  1. Preheat the oven to 350°F. Line a baking pan with aluminum foil and leave a 2-inch overhang on short sides. Then, coat the surface with baking spray.
  2. Melt the chocolate and butter together in the microwave, stirring occasionally. Add the cocoa, canola oil, and vanilla and combine well.
  3. Add sugar and brown sugar to the chocolate mixture and whisk to combine. Add the eggs, one at a time, and whisk until smooth. Fold in flour, cornstarch, salt, and baking powder gently, and make sure not to overmix the batter. Transfer to the baking pan.
  4. Bake for about 55-60 minutes or until a wooden pick inserted in the center comes out with a few moist crumbs. Leave the pan to cool down on a wire rack for about an hour. Then, cover and place in refrigerator for one more hour.
  5. Now it’s time to make the ganache. Put the chocolate in a mixing bowl and set aside. Let the heavy cream simmer over medium-high while stirring from time to time. Pour it over the chocolate and mix until fully melted. Then, add butter and salt and combine until you get a smooth texture.
  6. Place the brownie on a cutting board and remove the aluminum foil. Trim the outer edges and spread the ganache evenly. Sprinkle some candy-coated chocolates on top and let it chill for about five minutes.
  7. Cut into 12 even pieces and enjoy!
