I am always on the lookout for delicious and healthy breakfast options, and this easy overnight Weetabix recipe checks all the boxes for me!

It’s loaded with nutrients, yet still satisfies sweet cravings. You may have seen other overnight Weet-bix recipes on social media, as it has become a Tik Tok food trend! But like many food trends that I have seen online, I am always looking for ways to modify it for a healthier option. 

This overnight breakfast Weetabix takes basic ingredients and enhances the flavors with 7 different mix-in choices, so you can pick what is best for you!

Weetabix overnight oats will quickly become a go-to breakfast in your home. My kids love it and request it often, so I can confidently say that this will please adults and kids alike.

In the recipe below, I’ll take you through the steps of making a Biscoff overnight Weetabix for all you Biscoff lovers out there, but you can easily modify this recipe (see my flavor variations section below)! 

If you’re like me, you want easy breakfasts that take no prep time in the morning. I’m a huge fan of overnight oats, which is why I love this overnight Weetabix recipe so much because it’s a fun way to change things up from your morning oatmeal!

Overnight Weetbix, or Weetabix, is kind of like overnight oats using Weetabix. I take Weetabix breakfast cereal, soak it in milk overnight, and layer it with fun toppings like yogurt, fresh fruit, sweet mix-ins, etc.

Weetabix is a classic cereal that comes in a larger biscuit form. So, similar to oats, when mixed with milk, it will begin to soften and can be broken apart into bite size pieces. The main difference is that with when making Weetabix overnight, you only need to soak the Weetabix and milk, but then the rest of the toppings can be layered on top when you’re ready to eat it, vs. mixed in as you would with overnight oats.

My kids devour this healthy breakfast recipe, and they look forward to adding in all of their favorite toppings! It’s a great way to get your kids to eat more whole grains and plant protein.

This Weetabix with milk super customizable too, so you can easily meal prep a huge batch of the base, and let each person in your family add different toppings to satisfy their preferences. I have 7 different topping ideas that I share later in this post!

This recipe is great for anyone who needs a healthy breakfast on busy mornings: it will only take 5 minutes of prep time with only 3 main ingredients for the base. From there, you can play around and make this recipe as simple or elaborate as you’d like!

🥘 Ingredients

Made with simple ingredients, this overnight Weetabix with yogurt and milk comes together quickly and easily! See the recipe card at the bottom of the page for the exact measurements.

Ingredients for overnight Weetabix recipe on a white background.

Weetabix Biscuits: I used crushed Weetabix as the base for this nutritious breakfast. These wheat biscuits have been made in the United Kingdom since the 1930s! (In the US and UK it’s called Weetabix, in Australia it’s called Weet-Bix). I don’t recommend swapping this out, since it’s the base of the whole recipe, but you could use plain shredded wheat squares if you’re in a bind.

Milk: Milk and Weetabix go hand in hand! Cow’s milk is most commonly paired with Weetabix cereal, but any type of milk will work for this recipe. Whole milk, low fat milk, non fat milk, or a plant based milk like oat milk, or almond milk would all be a good option.

Maple Syrup: Maple syrup will add the best touch of sweetness to your Weetabix base without loading up on refined sugars. Sometimes I will substitute the maple syrup for honey or agave syrup for a slightly different flavor. Coconut sugar would work well too.

Banana: Banana is the perfect topping for these Weetabix overnight oats! It is creamy, sweet, and layers well. I will sometimes mix in berries or other fresh fruits too!

Greek Yogurt: I like using Greek yogurt since it’s higher in protein, but you can use vanilla yogurt or plain yogurt too. Non-dairy yogurt would be a great vegan option. While you can make this Weetabix without yogurt, I wouldn’t recommend it because the yogurt does add a nice creamy texture!

Biscoff Spread & Biscoff Cookie Crumble: Adding in Biscoff spread and cookies takes this breakfast to a whole new level! Nut butter would be a healthier substitution here!

🔪 How To Make Overnight Weetabix

Follow along with these detailed instructions to learn how to make overnight Weet-bix. You can make it exactly as is, or modify it after combining the base ingredients with one of the other flavor variations down below.

Combine Ingredients: First, I’ll crush the Weetabix biscuits and spread it into the bottom of a container. Then I’ll pour over the maple syrup and milk. Make sure to stir to combine.

Layer Ingredients: Press down with the back of a spoon to form an even layer. Top with sliced banana.

Make Yogurt Mix: In a separate bowl mix together the yogurt and melted Biscoff spread.

Add Toppings: Spread in an even layer over the sliced bananas.

Chill & Serve: Finish by sprinkling crushed Biscoff cookies over the top of the yogurt layer. Cover with a lid and refrigerate overnight or for at least 2 hours.

Serve and enjoy!

My #1 Secret Tip for this recipe is to make sure you use the right ratio of liquid to Weetabix to get the absolute perfect consistency! Too much liquid will make this runny, too little liquid and you’ll end up with a super thick, clumpy cereal.

