Cake in a Giant Container

Start by pouring the chocolate milk over a chocolate cake in a large container. 

Next, using a thick straw, poke holes all over the cake. 

Place it in the refrigerator and let it chill for 15 minutes.

In a large bowl, add the well-chilled whipping cream mixture, the chocolate mousse mix and beat everything very well until it reaches stiff peaks.

Add this mixture to the container with the cake and with the help of a spoon, spread everything evenly.

Then, to decorate, add the ripe strawberries cut in half and the fresh blueberries alternately along the edges. 

Add the white chocolate bar in the center, then add the milk chocolate bars and the dark chocolate bars. 

Then add the Ferrero Rocher chocolates between the chocolate bars. 

Finish by sprinkling ground pistachios on top.

Place the dessert in the refrigerator and let it chill for at least 3 hours.

Serve.
