11. 11
    Spoon the chocolate brownies mixture into the pan and bake for 30 minutes. Start testing with a toothpick 5 minutes before the end of baking time. If the toothpick comes out with small amounts of sticky batter and small crumbles then chocolate brownies are baked. But if the toothpick comes out clean then they are probably over-baked.
