Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Brownie mix provides the perfect foundation for this layered dessert. Using a boxed mix saves time without sacrificing flavor, and the dense texture creates an ideal base for the mousse layer.
Egg acts as a binding agent in the brownie layer, helping to create that perfect fudgy texture that contrasts beautifully with the mousse.
Unsalted butter adds richness to both the brownie base and the French silk layer. Using unsalted allows you to control the overall saltiness of the dessert.
Milk helps to thin the brownie batter slightly, creating a more tender crumb than if you were to follow the box directions.
Cream cheese forms the foundation of the French silk layer, providing tanginess that balances the sweetness and adds a velvety mouthfeel.
Vanilla extract enhances the flavor profile of the French silk layer with its warm, aromatic notes that complement the chocolate perfectly.
Powdered sugar incorporates smoothly into the French silk mixture without the graininess that granulated sugar might leave behind.
Semi-sweet chocolate brings the signature chocolate flavor to the French silk layer. Its balanced sweetness allows the chocolate flavor to shine without becoming cloying.
Cool Whip lightens the French silk mixture and creates the airy, mousse-like texture that makes this dessert so special. It’s also used as the final topping layer.
Chocolate shavings or mini chocolate chips add a decorative touch and hint at the chocolate goodness inside. They also provide a slight textural contrast to the smooth topping.

Directions

Preheat oven to 350°F. Grease an 11×7-inch glass baking dish with non-stick spray.
In a bowl, combine brownie mix, egg, melted butter, and milk. Stir until smooth. Spread batter in the dish and bake 25-28 minutes or until a toothpick comes out clean. Cool completely.
Beat cream cheese and vanilla until smooth. Add powdered sugar and mix until combined.
Melt semi-sweet chocolate and butter in 30-second intervals, stirring between each until smooth.
Add melted chocolate mixture to cream cheese mixture; stir to combine. Fold in 8 ounces Cool Whip gently.
Spread French silk layer over cooled brownies. Spread remaining Cool Whip on top.
Sprinkle with chocolate shavings or mini chocolate chips if desired. Slice and serve.

These brownies are meant to be enjoyed cold and do not require reheating.

FAQs

Can I use homemade brownies instead of a box mix?

Yes, you can absolutely substitute your favorite homemade brownie recipe. Just make sure to bake them in the same size pan for similar results, and allow them to cool completely before adding the French silk layer.

Why do my brownies need to cool completely before adding the French silk layer?

Adding the French silk layer to warm brownies would cause the chocolate and whipped topping to melt, resulting in a runny mess rather than distinct layers. Patience yields the best texture and presentation.

Can I use regular whipped cream instead of Cool Whip?

Yes, you can substitute homemade whipped cream. Whip 2 cups of heavy cream with 1/4 cup powdered sugar and 1 teaspoon vanilla until stiff peaks form. However, note that homemade whipped cream may deflate more quickly than Cool Whip.

My French silk layer is too runny. What went wrong?

This typically happens if the cream cheese was too warm or if the chocolate mixture was still hot when combined. Make sure your cream cheese is room temperature (but not overly soft) and let the melted chocolate cool slightly before mixing.

Can I make these brownies gluten-free?

Yes, simply use a gluten-free brownie mix and verify that all other ingredients are gluten-free. The French silk and topping layers are naturally gluten-free.

How far in advance can I make this dessert?

These brownies can be made up to 2 days in advance and stored in the refrigerator. They actually benefit from some refrigeration time as the flavors meld together.

Can I use dark chocolate instead of semi-sweet?

Absolutely! Dark chocolate will create a less sweet, more intense chocolate flavor. You may want to adjust the powdered sugar to taste if using a higher percentage cacao chocolate.

My brownie layer is too dry. How can I prevent this?

Avoid overbaking the brownies. They should be just set when a toothpick comes out with a few moist crumbs. The milk and butter in this recipe help create a more moist brownie than traditional box mix directions.

Can I add nuts to this recipe?

Yes, chopped walnuts or pecans would make a delicious addition to the brownie layer. Simply fold 1/2 cup of chopped nuts into the brownie batter before baking.

Do I need to refrigerate these brownies before serving?

Yes, refrigeration for at least 2-3 hours is recommended to allow the French silk layer to set properly and for the flavors to develop fully. This also makes the brownies easier to cut cleanly.

French Silk Brownies represent the perfect marriage of convenience and indulgence.
