Preheat oven to 350 and line a 9x13 inch pan with parchment paper.

Melt chocolate and butter in a bowl over a pot of simmering water. Set aside and allow to cool.

Meanwhile, in a small bowl, whisk together applesauce, eggs and vanilla.

In a large bowl, whisk sugar, flour, cocoa powder and baking powder together. Stir in the liquid ingredients. Finally mix in the cooled, melted chocolate. Pour batter into the lined pan.

Bake in the oven for 25-30 minutes. Lastly, place the brownies for 1-2 minutes under the broiler, or until topping is caramelized.
