What is Biscoff?
If you ask my children, they would say the Biscoff is the “airport cookies,” thanks to American Airlines. Coming from Belgium, Lotus Biscoff cookies (speculoos biscuits) gained worldwide popularity when American, Delta, and American Airlines started serving them on flights.
Recently, desserts, from cheesecakes to milkshakes made with Biscoff cookies, have gone viral on social media – and for a good reason! I love the combination of spices like cinnamon, nutmeg, ginger, allspice, and cloves. Lotus makes cookies and a spread that we’ve included in every part of our Biscoff overnight oats, and it’s a great way to use up any leftover cookies from your flight.
Key Ingredients
- Oats: The best type of oats for Biscoff overnight oats, or any overnight oat recipe for that matter, is old fashioned oats. Steel cut oats don’t absorb enough liquid and come out chewy and instant oats or quick oats end up quite mushy.
- Milk: You can use water or your milk of choice, like dairy milk, oat milk, soy milk, or coconut milk – like we do for our overnight oats with coconut milk. I prefer almond milk for this recipe because the nuttiness complements the flavor of the Biscoff cookies.
- Lotus Biscoff Cookies: The cookies sweeten the oatmeal without any other additions.
- Toppings: The toppings are optional, but melted Lotus Biscoff Cookie Butter (Lotus Biscoff spread) and crumbled Biscoff cookies make breakfast dessert in a cup.
How to Make Biscoff Overnight Oats
The full recipe with measurements is in the recipe card below.
Step 1: Pulse the Biscoff cookies in a food processor until crumbly, or crush the cookies in a plastic bag by hand. Transfer the cookies to an airtight container or glass jar and combine them with the rolled oats.
Step 2: Add the milk and stir to combine. Cover and refrigerate overnight (at least 2 hours).
Step 3: Remove the oats from the fridge and give it a good stir. Warm the Biscoff cookie butter in a microwave-safe bowl and drizzle it over the top of the oats.
Preparation Tip: You can also top the overnight oats with the melted cookie butter over the oats before you refrigerate if you prefer a Biscoff cookie butter shell.
Expert Tips
For the best Biscoff overnight oats, follow these helpful tips.
- For the best results, store the overnight oats in a jar with room to spare since the oatmeal expands as it rehydrates, and so will any mix-ins you add.
- I find a 1:1 ratio of one part old-fashioned oats and one part almond milk the best. Use less liquid if you want thicker oatmeal and more if you like it runny.
- Despite the name overnight oats, they only need to soak for 2-3 hours before you can enjoy them. However, the longer you soak the oats, the softer they will become.
- Give the mixture a good stir before adding toppings and digging in. If the oats seem dry after sitting in the fridge, add another splash of almond milk.

Frequently Asked Questions
Can I make this recipe in advance?
Absolutely! Overnight oats only need a minimum of 3 hours to set, and I highly recommend doubling the recipe at the beginning of the week for an easy-to-make grab-and-go breakfast you’ll love.
What is the ratio of oats to liquid for overnight oats?
People enjoy their oats in one of two ways. Some like oats to be thin and wet, whereas others want them thicker. I prefer mine thin, but I try to keep a good balance with each one of my overnight oat recipes, and I usually shoot for a 1:1 ratio of oats to liquid unless I am adding chia or basil seeds. For those recipes, I use a 1:2 ratio since they absorb more moisture.
If my recipe is too thin, I recommend adding a tablespoon of Greek yogurt to thicken the oats and increase the protein.
Do you eat overnight oats warm or cold?
Serve Biscoff overnight oats chilled straight from the fridge for a convenient, no-cook breakfast recipe that doesn’t need to be heated. However, if you’re craving something warm, microwave them for 30 seconds to a minute before adding the toppings.
Is Biscoff the same as speculoos?
Yes, Biscoff and speculoos refer to the same type of spiced shortcrust biscuit. Originating from Belgium, speculoo biscuits contain flour, brown sugar, butter or oil, and warm spices like cinnamon, ginger, cloves, and nutmeg.
The Lotus brand first commercialized them under the name Biscoff in 1932. Biscoff and speculoos are similar sweet and crunchy biscuits you can enjoy with coffee or tea. Get it – biscuits and coffee?

I tried this recipe when I was preggo and oh my GOODNESS… it tasted like dessert without all the naughty ingredients and insane amounts of sugar. This is going to be a postpartum must have for a quick breakfast that supports my milk supply, is nutritious and that tastes amazing.
