Many of my friends have seen my baking cupboard…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. But I hadn’t baked with Ghirardelli’s 60% Cacao Bittersweet Chocolate Baking Chips till I tested out these scrumptious Dark Chocolate Mousse Bars.

This recipe was a cinch to whip up…with a phenomenal pay off. To start, an easy graham cracker crust was mixed, tamped, baked and then cooled while the filling was prepped. Room temperature cream cheese was whipped and then a cup of  the bittersweet chocolate baking chips was mixed in. Those chocolate babies  melted like a dream. I then whipped up some cream and folded it into the chocolate mixture to lighten the mousse. So far so good. The mousse layer was spread onto the crust and then the remaining baking chips were melted with a bit more cream to make the ganache topping. I popped the pan in the fridge to chill…and immediately began tapping my toes. Yes, I wanted to dive right into this layered chocolate wonder.

The hubby got the first taste and gave them exuberant praise. I think I saw a pout when I sent half the batch home with our oldest…who also declared them sublime. I am happy 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. Now run to the market to stock up on these chocolate chips as these sinfully rich bars are perfect for your Valentine!

  16. Lizzy,
    I love Ghirardellii. These bars are calling my name.

  17. I love that this recipe is simple yet looks like a something I’d buy at the bakery. I have a few essentials in my baking cabinet, but I may just have to try these Ghirardelli baking chips. One of my goals for 2014 is to bake more. I may have to call on you for help. LOL

  20. Simplicity at its finest and best, Liz. These mousse bars look terrific!

  21. Oh my, we’re on the same wavelength for sure. I’ve just finished 2/3 of a chocolate mousse cake (looks more like a cheesecake to me) and fingers crossed I’ll be able to get it out of the tin without it falling to the floor. I licked the bowl and it tasted pretty good. I might prefer one of these nifty bars with Ghiradelli chocolate. I love it and it’s not here.

  22. Dark chocolate and mousse, I’m so on board with these!

  23. Pouting? Next time you’ll have to whip up a double batch. These do look amazing and chocolate with raspberries is wonderful. I’m still super-impressed with your beautiful fresh raspberries – they look better than ours and ours are in season! xx

  24. As a dark chocolate and Ghirardelli fan, I am sooo pleased to have this recipe, Liz. Thank you!

  25. looks delish! perfect for valentine’s day!

  26. Another gorgeous photo Liz! I wish you could hear me each time I pull up one of your delicious recipes (Mmm)! 😉 I must tr y this!

  27. Sublime is the perfect word to describe these dark chocolate mousse bars, Liz! I adore Ghirardelli and dark is my go-to chocolate. I’m putting this on my must-bake list.

  28. Beautiful bars, I especially love the mousse layer!

  29. OOOOO, MYYYyyy,

  30. These look soooo delish. And gorgeous. I love them – and perfect with Valentines around the corner.

  31. I will be running or walking as fast as my arthritic knees will let me. These bars are heavenly!

  32. I buy so much chocolate and still don’t know where it all goes. I never seem to have a stack in my pantry. These bars look amazing. I would be upset too if half were set away although it would probably be for the better.

  33. Sounds too good to last very long around here!
