Flourless Chocolate Hazelnut Cake

Flourless Chocolate Hazlenut Cake from Sugarlaws

Ok, come on.  How are my words ever supposed to compare with that photo?  Just look at that dense, chocolatey inteseness that can only barely be called a “cake.”

Because this is not a light, fluffy cake.  This is a “two bites later it’s too rich for me” cake (if you’re that type, which I am not).  And if you are true chocophile, and you want something seriously decadent, this is your dream cake.

My cake was just barely set when I tried to cut into it, which was a relatively messy endeavor.  If yours isn’t perfectly set, rest assured that it will solidify in the fridge.  Just don’t overbake it — if worst comes to worst, you can spoon it onto some cold vanilla ice cream, and….

Sorry, I lost my train of thought.  Yes, it’s that good.

Flourless Chocolate Hazlenut Cake from Sugarlaws

Flourless Chocolate Hazelnut Cake

1/2 cup plus 1 tbsp raw hazelnuts
7 Tbsp unsalted butter
1/4 cup unsweetened cocoa powder
3.5 ounces dark chocolate (60 or 70% cacoa)
1/2 cup light brown sugar
2/3 cup granulated sugar
2 large eggs
1 tsp vanilla extract


Preheat the oven to 350 degrees.  Butter an 9-inch tart dish or cake pan and line with alumnum foil.

Toast the hazelnuts in the oven or in a nonstick saute pan on medium heat for 5 minutes. Cool for a few minutes, then place the nuts in a food processor and pulse until the nuts become powder, with a flour-like texture.

Break the chocolate into pieces, and microwave it with the buter for 1 minute on high, then let it rest for several minutes. Stir it — if the chocolate is not melted or close, repeat.  Once everything is melted, stir in the cocoa powder.

Mix together the the sugars, eggs, and vanilla in a large bowl until blended. Add the hazelnut powder and chocolate/butter mixture and fold them into the batter.

Pour the batter into the prepared pan and bake for about 25 minutes, or until the cake is barely set, but not wobbly (a toothpick inserted into the cake will come out with wet crumbs). Cool to room temperature on a rack and then store in the fridge until the cake is set.  Bring to room temperature or briefly reheat before serving.

Serves 8-10.

    The nut “flour” cakes are very traditional to our family. Yours looks wonderful 🙂

  • 3 Elle // Jan 6, 2009 at 6:37 pm

    There’s that out of control flourless cake – omg – I can’t resist it and now you’ve gone and added hazelnuts – you’re definitely trying to kill me, right?

  • 6 Patsyk // Jan 6, 2009 at 9:15 pm

    My first thought was that this would be a great Passover dessert!  Yum!  And, I’m a chocoholic so it’s doubtful I’d consider it too rich after 2 bites… it’s no wonder that I need to hit the gym!

  • 7 Erin // Jan 6, 2009 at 9:49 pm

    This looks so decadent!  I’m a true chocoholic and haven’t experienced the “it’s too rich” feeling yet, so I know I’d enjoy this!

  • 8 Kevin // Jan 6, 2009 at 9:55 pm

    That chocolate cake looks good!

  • 9 Rita // Jan 6, 2009 at 11:21 pm

    **By the way, you were quoted in the recent issue of Whole Foods’ coupon booklet!!:


  • 19 Kasey // Jan 8, 2009 at 5:21 pm

    That cake looks amazing–chocolate and hazelnut are my favorite combination! Reminds me of one I’ve made using a recipe from Chocolate & Zucchini, only that was with raspberries. Same to-die-for fudge consistency, though.

  • 20 Lorraine E // Jan 8, 2009 at 8:46 pm

    I agree flourless chocolate cakes are amazing. And for the true chocoholic! None of this “it’s too rich” business hehe

  • 21 sara // Jan 9, 2009 at 10:48 pm

  • 28 REL // Apr 19, 2009 at 2:03 pm

    So of course I find this right after Passover.. ah well, next year =]

  • 29 John // Oct 23, 2011 at 5:47 pm

    If I used 5″ mini springform pans for “individual” cakes, how should I adjust the cooking time to compensate for the smallel pans?  How many “cakes” would you estimate this receipe to make?  I would like to do these cakes for our monthy neighborhood dinner.  (dessert is at my house)

  • 30 katy // Oct 24, 2011 at 8:10 pm

    My guess would be four individual cakes, but I’ve never tried it!  Any readers who’ve tried the recipe want to chime in and help out?

    is there a way i can modify this recipe for hazelnut spread instead of using raw hazelnuts and chocolate?

  • 33 katy // Feb 15, 2013 at 8:39 pm

    Hey Katie!  I’e never tried it, but I bet you could — I’d lower the amount of butter if you’re using spread instead of raw hazelnuts, but I bet it would work!
