Creating French Silk Brownies is a fun and straightforward process. Follow these simple steps to ensure your brownies come out perfectly:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan.
2. Make the Brownie Batter: In a medium saucepan over low heat, melt the butter. Once melted, stir in the sugar until well combined.
3. Add Eggs: Remove the pan from heat. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
4. Combine Dry Ingredients: In a separate bowl, whisk together the cocoa powder, flour, and salt. Gradually mix this into the wet ingredients until just combined.
5. Bake the Brownies: Pour the brownie batter into the prepared baking pan. Bake for 25-30 minutes or until a toothpick inserted in the center comes out with a few moist crumbs. Let cool completely in the pan.
6. Prepare the Mousse Topping: In a medium bowl, whip the heavy cream until soft peaks form. Gradually add powdered sugar, whipping until you reach a stiff peak.
7. Melt Chocolate: In a microwave-safe bowl, melt the chocolate chips in 15-second intervals, stirring between each interval until smooth. Let it cool slightly.
8. Combine: Gently fold the melted chocolate into the whipped cream, being careful not to deflate the mixture.
9. Spread the Topping: Once the brownies are completely cool, spread the chocolate mousse evenly over the brownies.
10. Chill: Refrigerate for at least 1 hour to allow the mousse to set.

Through these steps, you will create a delightful treat that will satisfy any chocolate craving!
