# Ingredients List:

→ Dry Ingredients

01 - 190 grams all-purpose flour
02 - 8 grams cornstarch
03 - 28 grams Dutch-processed cocoa powder
04 - 2 grams baking powder
05 - 1 gram kosher salt

→ Wet Ingredients

06 - 4 large eggs, room temperature
07 - 400 grams granulated sugar
08 - 170 grams unsalted butter
09 - 10 milliliters vanilla extract

→ Mousse Topping

10 - 360 milliliters heavy whipping cream, cold and divided
11 - 170 grams semi-sweet chocolate chips

→ Garnish

12 - Chocolate curls (optional)

# Detailed Cooking Steps:

01 - Preheat the oven to 175°C. Line a 23x33 cm baking dish with parchment paper, leaving an overhang for easy removal.
02 - In a bowl, sift together the flour, cornstarch, cocoa powder, baking powder, and salt until thoroughly combined.
03 - In a separate large bowl, beat the eggs and sugar until pale and thick. Melt the unsalted butter and incorporate it along with the vanilla extract into the egg mixture.
04 - Gradually fold the dry ingredient mixture into the wet ingredients until just combined, avoiding overmixing to retain a tender texture.
05 - Pour the batter into the prepared baking dish and smooth the surface. Bake for 28 to 30 minutes or until a toothpick inserted comes out with moist crumbs. Remove from oven and allow to cool.
06 - Heat 120 milliliters of the cold heavy cream in a saucepan until warm but not boiling. Remove from heat and stir in chocolate chips until fully melted and smooth. Allow to cool to room temperature.
07 - Whip the remaining 240 milliliters of cold heavy cream until stiff peaks form. Gently fold the whipped cream into the cooled chocolate mixture to create a light mousse.
08 - Spread the chocolate mousse evenly over the cooled brownie base and refrigerate for at least 2 hours to set.
09 - Before serving, optionally garnish with chocolate curls for added texture and presentation.

# Helpful Hints:

01 - For enhanced richness, substitute semi-sweet chocolate chips with dark chocolate. Use very cold heavy cream to achieve optimal mousse texture. Baking time may vary depending on the oven; look for moist crumbs on a toothpick test as a doneness indicator.
