Can I make this recipe ahead of time?

Yes. I often prep the brownies in the morning, then spread the mousse and chill in the afternoon. Make it a day ahead for easier hosting.

Can I use low-fat cream for the mousse?

You can, but the mousse will be lighter and less stable. Full-fat cream gives the best texture and mouthfeel.

How do I fix a mousse that looks grainy?

Often it is from overwhipping the cream or cooling the chocolate too fast. Gently fold in a bit more soft whipped cream to smooth it out.

Is there a gluten-free option?

Yes. Replace the all-purpose flour with a 1:1 gluten-free flour blend designed for baking. Watch for differences in texture.

What is the best way to get clean slices?

Chill the pan well and use a sharp knife dipped in hot water. Wipe and reheat the knife between cuts. These are the questions I get most at the end of the meal when plates are clear and people start planning the next dinner. I answer them the way I like to be answered: simply and with a practical fix.

Instructions

Preheat the oven to 350°F (175°C). Grease a 9×13 inch baking pan.
Melt the butter and sugar together over medium heat. Remove from heat and let cool slightly.
Whisk in the eggs and vanilla until smooth. Stir in the flour, cocoa powder, and salt until just combined.
Pour the brownie batter into the prepared pan and bake for 20-25 minutes, or until a toothpick comes out with a few moist crumbs.
While the brownies are baking, make the mousse by heating the cream until just boiling, then pouring it over the chocolate chips. Stir until smooth and let it cool slightly.
Fold in whipped cream until fully combined.
Once brownies are cooled, spread the mousse over the top and refrigerate for at least 2 hours to set.
Top with chocolate ganache before serving. Cut into squares and enjoy!
