❓FAQS
You can add protein powder to the Greek yogurt layer if you want to increase the protein content.
Because different protein powders absorb different amounts of liquid, you may need to add a splash of milk to keep the yogurt layer creamy.
Absolutely. If you want a larger serving or a thicker Weetbix base, use 2 Weetbix and increase the milk accordingly.
For the best texture and freshness, I recommend enjoying this overnight Weetbix within a couple of days when stored covered in the refrigerator.

Notes
Use thick Greek yogurt.
Thick Greek yogurt gives the yogurt layer a creamy texture and helps the overnight Weetabix hold its layers.
Adjust the milk if needed.
Different brands of Weetabix can absorb liquid slightly differently. If your base looks dry, add another teaspoon or two of milk.
Thin the peanut butter topping.
If your peanut butter is difficult to spread, mix it with the milk and cocoa powder until smooth. Add a little extra milk if necessary.
Let it sit overnight.
While you can enjoy overnight Weetabix after a few hours, leaving it overnight gives the Weetbix plenty of time to soften.
Use a jar or glass container.
A small jar or glass makes it easy to layer the ingredients and store your breakfast in the fridge.