A good rule of thumb is about 1/4 cup liquid per Weetabix biscuit that you use. You also want to make sure you stir the Weetabix mixture thoroughly before refrigerating so that the milk gets distributed evenly.

Other Tips To Keep In Mind:

  • Avoid Mess: You can crush the Weetabix biscuits in a zipped plastic bag to avoid any mess from crumbs. Alternatively, you can crush the biscuits once they have been combined with the milk, in the container itself.
  • If You Can’t Refrigerate Overnight, let this sit for at least 2-3 hours in the fridge before serving so the flavors can combine and the base can set.
  • Double Or Triple Batch: Since this breakfast Weetabix will keep for 2-3 days, you can double or triple the recipe to make more servings for a quick and easy make ahead breakfast.

📖 Overnight Weetabix Flavor Ideas

One of my favorite things about this recipe is how many ways you can change it up! These are my top 7 flavor combinations to try:

  1. Tropical: Mix fruit such as mango, papaya and kiwi into the Greek yogurt instead of the Biscoff spread. Top with passion fruit mixed into coconut yogurt instead of the crushed cookies.
  2. Chocolate: Mix cocoa powder into yogurt and top the Weetabix base. Then make a chocolate layer with chocolate nutella (or try this vegan Nutella). Top with chocolate chips, crushed hazelnuts, and crumbled chocolate cookies.
  3. Peanut Butter And Banana: Drizzle peanut butter into the yogurt layer, sweeten with maple syrup and top with a layer of sliced banana and peanut butter granola.
  4. Mixed Berries: Replace the bananas with a layer of mixed frozen or fresh berries. You can also just use strawberries for more of a strawberry Weetabix cheesecake type of feel!
  5. Cinnamon: Stir ¼ tsp cinnamon through the Greek yogurt and top the Weetabix base.
  6. Oreo Cookie: Crush Oreo cookies and mix through yogurt and finish with a top layer of more crushed cookies and mini chocolate chips.
  7. Overnight Weetabix With Protein: Add a scoop of vanilla protein powder to the Greek yogurt and spread in an even layer over the Weetabix base. Top with your favorite berries! Add a bit of vanilla extract for extra vanilla flavor.

🍽 Serving Suggestions

I typically will just enjoy overnight Weetabix cereal on its own, with any of the flavor variations above. Occasionally I’ll serve it with coffee or tea: I love sipping on a beetroot latte or Biscoff latte for a relaxing morning!

When I’m serving a larger crowd, I’ll oftentimes pair it with some of these other healthy vegetarian breakfast ideas for a larger, filling breakfast.

🙌 Dietary Adaptations

This recipe can be easily adapted to meet dietary needs, and I’ve made this vegan and lower in sugar with success!

Vegan Option: To make this into a dairy-free, vegan overnight Weetabix recipe, I recommend using plant-based alternatives like coconut yogurt and unsweetened almond milk instead of Greek yogurt and cow’s milk.

Lower Sugar Option: If you prefer to make a low sugar overnight Weetabix, omit the maple syrup, Biscoff cookies, and use your favorite nut butter instead of the Biscoff spread. You’ll still get great flavor, but with way less added sugar.

Gluten-Free Option: For a gluten-free version, you’ll have to replace the Weetabix with oats, use peanut butter instead of the Biscoff spread, and use a gluten free cookie option for the crumble topping.

🫙 Storage Directions

Refrigeration: You may store these Weetabix overnight oats in an airtight container in the fridge for up to 2-3 days. While it does keep that long, I have noticed that it tastes the best within 24-36 hours of making it. Make sure to keep toppings separate for the best texture and freshness and add right before consuming.

Freezer: I don’t recommend freezing this recipe as the texture will completely change when defrosted.

❓Recipe FAQs

Can overnight weetabix be served warm?

Yes! While I will often eat this straight out of the fridge or at room temperature, you can absolutely serve this warm! Just heat it slightly in the microwave for up to 60 seconds until it reaches your desired temperature. Make sure you add the toppings after you have warmed it up!

What is the best liquid to use?

The key to making this recipe is to use some type of milk! Regular cow’s milk or any plant-based milk will work. Don’t use water, coconut water or any other type of liquid – stick to milk and milk-varieties. Depending on how creamy you want this to be, you can use a fuller-fat milk like whole milk or coconut milk; or for a lighter option go with unsweetened almond milk or 1% cow’s milk.

When is the best time to add the toppings?

I recommend adding the toppings right before you’re planning to serve this! While you can add the toppings and mix them in with the Weetabix and milk, but they will end up “melting” into the Weetabix by the time you’re ready to serve. You’ll get the flavor but none of the texture. So just add them before serving!


Yes, you could serve this overnight Weetabix to a baby or toddler, as long as they are eating solids. For a baby, be sure to allow the Weetabix to soak in the milk until fully softened. Also, if you’re serving this to kids, babies, or toddlers, I recommend leaving out the Biscoff altogether and adding in healthy fruits and nut butter for a healthy kids breakfast option.
