This overnight Weetabix recipe is one of my go-to make-ahead breakfasts. It takes five minutes to prep, you don’t need to cook anything, and it’s actually filling thanks to the Greek yogurt. It’s thick, creamy, and way better than just soaking Weetabix in milk. It’s packed with protein, easy to customize, and perfect for meal prep or busy mornings.

Ingredients You’ll Need

No fancy ingredients here—just a few basics that hit when they come together.

• Weetabix biscuits – Crushed up for the base. You can also sub with shredded wheat or a bit of oats.
• Greek yogurt – I go for 2% for the perfect mix of creamy and macro-friendly, but anything works.
• Milk – Almond, oat, regular, protein milk… pick your fave.
• Maple syrup – For sweetness. Use honey, agave, or your sweetener.
• Biscoff spread – Optional but highly recommended for the dessert-for-breakfast moment.
• Toppings – Crushed Biscoff, banana slices, fruit, granola… go wild.

How to Make Overnight Weetabix

Here’s how I make it step-by-step—it takes like 5 minutes tops.

I toss two biscuits into a bowl and crush them up with a fork. I like a mix of fine and chunky for texture.

I add my Greek yogurt, then pour in a splash of milk (about ¼ cup). Stir it up until it’s thick but smooth. If I want it sweeter, I mix in a little maple syrup here too.

Once it’s all mixed, I spread the Weetabix mixture into a jar or container and smooth the top with a spoon.

In a separate bowl, I stir Biscoff spread into some yogurt and then spread that on top like a cheesecake layer.

I cover the container and let it sit in the fridge overnight (or at least 2 hours if I’m impatient).

In the morning, I throw on some sliced banana and crushed Biscoff cookies. And yes, it’s just as good as it sounds.

Dietary Adaptations

Overnight Weetabix is one of those recipes you can tweak to fit whatever you’re working toward.

• High protein: Add a scoop of your favorite protein powder and thin it out with a little extra milk. I love using vanilla whey for a post-workout version. You can also swap in protein yogurt and protein milk for a serious macro boost.
• Low calorie: Stick to 0% fat Greek yogurt, unsweetened almond milk, and calorie-free sweeteners like monk fruit or stevia. And go easy on the toppings if you’re watching extras.
• High calorie: Want something more filling? Use 3 to 4 Weetabix biscuits, full-fat Greek yogurt, protein milk, and toss in extras like peanut butter, dates, or granola for extra energy.
• Low carb: Cut one of the Weetabix biscuits and replace it with protein powder. Use sugar-free sweeteners and low-carb toppings, and stick to unsweetened almond milk or soy milk with plain soy yogurt.
• Vegan: Super easy—just use plant-based yogurt (like soy or coconut) and nondairy milk. My girlfriend swears by the oat milk + soy yogurt combo, especially with sliced strawberries on top.

Overnight Weetabix Flavor Ideas

If you get bored easily (same), here are 7 flavor combos to keep breakfast exciting:

• Biscoff Cheesecake – Stir Biscoff into your yogurt layer and top with crushed Biscoff cookies and sliced banana.
• Fruity – Add fresh strawberries, blueberries, or any mixed berries. Top with fruit compote or sugar-free jam.
• Chocolate – Mix cocoa powder into the base, then top with dark chocolate chips or cocoa nibs.
• Nutella – Swirl Nutella into the base or topping. Want a healthier twist? Use a clean hazelnut spread or low-cal Nutella alternative.
• Banoffee – Mix mashed banana and a drizzle of caramel sauce into the base, then top with chopped nuts.
• Tiramisu – Add a teaspoon of instant coffee to the Weetabix, top with thick yogurt, and finish with a dusting of cocoa powder.
• Carrot Cake – Stir grated carrot, cinnamon, vanilla, and nutmeg into the base. Top with crushed walnuts and a little honey or maple syrup.

What to Serve With Overnight Weetabix

I usually just grab a jar and eat it straight from the fridge, but if I’m feeling extra, I’ll add a hard-boiled egg, a protein coffee, or a scoop of peanut butter on top. It’s also great paired with my protein granola bars or a banana protein smoothie for a complete meal.

Make Ahead & Storing Overnight Weetabix

This recipe is perfect for make-ahead mornings. I usually prep a few jars at a time so breakfast is ready and waiting. Just mix everything, layer it into a jar or container, and keep it in the fridge.

It stays good for up to three days, but I think it’s best within the first day when the texture is thick and creamy. After that it gets a little too soft for my taste.

I don’t recommend freezing it. The texture turns weird and mushy once it thaws. Definitely better fresh from the fridge.
