Ingredient Notes
Weet-Bix
The crushed Weet-Bix gives the slice its unique texture and delicious malty flavour that Australians know and love.
Fresh lemon
Using both the zest and juice gives the slice a lovely natural lemon flavour without being overpowering.
Desiccated coconut
Adds texture throughout the slice while also making a beautiful topping mixed with fresh lemon zest.
Butter
Melted butter binds everything together and creates the rich, buttery base.
Storage
Store the slice in an airtight container in the refrigerator for up to 5 days.
It also freezes beautifully for up to 3 months. Simply thaw overnight in the refrigerator before serving.
Variations
Add a little extra lemon zest or juice if you enjoy a stronger citrus flavour.
Sprinkle toasted coconut over the icing instead of regular coconut.
Frequently Asked Questions
Can I freeze Lemon Weet-Bix Slice?
Yes. Store individual pieces in an airtight container and freeze for up to 3 months.
Can I use bottled lemon juice?
Fresh lemon juice is recommended as it gives a much brighter, fresher flavour.
Can I make this ahead of time?
Yes! This is a great make-ahead slice and actually tastes even better the next day. Prepare it up to 3 days before serving and keep it refrigerated in an airtight container.
Why is my icing too runny?
If your icing is too thin, simply add a little extra icing sugar, a tablespoon at a time, until it reaches a thick, spreadable consistency.

Lemon Weet-Bix Slice
Ingredients
- 4 Weet-Bix, crushed
- 1 cup self-raising flour
- 1 cup coconut
- Zest of 1 lemon
- ½ cup caster sugar
- 250g butter, melted
- 1 teaspoon vanilla
- 3 cups icing mixture
- Juice ½ lemon
- 30g unsalted butter, softenend
- 2-3 tablespoons milk
- 2 tablespoons desiccated coconut
- Rind of 1 lemon
Instructions
- Preheat the oven 160’C. Line a slice tray with baking paper.
- Measure all the dry ingredients including the lemon zest into a bowl and stir.
- Add melted butter and vanilla to the dry ingredients and stir until all ingredients are well combined.
- Pour the mixture into the lined slice tray and spread out. Flatten with the back of a spoon or the base of a glass to ensure the slice has a smooth top.
- Bake in the oven for 20-30 minutes. Prepare the icing while the slice is baking.
- Sift icing mixture into a large bowl.
- Add butter and lemon juice and stir.
- Slowly add milk, 1 tablespoon at a time, and stir until desired thickness is achieved. Your icing should have a thick smooth consistency without being runny.
- Spread over the cooled slice.
- In a small bowl, mix together the coconut and lemon rind. Sprinkle over the icing and allow to set.
- Use a sharp knife to cut the slice into serving pieces. I find chilling the slice in the fridge helps.
