Method
- Line an 8x8 or 9x9 inch pan with parchment paper or lightly greased aluminum foil, allowing some overhang.
- Add about 1-2 cm (1/2 - 1 inch) of water to a medium saucepan over low heat. Place a glass bowl on top.
- In the glass bowl, add the butter, sugar, and cocoa powder. Melt together, stirring until smooth and glossy.
- Once melted, add the egg while whisking constantly until mixture becomes thick and glossy.
- Stir in the graham crumbs, coconut, and chopped walnuts to create the base mixture.
- Press the base mixture into the prepared pan and freeze for 20 minutes.
- Beat softened butter until fluffy, then mix in custard powder and heavy cream.
- Slowly beat in the powdered sugar until the custard mixture is very thick.
- Spread the custard layer over the chilled base layer and refrigerate for at least 15 minutes.
- Melt chocolate in a heatproof bowl in the microwave, stirring until smooth.
- Stir in the oil with the melted chocolate and pour over the custard layer.
- Chill the tray in the fridge for about 30 minutes until the chocolate layer is firm.
- Lightly score lines where you’ll cut the bars before the chocolate hardens completely.
- Once fully firm, let the bars sit at room temperature for 10 minutes and then cut along the scored lines.
- Serve cold from the fridge or at room temperature.
Notes
These bars are best served cold and can be stored in the refrigerator for up to a week. Enjoy the layers and consider adding a touch of sea salt on top for an extra flavor boost.
