In a bowl, add dark chocolate and butter and melt it over a double boiler or in the microwave till it’s smooth.
Add warm milk to the chocolate mix and whisk until well combined.
Add sugar, flour, cocoa powder, coffee and whisk again to make a smooth batter.
Pour the batter into a microwave safe dish (3.5X6 inches) and microwave on regular heating mode for 90 seconds. This is the mode you use to re-heat your food, by pressing a quick start button.
Place the Magnum on top of the lava pudding and dig in!
