Rich Chocolate and Chocolate Pudding Cake

¾ cup flour
2 tsp baking powder
pinch of salt
¼ cup butter
1 ounce unsweetened chocolate, chopped into small pieces
1 cup sugar
5 tbs milk
¼ tsp vanilla
heavy cream, for serving

For the Topping
2 tbs unsweetened cocoa powder
½ pint hot water
7 tbs dark brown sugar
5 tbs sugar
2 tbs unsweetened cocoa powder

1. Preheat oven to 350 degrees. Grease a 9 inch square non stick baking pan.
2. Sift the flour, baking powder and salt into a small bowl. Set aside.
3. Melt the butter, chocolate and sugar in a heatproof bowl set over a saucepan of simmering water, or in a double boiler, stirring occasionally. Remove the bowl from the heat.
4. Add the flour mixture and stir well. Stir in the milk and vanilla extract. Mix with a wooden spoon, then pour the mixture into a prepared baking pan.
5. To make the topping, dissolve the cocoa powder in the water in a bowl. Let cool.
6. Mix the brown sugar, sugar and cocoa powder in a bowl. Sprinkle the mixture over the pudding mixture.
7. Pour the water and cocoa powder mixture evenly over the surface. Bake for 40 minutes or until the pudding had puffed up and set on top. The water mixture will have formed a creamy sauce underneath. Serve immediately with whipped cream.
