Let’s make it
Preheat oven 1600 C. Line a baking sheet with parchment Paper, leaving edges slightly longer to aid in removing brownies from dish once baked.
Melt condensed milk and butter together in a medium saucepan on medium heat, stirring frequently. Once melted, remove from heat and add vanilla and brown sugar. Stir to incorporate.
Mix in cocoa powder, salt, baking powder, and flour and mix until thoroughly blended. Pour batter into prepared baking dish.
Bake for 30 minutes or until middle is just set and sides are slightly crisped.
Rest in pan for 5 minutes before using wings of parchment paper to pull brownies from baking dish. To serve, cut into squares and enjoy warm. Cool completely before storing in an airtight container.
