Preheat the oven to 350F (180C). Grease with butter a 2 quart (2l) casserole dish or simply a 8-9 inch (20-23cm) square pan.
In a bowl sift together flour with sugar, cocoa powder, salt, instant coffee powder and baking powder.
Add milk, melted butter or vegetable oil and vanilla extract. Whisk to combine.
Pour the batter into the prepared baking dish.
In a small bowl whisk together both sugars with cocoa powder. Sprinkle mixture on top of the batter.
Pour the hot water on top and do not stir.
Bake for 25-30 minutes until the top is set.
Let it cool for 15 mins before serving.
Spoon on serving dishes, drizzle with pudding sauce from the bottom of the pan, serve with ice cream and fresh raspberries. Enjoy!
