Ingredients:

For the cake:

40 g (⅓ cup) cocoa powder
100 g (7 tbsp) butter
300 ml (1 ¼ cups) milk
350 g (12 oz) biscuits (digestive or tea biscuits), broken into small pieces
40 g (⅓ cup) peanuts, roughly chopped
180 g (6 oz) sweetened condensed milk

For the chocolate glaze:

100 g (3.5 oz) chocolate (dark or milk)
20 g (1 ½ tablespoons) vegetable oil
40 g (⅓ cup) peanuts, roughly chopped

Instructions:

Prepare the cake base:

In a saucepan, combine the cocoa powder, butter, and milk. Cook over medium heat, stirring constantly until the mixture boils. Remove from the heat and let cool to room temperature.
In a large bowl, break the biscuits into small pieces. Add 40g of chopped peanuts and stir.
Pour the cooled cocoa mixture and condensed milk into the bowl. Stir until all the ingredients are well combined.

Assemble the cake:

Line a loaf pan (31×12.5×7 cm) with parchment paper or cling film.
Transfer the mixture into the pan, pressing firmly to remove any air pockets and ensure a smooth surface.
Cover the top and place the pan in the freezer for 2 hours to firm up.

Prepare the chocolate glaze:

Melt the chocolate with the vegetable oil in the microwave or in a bain-marie, stirring until smooth.
Add the remaining 40 g of chopped peanuts.
Finish the cake:

Remove the cake from the freezer and spread the chocolate glaze evenly over the top.
Refrigerate the cake for 2 hours to allow the glaze to harden.

Serve:

Cut the cake and serve cold. Enjoy! 5 serving suggestions:
