Ingredients needed
These are the ingredients you’ll need to make these PB&J Overnight Weetbix. You can find the exact measurements in the recipe card at the bottom of this page.
Weetbix: Forms the base of the recipe, creating a soft, cake-like layer that absorbs the flavors of the toppings while adding fiber and texture.
Milk: Helps soften the Weetbix and create the perfect consistency for the base.
Greek yoghurt: Adds creaminess, protein, and a delicious tang that balances the sweetness of the berries.
Peanut butter: The star ingredient in the yoghurt layer, adding healthy fats, richness, and that classic peanut butter flavor.
Honey: Adds a touch of natural sweetness and helps bring the peanut butter yoghurt layer together.
Frozen berries: Create a simple homemade jam-like topping that adds sweetness, color, and plenty of fruity flavor.
Chopped peanuts: Sprinkled over the top for a delicious crunch that perfectly complements the creamy and jammy layers.
Ingredient substitutions
Weetbix: If you don’t have Weetbix, you can use another wheat biscuit cereal. The texture may vary slightly, but it will still create a delicious base.
Milk: Any milk works well in this recipe, including dairy milk, almond milk, oat milk, soy milk, or coconut milk.
Greek yoghurt: Regular yoghurt can be used instead, although the topping may be slightly less thick and creamy. For extra protein, stick with Greek yoghurt.
Peanut butter: Almond butter, cashew butter, or any nut or seed butter can be used in place of peanut butter.
Honey: Maple syrup works perfectly as an alternative and keeps the recipe fully plant-based.
Frozen berries: You can use raspberries, strawberries, blueberries, mixed berries, or even fresh berries if preferred.
Chopped peanuts: Swap these for chopped almonds, pecans, walnuts, or simply leave them out if you prefer.
Protein boost (optional): For a higher-protein version, mix 20-30g vanilla protein powder into the yoghurt layer and add a splash of extra milk if needed to keep it smooth.

Tips & notes
- Use a thick Greek yogurt: A thick Greek yogurt will give you the creamiest texture and help create distinct layers that hold up well overnight.
- Adjust the sweetness to your taste: Depending on the sweetness of your berries, you may want to add a little extra honey to the yogurt layer.
- Let the berries cool slightly: Allowing the berry mixture to cool before layering helps keep the yogurt layer thick and creamy.
- Don’t skip the chilling time: While you can enjoy it after an hour, leaving it overnight gives the best texture and allows the flavors to develop.
- Add extra protein if you’d like: Mix vanilla protein powder into the yogurt layer for an extra protein boost. You may need a splash of milk to keep the mixture smooth.
- Use your favorite berries: Raspberries, strawberries, blueberries, or mixed berries all work beautifully in this recipe.
- Add the peanuts just before serving: This helps keep them crunchy and prevents them from softening in the fridge.
- Perfect for meal prep: Double or triple the recipe and store individual portions in the fridge for easy breakfasts throughout the week.
- Make it your own: Try adding chia seeds, extra peanut butter, fresh berries, or a drizzle of honey on top before serving for even more flavor and texture.
