Lemon Weetbix Slice

Zesty lemon weetbix slice. A delicious and tart slice recipe, that is a fun twist to a classic treat. Perfect for afternoon tea or for a lunch snack.

This lemon slice is really yummy for a treat for afternoon tea. I based this recipe off my chocolate weetbix slice but halved the quantities. My husband absolutely loved it. He said “it is up in his Top 5 of all slices I make”….that is a pretty big call. As it only uses three weetbix, this is a great recipe to use the last of the weetbix in the bottom of the box. You could reduce the lemon juice in the icing if you would prefer less tangy icing on your slice.

Made the Lemon Weetbix slice for the first time yesterday. It is so simple and easy to make. Very tasty. I will add more lemon zest next time. There was no mention of how much vanilla so i put in a teaspoon. It is very moorish. Love it and will definitely make it again.

Can we use limes instead? My lime tree is laden with limes…

I’ve been making this slice for a while and my husband absolutely loves it. I use brown sugar instead of castor and also add some lemon zest to the icing as well as the base.

If lemons aren’t as plentiful, how much bottled lemon/juice could we use as an alternative..

Reply
Katrina - The Organised Housewife May 25, 2022 - 12:23 PM

I would suggest 1-2 tablespoons of bottled lemon juice in lieu of a lemon. Start with 1 and add to taste as bottled lemon juice can be stronger in flavour.
