How to make my Nutella Weetbix slice recipe

1. Preheat and prep your tin

Preheat your oven to 180ºC (or 160ºC fan-forced).
Line a slice pan with baking paper, making sure the edges hang over for easy removal later.

2. Mix the dry ingredients

In a large mixing bowl, combine:

Crushed Weetbix
Desiccated coconut
Self-raising flour
Brown sugar

Stir until everything is evenly mixed.

3. Add the wet ingredients

Add in the Nutella, melted butter, vanilla extract, and egg.
Mix well until everything comes together and forms a thick, slightly sticky mixture.

4. Press and bake

Spoon the mixture into your prepared pan.
Press down firmly using the back of a spoon or spatula to create an even base.
Bake for 15 minutes, or until the slice is golden brown and just set in the centre.

5. Cool and drizzle

Allow the slice to cool completely in the pan.
Drizzle with melted white chocolate using a spoon or piping bag for extra flair.

6. Slice and serve

Once the chocolate has set, cut into squares or bars.
Store in an airtight container — if they last that long!
