Ingredients
-
- For the brownies:
- 10 tablespoons (142 grams) unsalted butter
- 1 cup (200 grams) granulated sugar
- 1/3 cup (67 grams) packed light brown sugar
- 3/4 cup plus 2 tablespoons (88 grams) unsweetened cocoa powder, sifted
- 1/2 teaspoon vanilla extract
- 2 large eggs plus 1 egg yolk
- 1 tablespoon corn syrup
- 2/3 cup (85 grams) all-purpose flour
- 1 tablespoon cornstarch
- 1/4 teaspoon fine sea salt
- For the frosting:
- 1/2 cup heavy cream
- 1 1/2 cups (255 grams) semisweet chocolate chips
- Rainbow candy-coated chocolate chips, mini M&M’s, or sprinkles (for topping)
Instructions
- Preheat oven to 350°F (175°C). Line an 8×8-inch metal baking pan with parchment paper or foil and spray with nonstick cooking spray.
- In a large microwave-safe bowl, melt the butter (about 90 seconds on high). Stir in granulated sugar, brown sugar, and sifted cocoa powder. Let cool slightly if hot.
- Add vanilla extract, eggs, egg yolk, and corn syrup. Stir until very well combined.
- Add flour, cornstarch, and salt. Stir until just combined. Batter will be thick.
- Pour batter into the prepared pan and smooth into an even layer. Bake for 25 minutes. Let cool completely in the pan on a wire rack.
- For the frosting, microwave heavy cream in a bowl for 1 minute. Add chocolate chips and let sit for 3 minutes, then stir until smooth.
- Pour frosting over cooled brownies and spread evenly. Top with rainbow candy-coated chocolate chips or sprinkles.
- Refrigerate for 1 to 2 hours, or until frosting is set. Cut into 16 squares and serve chilled.
Notes
- Use a metal baking pan for the best texture and even baking.
- Do not overbake—brownies should be set but soft for a chewy texture.
- Store in an airtight container at room temperature for 3 days or in the fridge for up to 1 week.
- For cleaner slices, chill the brownies fully and use a sharp knife wiped clean between cuts.
