Do you have a blog crush? Like a serious food blog crush? I do. In fact, I am crushing on a few food blogs right about now. My very first crush was on Simply Recipes way before I had a food blog. I then started to crush on a million others … I am still crushing on all of them. Especially those that have a lot of brownies in their recipe index.

I fall in love with one or two, or ten blogs at a time. My food blog crush, as of late, is on Une Gamine Dans la Cuisine. I think that means, A Girl in the Kitchen. I think. I took 4 years of French and learned almost nothing. Almost.

Valerie, the author, is way awesome. Way. She can bake, she can write, she can photograph… She’s also funny. In a sarcastic-way-funny. And she’s a NKOTB fan! Need I say more!?

Oh yeah, I do. I was going somewhere with this. She makes brownies!

One day, while I was stalking browsing her blog, I jotted down this brownie recipe, gave it a day, and whipped it up. Um…whoa! It’s fab and fudgy. Only thing I did different was I added some chocolate mousse on top instead of ganache… Nothing against ganache. I love ganache! I just felt like eating Chocolate Mousse Brownies that day. It’s so good!

You should make these brownies ASAP!  You will definitely enjoy them as much as we did. These were polished off in less than a day, and that’s only because none of us wanted to look like a pig in front of one another. Otherwise, these babies would have been gone the moment I put them on the table.

    I am not sure what happened to mine, but the batter was very dry and I had to spread it in the pan w/ a knife. It never smoothed out even when heated.

    I literally just got done making these brownies with the chocolate mousse topping and they are absolute heaven in my mouth!!! For some reason I thought of Christmas when eating these. I can’t wait to make these again for work, family get-togethers, parties, and etc… I’m thinking about whipping up a batch of Mexican hot chocolate and dolloping the mousse on top! Or even adding the Mexican hot chocolate spices to the mousse also. I could do so much with this wonderful recipe! Thanks for sharing with us!

    1. Katerina Petrovska

      YAY! I’m so happy you enjoyed them!! And yes, they DO taste like Christmas!! haha I’ve always thought that!
      Now I’m going to dream about Mexican Hot Chocolate Mousse! Did you see my Mexican Hot Chocolate Fudge?! To.DIE.for. 😀

      Hi Doreen!!

      Yes, you can definitely make it in an 8×8, but start checking it at 20 minutes; insert a toothpick in the center and when it’s clean, it’s done. If not done at 20, then check at 25, then at 30… it should most definitely be done by 30. You wanna watch the edges; when they start to separate from the pan, its done. Let cool for a while before cutting. Hope this helps!

    Really wanted to follow this recipe through and through, but we had a pack of Ghirardelli brownie mix left in the pantry. I never really liked that mix coz it would always come out too sweet, so imagine my delight when I tried the chocolate mousse part of this recipe on these too-sweet brownies and found that it somehow toned them down! 🙂 I just had to taste the brownies with chocolate mousse ASAP (yummy!), but I’m pretty sure they’re much better served chilled. Kudos!

    Oh wow…this looks so gorgeous and fudgy! I’m the huge fun of Chocolate Mousse Brownies, Definitely giving it a shot, looks great! I had featured U in the post of Here Are Seven New Ways To Make Romantic Chocolate Cakes For Fathers on AllFreshRecipes. Looking forward to ur newly recipes!

  5. Jayne

    Mmmm… brownies with mousse. I already have a great go-to brownie recipe. It’s the mousse that I need right now. 😀

  6. mjskit

    It’s interesting because I didn’t know about food blogs until I started one! Now I’m hooked! I stalk lots and lots of blogs, yours being one of them. 🙂 Love these brownies! Ooey gooey ones are the best kind!

  7. Holly

    Wow- what’s not to like! I could have taken any one of the three words in your title and been happy– chocolate–mousse–brownie– but all together they must be fantastic!!

    i took 7 years of French and know nothing, well except maybe 10 words. I absolutely love Valerie’s blog and yours of course and these brownies look heavenly!

  9. Nami | Just One Cookbook

    I enjoyed visiting Valerie’s site and thanks for introducing another great blog! I love all kinds of brownies, but I realized I haven’t tried “mousse” one before! Looks so delicious!
    p.s. Kate, the ziplist plugin is not working and I see the plugin itself on your post (as if I’m editing the plugin in the post).

  10. Valerie

    *blushing* So far you’re my absolute favourite blog stalker! xo Your French is perfect, although, in this instance, scratch out the “girl” bit and replace it with hobgoblin. 😉

    These brownies are gorgeous! I’m jealous of your fancy frosting.

    1. Kate@Diethood

      That frosting is something I make when I want to grab a spoon and stuff my face with creamy chocolaty yumminess. It’s an instant high. 😉

  11. The Mom Chef ~ Taking on Magazines One Recipe at a Time

    Yeah, I have several blog crushes. I’m writing on one of them right now. 😉

    I’m not a big fan of ganache (way too chocolaty for me), but I could handle a brownie topped with mousse. That sounds divine!

  12. Nancy/SpicieFoodie

    I’m convinced and these babies will be what I serve for my next special occasion. Thanks for sharing the recipe and your blog crush. I too have many blog crushes. Such talent out there!

  13. Paula @ Vintage Kitchen

    I love Valerie´s site, she´s so talented. I´m still laughing at your last paragraph! Gorgeous brownies!
