Biscuit Layer
- ¼ cup milk
- 175 g digestive biscuits (about 22–24 biscuits)

Instructions
Prepare the Vanilla Custard
- In a medium saucepan, whisk together the granulated sugar and cornstarch.
- In a separate bowl, whisk the egg yolks with the milk until smooth.
- Slowly pour the milk mixture into the saucepan in several additions, whisking well after each addition.
- Place the saucepan over medium-low heat and cook, whisking constantly, until the custard thickens and begins to boil, about 6–8 minutes.
- Remove from the heat and stir in the butter and vanilla extract until completely melted and smooth.
- Transfer the custard to a heatproof bowl and cover the surface directly with plastic wrap to prevent a skin from forming.
- Cool completely to room temperature.
- Fold in the whipped topping, if using, then refrigerate until ready to assemble.
Assemble the Cake

- Quickly dip each digestive biscuit into the milk for about 1 second per side.
- Arrange one layer of soaked biscuits in a 9×9-inch square baking dish.
- Spread half of the chilled vanilla custard evenly over the biscuits.
- Repeat with another layer of dipped biscuits and the remaining custard.
- Finish with a final layer of dipped biscuits.
- Cover and refrigerate for at least 4 hours to allow the Vanilla No Bake Biscuit Cake to firm up.
Prepare the Chocolate Topping
- Combine the chopped chocolate and milk in a heatproof bowl.
- Melt over a double boiler or microwave in 30-second intervals, stirring until smooth.
- Pour the chocolate mixture over the chilled biscuit cake.
- Spread evenly with a spatula.
- Refrigerate for another 20–30 minutes until the chocolate is fully set.
- Slice into squares and serve chilled.
