Ingredients

Chocolate Weet-Bix Slice

4 Weet-Bix
1 cup self-raising flour
1 cup coconut
½ cup caster sugar
1 tablespoon cocoa
250g butter
1 teaspoon vanilla
1 teaspoon peppermint essence

Peppermint Icing

2 cups icing mixture
¼ cup cocoa
30g butter, melted
Boiling hot water
1 teaspoon peppermint essence
A few drops of green food colouring

Instructions

Preheat your oven to 160ºC fan-forced. Line a slice tray with baking paper.
In a large bowl, crush the Weet-Bix with your hands, then add the flour, coconut, caster sugar, and cocoa. Stir to combine.
Melt the butter, then add it to the dry ingredients along with the vanilla and peppermint essence. Mix well until all ingredients are evenly combined.
Press the mixture firmly into the lined slice tray, using the back of a spoon or the base of a glass to create a smooth, even surface.
Bake for 20-25 minutes, or until the slice feels firm to the touch. Set aside to cool completely before icing.

Peppermint Icing

Sift the icing mixture into a bowl.
Add the melted butter and stir to combine.
Gradually add boiling water, a little at a time, stirring until you reach a smooth, spreadable consistency. Be careful not to make it too runny.
Mix in the peppermint essence and add green food colouring, one drop at a time, until you reach your desired shade.
Spread the icing evenly over the cooled slice. Leave plain or decorate with sprinkles, coconut, or your favourite topping.
Allow the icing to set in the fridge before slicing into squares. Enjoy!

Notes

If your icing is too runny, stir in a little extra sifted icing sugar until it thickens to a smooth, spreadable consistency.
You can ice the slice while it’s still warm, or wait until it has completely cooled before adding the icing—both work well!
For cleaner slices, place the iced slice in the fridge for a few hours before cutting. This helps the icing set and makes slicing easier.
