Tips for Perfect Overnight Oats

This is a super simple breakfast, but I have a few tips to make it absolutely perfect!
Tip 1: Choose the Right Oats
Use old-fashioned rolled oats, not quick oats or steel-cut. Quick oats will become too mushy, while steel-cut won’t soften enough overnight.
Tip 2: The Perfect Ratio
Start with a 1:1 ratio of oats to milk, then adjust to your preferred thickness. Remember that the oats will continue to absorb liquid overnight.
Tip 3: Don’t Skip the Yogurt
Greek yogurt makes these oats extra creamy and adds protein to keep you full longer. Plus, it adds a slight tanginess that balances the sweet cookie butter perfectly.
Recipe FAQs
Can I Warm These Up?
While overnight oats are typically eaten cold, you can definitely warm them up! Just pop them in the microwave for 30-60 seconds. Add the cookie crumbles after heating.
How Long Do These Keep?
These will stay fresh in the refrigerator for up to 5 days, making them perfect for meal prep. Just wait to add the cookie topping until right before eating.
Can I Use Another Type of Cookie Butter?
Yes! While Biscoff gives that classic caramelized spice flavor, any cookie butter or even peanut butter will work. Each will give its own unique twist to the recipe.
Can I Add Other Toppings?
Absolutely! Try sliced bananas, a drizzle of caramel, chocolate chips, or a sprinkle of cinnamon. Make it your own!
Can I Make These Dairy-Free?
Yes! Use your favorite plant-based milk and dairy-free yogurt. Biscoff spread is already vegan-friendly!
These Biscoff overnight oats are perfect for busy mornings when you want something that feels like a treat but keeps you energized all morning. The best part? You can prep several jars on Sunday and have breakfast ready to grab all week long!
Remember – don’t be afraid to swirl in extra cookie butter… I won’t tell anyone! 😉

Biscoff Overnight Oats
Ingredients
- 1/2 cup rolled oats use thick-cut for a hearty texture after soaking
- 1/2 cup milk regular or plant-based, like almond or oat milk
- 1/4 cup plain or Greek yogurt adds a creamy texture and slight tang
- 1 tablespoon Biscoff spread mixed into the oats for rich flavor
- 1 –2 teaspoons agave syrup or honey optional, for extra sweetness
- 1 tablespoon Biscoff spread for topping before serving
- 1 tablespoon crushed Biscoff cookies for sprinkling
- 1 whole Biscoff cookie for garnish
Instructions
- Prepare the oat base: In a deep bowl or small jar, mix the oats, milk, and yogurt. Stir well to evenly distribute the yogurt, creating a creamy base texture for your overnight oats.
- Add Biscoff spread: Stir in 1 tablespoon of Biscoff spread, mixing thoroughly to dissolve it into the milk mixture. The Biscoff adds warm spices and a rich caramel taste that infuses into the oats overnight.
- Sweeten (optional): If a sweeter flavor is desired, add 1–2 teaspoons of agave syrup or honey, stirring again to combine all ingredients evenly.
- Chill overnight: Cover the bowl or close the jar with a lid and refrigerate overnight, or for at least 6 hours. This allows the oats to absorb the liquid, soften, and soak up the Biscoff flavor.
- Morning prep: In the morning, take the oats out of the refrigerator. If the texture is too thick, add a splash of milk to reach your preferred consistency, stirring to incorporate.
- Top with Biscoff spread: For an extra indulgent layer, drizzle 1 tablespoon of Biscoff spread over the top. To make spreading easier, briefly microwave the Biscoff spread (a few seconds) to slightly soften it.
- Garnish with cookies: Sprinkle 1 tablespoon of crushed Biscoff cookies on top for a crunchy texture. Place a whole Biscoff cookie on the side or top for an appealing and decorative finish.
Notes
- Adjust sweetness: Taste the mixture before chilling and add a bit more agave or honey if you prefer it sweeter.
- Customize toppings: Try adding fresh fruits like banana slices or berries for added freshness and flavor.
- Make-ahead friendly: Double or triple the recipe to prepare multiple servings for the week ahead!
