Chocolate Brownies with Peanut Butter Mousse

Ingredients

1 ½ cups all-purpose flour: For structure; use whole wheat flour for a nuttier flavor.
1 tablespoon cornstarch: Helps to keep the brownies chewy.
⅓ cup Dutch-processed cocoa powder: This gives deep chocolate flavor; I recommend Dutch-processed for its smoothness.
½ teaspoon baking powder: For leavening.
¼ teaspoon kosher salt: Enhances the flavors.
4 large eggs, room temperature: Ensures a smoother batter.
2 cups granulated sugar: Sweetens and gives the brownies their delicious texture.
¾ cup unsalted butter, room temperature: Use good quality butter for the best flavor.
2 teaspoons vanilla extract: Adds warmth to the flavor.
1 recipe peanut butter mousse, prepared: A necessary indulgent layer!
Chopped peanuts, for garnish: Adds a crunchy finish.
Chocolate syrup, for garnish: Drizzle for elegance.
Peanut butter, melted for garnish: Elevate the decadence!

Prep Notes: Remember to bring your eggs and butter to room temperature for a smooth mix!

Step-by-Step Instructions

Step 1: Preheat, Prep, and Whisk

Preheat the oven to 350°F (175°C). Line a 9×13-inch baking dish with parchment paper, leaving some overhang for easy removal.
In a large bowl, whisk together the flour, cornstarch, cocoa powder, baking powder, and salt. Set aside.

Step 2: Mix the Brownie Batter

In a stand mixer fitted with the paddle attachment, add eggs, sugar, butter, and vanilla. Beat on medium speed for about 3-4 minutes, or until light and fluffy.
With the mixer off, add the flour mixture. Turn the mixer on low to combine until everything is incorporated, being careful not to overmix.

Step 3: Bake

Pour the brownie batter into the prepared baking dish and use a spatula to spread it evenly.
Bake for 30-35 minutes. The brownies are done when the edges look set, and the center is still shiny and slightly moist. Keep an eye on them to avoid overbaking!

Step 4: Cool and Top

Once baked, let the brownies cool at room temperature for about 20 minutes.
Spoon the peanut butter mousse over the cooled brownies, spreading it into an even layer.
Garnish with chocolate syrup, chopped peanuts, and melted peanut butter for that extra flair!

Chef’s Tips:

Use a toothpick test to check for doneness—if it comes out with a few moist crumbs, you’re good to go.
If you like your brownies extra fudgy, err on the side of underbaking by a minute or two.

Expert Tips & Tricks

Storage Recommendations: Store the brownies in an airtight container at room temperature for up to 3 days or in the fridge for up to a week. They can also be frozen for up to 3 months—just thaw before serving.
Make Ahead Instructions: Brownies can be made and stored for a couple of days in advance. You can also prepare the peanut butter mousse ahead of time, just be sure to re-whip before spreading it on the brownies.
Troubleshooting Common Problems:
- If your brownies come out too dry, try reducing the baking time next time or adding more butter.
- For an overly gooey center, even after cooling, ensure to check the center is set during baking.
Using Quality Ingredients: I always recommend using high-quality cocoa powder and chocolate when making brownies—the better the ingredient, the better the taste!
Mix-ins are Key: Feel free to experiment with different mix-ins or flavorings (like espresso powder for a mocha kick!).
