Ingredients & Substitutes
Here are all ingredients needed, among with more details, tips and replacement options–precise quantities can be found in the recipe card at the bottom.
- Weetabix biscuits – Known as Weet-Bix in Australia and New Zealand, this is the base of the recipe. If you prefer, substitute with ⅔ cup of shredded wheat for a similar consistency or a mix of crushed Weetabix and rolled oats.
- Greek yogurt – You can use nonfat or full fat Greek yogurt, preferably plain and unsweetened. I recommend 2% Greek yogurt for a balance of taste, protein, and fewer calories. Swap with whipped cottage cheese, lactose-free Greek yogurt, or a thick dairy-free alternative. For better macros, use high protein yogurt instead.
- Milk of choice – I used unsweetened almond milk, it has few calories and no sugar. Feel free to choose any dairy or dairy-free milk you like, such as semi-skimmed milk, GMO-free soy milk, oat milk.
- Maple syrup – It adds natural sweetness with no refined sugar. Great replacements are honey, agave, date syrup, brown sugar or calorie-free alternatives such as monk fruit and erythritol.
How to make overnight Weetabix
You can find the printable recipe at the end of this blog post, but for now here’s an overview of how to make overnight Weetabix with step-by-step pictures.
- Step 1 – Crush Weetabix. Crush two Weetabix biscuits in a bowl until finely crumbled, or leave some chunks for more texture.
- Step 2 – Add liquids. Add Greek yogurt and start mixing, while pouring in up to ¼ cup (60 ml) of milk. Do not exaggerate with milk, as the Weetabix may get too mushy. Stir in 1 to 2 teaspoons of maple syrup to taste, until it reaches the desired sweetness.
- Step 3 – Portion out. Transfer the mixture into a jar, meal prep container, or serving bowl, smoothing out the surface with a spoon.
- Step 4 – Top. In a separate bowl, mix Greek yogurt with Biscoff spread until combined. Spread the cheesecake topping over the Weetabix base.
- Step 5 – Refrigerate. Cover and refrigerate overnight (or at least 2 hours) to let it soak.
- Step 6 – Serve. Before serving, top with sliced banana and some crushed Biscoff for more flavor and texture.
Dietary adaptations
- High protein – Add a scoop of protein powder and adjust the texture with a splash of extra milk. I really like making high protein overnight weetabix with vanilla whey, perfect as a post workout. As an alternative, swap Greek yogurt for protein yogurt and milk for protein milk.
- Low calorie – Prep your breakfast with 0% fat Greek yogurt, unsweetened almond milk or skimmed milk, and calorie-free sweeteners instead of maple syrup. When making low calorie overnight Weetabix, just be mindful about toppings.
- High calorie – Looking for high calorie breakfasts to gain weight and build muscle? Use 3 to 4 Weetabix biscuits with full fat Greek yogurt and milk, adding a scoop of protein powder and healthy high calorie foods like peanut butter and dates.
- Low carb – Swap one Weetabix biscuit for a scoop of protein powder, sweeten with sugar-free sweeteners, and limit high carb toppings. For fewer carbs, use unsweetened almond milk or soy milk and plain soy yogurt.
- Vegan – Replace Greek yogurt with plant based alternatives and dilute with nondairy milk. My girlfriend loves her overnight weetabix with soy yogurt and oat milk, all topped with sliced strawberries.
7 overnight Weetabix flavors
- Biscoff Cheesecake – Mix Biscoff spread into Greek yogurt before layering it on top of your weetabix. For the complete experience, serve sprinkled with crushed Biscoff biscuits and sliced banana.
- Fruity – Stir in chopped strawberries, blueberries, mixed berries or sliced banana. Before serving, top with more fruit, fruit compote or sugar-free jam if desired.
- Chocolate – Mix in the Weetabix a tablespoon of unsweetened cocoa powder. For more flavor, top with dark chocolate chips or cocoa nibs.
- Nutella – Add a swirl of Nutella into the Weetabix mixture. To keep sugars and hydrogenated fats low, use a natural hazelnut spread or try my low calorie Nutella recipe.
- Banoffee – Combine mashed banana with a drizzle of caramel sauce (try my keto caramel sauce) and stir it in along with chopped nuts.
- Tiramisu – Mix in a teaspoon of instant coffee, then serve with a layer of Greek yogurt and a sprinkle of cocoa powder.
- Carrot cake – Stir in grated carrot, a pinch of cinnamon, a dash of vanilla extract and a touch of nutmeg. Top with crushed walnuts and a drizzle of honey or maple syrup before serving.
Recipe tips
- Be mindful about added sugars – To keep sugars and calories down, it’s best to use plain Greek yogurt and unsweetened milk. Flavored dairy products are often loaded to the brick with sugars, so I’d rather give a glance at the ingredient list if using them.
- Don’t add too much liquid – If you mix the biscuits with too much milk or yogurt, they’ll easily get soggy. For two biscuits I recommend ½ cup (120 g) of Greek yogurt and ¼ cup (60 ml) of milk.
- Eat within 1 day – Although you can make it up to 3 days in advance, it’s best to make Weetabix porridge overnight and eat it the next morning. The longer it sits in the fridge, the mushier it gets.
- Add toppings before serving – Crunchy or fresh toppings should be added right before having breakfast, otherwise they’d lose taste and texture. For my Biscoff Weetabix cheesecake, I added the yogurt layer before refrigerating but then topped with banana and crushed Lotus in the morning.
- Customize the recipe – What’s so good about a Weetabix porridge is that you can easily customize it to match your preferences. From protein powder to flavors, you’ll be able to whip up your own breakfast.
Make ahead & Storage
This overnight Weetabix recipe is perfect for meal prepping! Make it the night before for a ready-to-eat healthy breakfast in the morning, or prep a larger batch on the weekend for the week ahead. Here are all details about storage.
After stirring, place the mixture into a sealable mason jar or an airtight container and refrigerate. It will last for up to 3 days in the fridge, but for the best taste and texture it’s best to serve it within 24 hours. I recommend preparing it in the night after dinner and eat it the next morning. Freezing is not recommended, as the texture can become quite soggy when thawed.
