For the Ganache Topping

  • 1 1/2 cups Semisweet Chocolate Chips provides richness

Method
 

Step-by-Step Instructions
  1. Preheat your oven to 350°F (175°C). Line an 8x8-inch baking pan with parchment paper and lightly coat with cooking spray.
  2. Melt 10 tablespoons of unsalted butter in a microwave-safe bowl for about 90 seconds. Let cool slightly, then add granulated sugar, light brown sugar, and sifted cocoa powder. Stir until well combined.
  3. Add 2 large eggs, 1 egg yolk, and vanilla extract to the bowl. Incorporate corn syrup and blend until smooth and glossy.
  4. Fold in flour, cornstarch, and fine sea salt gradually. Stir gently until just combined.
  5. Pour the batter into the prepared pan and spread evenly. Bake for approximately 25 minutes, until edges are set and center is slightly soft. Let cool completely in the pan.
  6. Heat heavy cream until just about to boil, then remove from heat and add semisweet chocolate chips. Let sit for a few minutes, then stir until smooth.
  7. Pour the ganache over cooled brownies and spread evenly. Top with rainbow candy-coated chocolate chips or sprinkles.
  8. Refrigerate for 1 to 2 hours to let ganache set. Slice into squares using a hot knife.
