Why Biscoff Overnight Oats Are SO Good:

  • They taste like cookie butter!
  • Biscoff cookies are sweet, crunchy, and full of cozy brown sugar and cinnamon flavor – which pair perfectly with oats!
  • Cookie butter overnight oats are actually a pretty balanced breakfast, with the addition of protein-rich Greek yogurt and collagen peptides for protein.
  • Need a little more protein? You can easily customize these overnight oats to your own needs and preferences by adding some vanilla or unflavored protein powder or collagen peptides.
  • Overnight Biscoff oats are pretty low-maintenance to make. You just need a few minutes, then the magic happens when they set in the fridge overnight (or for a few hours).

Ingredients You Will Need

For a full ingredient list and amounts, check the recipe card at the bottom of this post.

ingredients to make Biscoff overnight oats
  • Oats: Use old-fashioned oats, certified gluten-free if that’s a concern. You can use quick oats in overnight oats, but it changes the liquid/ oat ratio and final texture a bit.
  • Greek Yogurt: adds protein and makes the cake batter overnight oats extra creamy.
  • Chia & Flax Seeds: these seeds add fiber, healthy fats, and helps create the perfect overnight oats consistency.
  • Cookie Butter: Cookie butter, or Biscoff spread, adds a delicious, creamy, sweetness to the overnight oats.
  • Almond Milk: Feel free to sub dairy milk, oat milk, soy milk, or whatever you prefer.
  • Brown Sugar: the perfect sweetener to pair with cookie butter and Biscoff flavors! If you need a no or low sugar option, try using a substitute like Truvia Sweet Complete Brown Sugar Replacement (I’ve used it in these oats with success!).
  • Cinnamon: a little extra cinnamon enhances the cookie butter flavor.
  • Biscoff Cookie: while this is a little extra and not mandatory, a crumbled Biscoff cookie is the perfect garnish that adds a little extra flavor and crunch to these overnight oats!
  • Collagen Peptides: You don’t have to include if you don’t like it, but it’s an easy, unflavored way to boost protein. You can also use a scoop of your favorite vanilla or unflavored protein powder. Check out my collagen article to better help you decide if it’s for you.

Step-by-Step Directions

ingredients to make overnight biscoff oats in a jar
  1. Stir the cookie butter and other wet ingredients in the mason jar, until smooth.
  2. Add the dry ingredients and stir until combined.
  3. Wait 5 minutes, then stir again (this helps create clumps of seeds from settling).
  4. Transfer to a fridge and let set overnight, or at least 4 hours.
  5. Stir after refrigerating, then garnish with a crumbled Biscoff cookie and enjoy.

Expert Tips & Variations

  • If you’re struggling to incorporate the cookie butter into the oats, try mixing the cookie butter spread into the liquid ingredients first, then add the dry ingredients.
  • I always recommend waiting 5 minutes, then stirring again before refrigerating when making overnight oats. The reason is that this lets the mixture start to slightly thicken, so when you re-stir it helps prevent the seeds from settling on the bottom of the jar.
  • Sugar-Free: While there is a small amount of added sugar in the cookie butter and Biscoff cookie, you sub your favorite sugar-free sweetener of choice and use unsweetened Greek yogurt and milk.

My oats are too thick/ thin, what do I do?

Change the texture by changing the amount of liquid. I like my oats on the thicker side as a personal preference, but also because it’s easier to adjust the consistency when they’re starting out thicker. Just add a little extra milk in the morning before eating, if your oats are too thick for your liking!

Do you eat overnight oats warm or cold?

Overnight oats are typically eaten cold, but you can enjoy them warm, too. Heat your overnight oats (remove any metal lids!) for 30-60 seconds, then stir. Continue adding 10-15 seconds at a time, then stirring, until your overnight oats reach your desired temperature.

Are overnight oats safe to eat since you’re not cooking the oats?

Yes. You may hear concern over the phytic acid in oats, as it’s sometimes called an “anti-nutrient,” since phytic acid can slightly inhibit the absorption of some nutrients (iron, zinc, and calcium). But this effect is mostly limited to what you’re eating at that current meal.

Additionally, research has shown us that phytic acid is rarely a concern if you’re eating enough and an overall balanced diet.
