Ingredients
For the Brownies:
- 1 cup unsalted butter melted and slightly cooled (2 sticks, 230 grams)
- 1 ¾ cups granulated sugar (350 grams)
- ½ cup packed light brown sugar (100 grams)
- 3 large eggs at room temperature
- 1 large egg yolk at room temperature
- 1 teaspoon pure vanilla extract
- 1 cup unsweetened cocoa powder (90 grams)
- 1 cup all-purpose flour spooned & leveled (125 grams)
- ½ teaspoon salt
For the Ganache:
- 8 ounces semisweet chocolate finely chopped (226 grams)
- 1 tablespoon light corn syrup optional but adds glossiness (20 grams)
- ½ cup heavy cream (120 ml)
For the topping:
- Rainbow candy coated chocolate chips, mini m&m's, or sprinkles
Instructions
- To make the brownies: Preheat the oven to 350°F (180°C). Line a 9x13-inch baking pan with foil or parchment paper, making sure to leave some overhang for easy removal. If using foil, spray it well with nonstick cooking spray, and set aside.
- In a large mixing bowl, whisk together the melted butter, granulated sugar, and brown sugar until well combined. Then whisk in the eggs, egg yolk, and vanilla extract until fully combined.
- Sift in the cocoa powder, flour, and salt and continue whisking until just combined, stopping to scrape down the sides of the bowl as needed.
- Scoop the batter into the prepared baking pan and spread it around into one even layer. Bake for 27 to 33 minutes or until a toothpick inserted into the center comes out clean with just a few moist crumbs.
- Remove from the oven and allow to cool completely.
- To make the ganache: Place the chopped chocolate and corn syrup into a large heatproof bowl. Set aside.
- Heat the heavy cream in a medium pot and bring to a simmer on the stove (or heat in the microwave for 45 seconds to 1 minute).
- Pour the simmering cream over the chocolate and let it sit for 3 minutes.
- Mix with a rubber spatula or spoon until the mixture is smooth and well combined. If any chocolate clumps remain, microwave in 20 to 30-second increments until melted and smooth.
- Use a spatula or spoon to spread the chocolate ganache over the cooled brownies.
- Sprinkle with rainbow candy coated chocolate chips, mini M&Ms, or sprinkles. Refrigerate for 1 to 2 hours to allow the ganache to set before serving. Cut into squares when ready to serve!
