📋 Ingredient Notes & Substitutions

Ingredients needed to make Weetbix slice is Weetbix, water, chia seeds, almond butter, honey, white chocolate chips and coconut oil.
  • Chia seeds – do not substitute these for another seed.
  • Weet-bix – is also known as Weetabix in the UK. To make gluten-free, use gluten-free Weet-bix. For a US substitute, try using Shredded Wheat or Unsweetened Weeties.
  • Almond butter – can try substituting with another nut butter such as peanut or cashew butter.
  • Honey – use runny honey, not solid or emulsified raw honey. I have not tested this recipe using maple syrup. The sticky consistency of honey helps to stick the base together.
  • White chocolate chips – you may substitute this with dark or milk chocolate chips using the same quantity.
  • Coconut oil – is used to thin out the consistency of the white chocolate chips. You can try substituting it with another neutral-flavored vegetable oil.

💭 Expert Tips

  • Mix the Weetbix mixture with your hands: instead of a wooden spoon, it’s easier to mix the base with your hands since the almond butter is quite thick.
  • Firmly press the Weetbix base into the tin: make sure to pack the base mixture in firmly to ensure a solid and sturdy slice.
  • Use good-quality white chocolate chips: for the topping to ensure a smooth and creamy consistency.
  • If the white chocolate is too thick: add more coconut oil to thin it out until you can spread it.
  • Refrigerate the slice: long enough so the base becomes firm and it’s easy to cut into squares.
  • Slice it with a warm knife: Hold your knife under hot running water from the tap for a few seconds, wipe it dry then cut your slice. A warm knife is easier to cut through solid chocolate on top.

    This is one of my sons favourites. We make it together & he eats so much of the mixture before I can even get it into the pan to set!

    Such a good way to use up weetbix and I love that it is no bake. My son has a dairy allergy so I haven’t got to try the white choc icing yet (I do a basic icing sugar / cocoa powder blend for the top with a sprinkle of desiccated coconut.

    Thank you for such a yummy treat. I should also mention we freeze this & it works great.

    1. Hi Cassie, i’m so happy to hear you and your son are enjoying this slice! It’s a fantastic way to use weetbix and the extra crumbs that are always left over. Your cocoa powder icing sounds absolutely delicious, a wonderful alternative to the white choc icing. I’ll have to try it with the cocoa and coconut the next time i make it. You’re so welcome! Glad to hear it has frozen well for you too. Thanks for sharing! Sam 🙂
