Dark Chocolate Mousse Bars

Many of my friends have seen my baking cupboard. It’s that spot where I keep extracts, baking soda, baking powder, cocoa powder and stacks of Ghirardelli chocolate bars. We go through A LOT of those chocolate bars. Bittersweet chocolate is used less than semisweet around here, but it was the perfect way to obtain a deep, rich chocolate flavor in the mousse.

How to Make Chocolate Mousse Bars

This recipe was a cinch to whip up with a phenomenal payoff. To start, mix, spread and tamp an easy graham cracker crust into the pan. Bake and cool while prepping the filling.

Whip room temperature cream cheese until light, then mix in a cup of melted bittersweet chocolate. Note that for a silky smooth filling the cream cheese must not be cold. 

PRO-Tip: If you forget to set your cream cheese out on the counter 1-2 hours before baking, you can place the brick of cream cheese, still in its foil wrapping, in a bowl of warm (not boiling) water to speed up the process. If you use cold cream cheese, you’ll find specks of white in the mousse.

Next, whip some heavy cream and gently fold it into the chocolate mixture to lighten the mousse. Using a cold bowl helps stablize the whipped cream. Pop your bowl in the freezer 15-30 minutes before whipping. Once the whipped cream and chocolate are combined, spread this mousse layer over the crust.

Finally, melt the remaining baking chips with a bit more cream to make the ganache topping. And last, pop the pan in the fridge to chill, and wait patiently. Yes, I wanted to dive right into this layered chocolate wonder and you will, too.

Chocolate Desserts

The hubby got the first taste and gave this chocolate mousse recipe exuberant praise. And one of our dinner guests last month declared them “better than Reese’s!” It’s hard to beat chocolate desserts!

I was thrilled that these dark chocolate mousse bars can be made with ingredients that are almost always found in my kitchen. And you can bet I’ll be adding a stash of these 60% Cacao Bittersweet Chocolate Baking Chips to my baking supplies. These sinfully rich bars are perfect for your Valentine next month!
