Combine the sugar, maizena and cocoa. Add a little milk and stir it to a thin paste.

Bring the rest of the milk to boil. Remove the pan from the heat and mix in the maizena paste. Cook for 2 minutes while whisking. Pour the mixture in a bowl and cover with foil. Let it cool down.

Distribute half of the chocolate pudding over 4 bowls. Cut the bananas in slices and lay half of the slices on the pudding. Pour the rest of the pudding in the bowls and place the remaining banana slices on top.

Let it cool down completely in the fridge, and enjoy your dessert!
