Optional Decoration
- 100–140g mini eggs (optional)
- 50g white chocolate, melted
Instructions
- Prepare the tin: Line a 20 x 30 cm tin with baking parchment to prevent the cake from sticking and to make removal easier once set.
- Melt chocolate mixture: In a heatproof bowl set over a pan of simmering water, gently melt together the dark chocolate, diced butter, and golden syrup, stirring occasionally until smooth, glossy, and fully combined.
- Add flavors and mix-ins: Stir in the vanilla extract, then fold through the roughly chopped biscuits, sultanas, and Rice Krispies until everything is evenly coated in the chocolate mixture.
- Set the cake: Transfer the mixture into the prepared tin and flatten it down firmly using the back of a spoon, ensuring an even layer. Press in mini eggs evenly on top if using, for added texture and visual appeal.
- Chill to set: Place the tin in the fridge and leave until the mixture is completely set and firm, usually about 2-3 hours.
- Decorate and serve: Once set, drizzle the melted white chocolate all over the top of the cake. Return it to the fridge to allow the drizzle to firm up before cutting into chunks to serve.

- For a nutty twist, add chopped nuts like hazelnuts or almonds into the mixture.
- Store leftover fridge cake in an airtight container in the fridge for up to one week.
