ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

For the brownie base:

• 1 box brownie mix
• Ingredients as listed on the brownie mix package (typically oil, eggs, water)

For the French silk layer:

• 3/4 cup butter, softened
• 1/2 cup sugar
• 4 tablespoons cocoa powder
• 3 large eggs

For the whipped topping:

• 1 container (8 oz) whipped topping (such as Cool Whip), thawed
• Chocolate shavings or curls, for garnish (optional)

directions

1. Bake the brownies:
   Preheat the oven to 350°F (or according to the package instructions). Prepare and bake the brownies in a 9×13-inch pan as directed on the box. Allow to cool completely before adding the next layer.
2. Prepare the French silk layer:
   In a large mixing bowl, beat softened butter and sugar until light and fluffy.
   Add cocoa powder and mix until fully incorporated.
   Add eggs one at a time, beating each on high speed for 3 full minutes before adding the next. This step is key to achieving a creamy, mousse-like texture.
3. Layer the brownies:
   Once the brownies are cool, spread the French silk mixture evenly over the top.
4. Add the whipped topping:
   Gently spread the whipped topping over the French silk layer until smooth.
5. Garnish and chill:
   Sprinkle with chocolate shavings or curls if desired.
   Refrigerate for at least 2–3 hours, or until fully set. Slice into 12 squares and serve chilled.

FAQs

Can I make this ahead of time?

Yes, these brownies are ideal for making ahead. Chill overnight for best results.

Can I use homemade whipped cream?

Absolutely. Whipped heavy cream with a bit of powdered sugar works well. Just be sure it’s stabilized if you’re making the dessert in advance.

Is it safe to use raw eggs?

Because the eggs in the French silk layer are not cooked, it’s recommended to use pasteurized eggs to reduce any food safety risks.

Can I make this gluten-free?

Yes, just use a gluten-free brownie mix and verify that your other ingredients are gluten-free.

How do I get clean slices?

Chill well before slicing, and wipe your knife clean between cuts for neat squares.

Can I use dark chocolate cocoa powder?

Yes, using dark cocoa will give the silk layer a richer, more intense chocolate flavor.

What if I don’t have whipped topping?

You can whip 1 cup of heavy cream with 2 tablespoons powdered sugar and 1/2 teaspoon vanilla until stiff peaks form.

Can I use a stand mixer?

Yes, especially for the French silk layer—beating each egg for a full 3 minutes is key to the texture.

What’s the texture of the French silk layer?

It’s light, airy, and creamy—like a chocolate mousse.

Are these brownies best served cold?

Yes, chilling enhances both flavor and texture. Serve directly from the refrigerator.
