Rhubarb Pudding

Preheat the oven to 375 degrees F. Grease a 9x13 baking dish.

Sift together the flour, baking powder, sugar, and salt and place in a bowl.

Stir the milk and rhubarb into the flour mixture until just combined. Pour the batter into the prepared baking dish.

In a saucepan, bring the water to a boil over medium-high heat. Remove from the heat. Stir in the brown sugar, butter, and vanilla and mix until the sugar dissolves. Gently pour the sauce over the rhubarb batter in the baking dish.

Cover the baking dish with foil and place in the oven. Bake at 375 degrees F for 40 minutes or until the pudding is set. Remove from the oven. Serve warm or chilled.
