This pudding is delicious and easy to prepare. The soft butter cake cooked in the same mold as the caramel sauce.

Put the grill at the center of the oven. Preheat the oven to 350 ° F. Butter a 9-inch x 6-inch x 3-inch baking pan with a capacity of approximately 6 cups.
Put the brown sugar, butter and water in a medium pot. Over medium heat, bring to a boil, stirring constantly with a wooden spoon. Boil for 1 minute, remove from heat and set aside.
In a medium bowl or the stand mixer bowl, beat the butter and sugar until smooth. Add the egg and beat until the mixture turns pale and homogeneous
In a second bowl, combine the flour, baking powder and salt and stir into the first mixture, alternating with milk and vanilla. Scrape the bowl once or twice during this step and beat until smooth not more. Pour the dough in the mold and pour the sauce over the dough without mixing it (when baking, the cake will float on the sauce).
Bake for 30 Minutes until a toothpick inserted in the center of the pudding comes out clean.
