a truly delightful plant-based breakfast!
• Gluten-Free: Achieving a gluten-free version of this recipe presents a slight challenge. While you can easily use certified gluten-free rolled oats, the main hurdle is the cookie butter itself. Traditional speculoos cookies (from which cookie butter is made) contain wheat flour. Therefore, this recipe, as written with standard cookie butter, is not gluten-free.
  • Solution: To make it truly gluten-free, you would need to use homemade gluten-free cookie butter, made from gluten-free speculoos cookies or a similar spiced biscuit. This would ensure the entire dish is suitable for a gluten-free diet.

Yes! In addition to the famous Biscoff cookies, Lotus Biscoff cookie butter is also entirely vegan. This makes it a fantastic ingredient for plant-based diets.

The best milk for overnight oats truly comes down to personal preference. Any type of milk works wonderfully, including dairy options like cow’s milk (whole, 2%, or skim) or various non-dairy alternatives such as almond milk, oat milk, soy milk, or coconut milk. Oat milk and whole cow’s milk tend to yield the creamiest results.

Absolutely! While traditionally enjoyed cold, you can gently warm your Biscoff overnight oats in the microwave for 30-60 seconds (or on the stovetop over low heat) if you prefer a warm breakfast. Stir well after heating. Be mindful that heating may alter the texture slightly, but the flavor will remain delicious.

It’s generally not recommended to use quick oats for overnight oats. Quick oats are pre-cooked and rolled thinner, causing them to absorb liquid too quickly and result in a mushy, less appealing texture when left to soak overnight. Old-fashioned rolled oats hold their shape better and provide a satisfying, chewy consistency.

If your overnight oats are too thick, simply stir in a tablespoon or two of extra milk until you reach your desired creamy consistency. If they are too thin (which is less common with this recipe due to chia seeds), you can add another half teaspoon of chia seeds and let them sit for another 30 minutes to an hour to thicken further.
