Peanut butter Weet-Bix™ slice

Serves: 18
Prep: 10
Cook: 15

    If you love peanut butter as much as we do, this peanut-butter-packed slice is the perfect sweet indulgence.


    • 5 Weet-Bix, crushed (85g)
    • 1 cup white self-raising flour (140g)
    • 1/2 cup desiccated coconut (35g)
    • 1/4 tsp salt
    • 150 g margarine, melted
    • 1 cup caster sugar (200g)
    • 1/3 cup Sanitarium Natural Peanut Butter (90g)
    • 1/4 cup Sanitarium Natural Peanut Butter (70g)
    • 1/4 cup icing sugar (35g)
    • 1 Tbs margarine, melted (20g)
    • 1 Tbs boiling water


    1. Preheat oven to 180°C. Line base and sides of a 20cm x 30cm slice tin with baking paper.
    2. In a large bowl, stir together Weet-Bix, flour, coconut, and salt.
    3. Combine melted margarine, sugar, and peanut butter in a in a pan or heat-proof jug and mix until smooth. Add wet ingredients to dry and stir well.
    4. Immediately transfer base mixture into the prepared tin and smooth surface.
    5. Bake 15 minutes until golden – slice is soft when hot and will firm up as it cools. Cool in tin 20 mins, then transfer to a rack to cool completely.
    6. To make icing, combine peanut butter, icing sugar, margarine and hot water in a small bowl. Stir until thick and smooth – it may look split at first, but just keep stirring and it will come together. Spread icing over cooled slice. Cut into 18 pieces.


    • Icing will set to the touch at room temperature. Store extra slice in a sealed container in the fridge.
    • Both smooth and crunchy peanut butter will work in this recipe.
