Chocolate lovers will adore this dessert. The edges and top develop a delicately crisp crust while the center remains moist and fudgy.

Ingredients

Ingredient Checklist

Directions

Instructions Checklist
  • Preheat the oven to 275 degrees with the rack in the center. Butter the bottom and sides of a 9-inch springform pan. Set aside.

    Advertisement
  • Place butter and chocolate in a large heatproof bowl and microwave in 30-second increments, stirring each time, until completely melted. Let cool slightly. Whisk in egg yolks.

  • In a large bowl, beat egg whites until soft peaks form. Gradually add granulated sugar, and continue beating until glossy stiff peaks form. Whisk 1/4 of the egg whites into the chocolate mixture; then gently fold in remaining egg whites.

  • Pour batter into the prepared pan, and smooth the top with a rubber spatula. Bake until the cake pulls away from the sides of the pan and is set in the center, 45 to 50 minutes. Cool completely on a wire rack; remove sides of pan. Serve at room temperature, dusted with confectioners' sugar. Serve with whipped cream, if desired.

Made this tonight and since I'm on a ketogenic (low carb/no suger) diet I had to make several adjustments. For the chocolate I substituted Hershey's sugar free morsels. Instead of regular sugar I used 1/4 cup of Monk Fruit. I didn't need more "sugar" as the morsels have sugar alcohols. I did add a few tablespoons of heavy cream and coconut flour for texture. It turned out great! Rich and delicious. Next time I'll add some espresso freeze dried granules and cinnamon. Just tweeks really.

Outstanding. This is our family go-to celebration cake. It is straightforward, unfussy, elegant. Use great quality belgian dark chocolate (callenbault) and wait for the applause. Truly, this cake never fails to impress—it is light yet luscious, intense yet delicate. Perfect.

I have made this cake several times & will be making it again next weekend! It's easy and always turns out fabulous! I always use fresh eggs, butter and the best chocolate I can find. One time, I was short on chocolate and found some old raspberry flavored chocolate chips in the pantry, so I threw them in.... the cake was still great & had that hint of raspberry flavor.

Very yummy! Just followed this because I was craving a treat which is not easy on Passover! Easy to make. I didn't have enough chocolate so I subbed 4 TBS baking cocoa powder and it turned out. Also used non-dairy margarine and it did not impact the final product. This would probably be tasty with coconut oil instead of butter and coconut shavings. My only comment is that if you want this to be kosher for Passover, use kosher for Passover powdered sugar. Regular powdered sugar has cornstarch which is not kosher for Passover. Kosher for Passover powdered sugar uses potato starch. Honestly, this has a lot of protein and not that much sugar. Probably healthier than a Clif bar!!!

Amazing cake! Light- almost like a souffle. Easy to make. The high protein, no flour, low sugar will make this cake my new goto easy dessert.

I really goofed and left half the chocolate on the counter. But the cake worked great without it. It rose perfectly and had a light airy texture and I did not miss the extra chocolate. In fact I think that might have made it too dense and rich. I love my augmented recipe.

I just forgot to say that I didn't have a springform pan (hope Martha isn't listening) so I made it in the only available dish: an 8 inch square pyrex casserole type dish... And it still turned out just the way Martha Stewart said it would...So don't be leery of trying it, okay?

I made this first ever flourless cake, for a friend with Celiac's. She loved it! So did I! I used Ghiradelli Bittersweet chocolate, which gave the cake a deep dark chocolate flavor. The cake is scrumptious in texture (soft angelfood-cake texture inside, crispy outside) and easy-peasy to make. Mmmmm-Yum!

In the event you choose to make this cake, despite my previous warning (ha!) -- two things: (1) you do not need to line your springform pan if it's a no-stick one. (2) Baking temp was not too low for my electric oven - followed instructions exactly, and it did cook thoroughly. I was just very disappointed in the taste. I would look into adding cocoa powder -with adjustments to accommodate the addition.

The cake looks very attractive when it comes out of the oven, I'll give it that. Sadly, the flavor is so bland and blah - lacks any richness of chocolate. Nearly flavorless. :( Followed instructions to the "t" (experienced baker). I chose this because it was easy and I needed something chocolate in a "pinch" to go with homemade ice cream. I will use a recipe that calls for cocoa powder as well as other ingredients (liquor, coffee, etc) that give it more punch. Do not recommend this recipe.

I literally JUST made this cake (just took it out of the oven) for Easter dessert tonight. It looks and smells delicious! I followed the recipe exactly - I used semi-sweet chocolate and baked it for 45 minutes. It is currently sitting on a cooling rack and the middle is cracking and dropping just like in the photo. I'll be serving it with French vanilla icecream. Can't wait to eat this with my family later today! Great and easy recipe!

Absolutely fantastic cake. I made it with 72 percent cocoa chocolate. All my guests loved it. Instead of serving with whipped cream I put a few fresh raspberries on the side and the taste combination was excellent and it looked really beautiful served with them.

The cooking temperature was too low. Needs to be at 350+ to get that crispy crust. Unless you are using a confection oven...

Recipe is not the recipe on the TV show. Instructions are problematic: when you write a recipe your readers rely on you to make the instructions clear enough to avoid mistakes on recipes they've never used before, like saying the chocolate/butter mixture should be at room temperature or lukewarm at the very most

After wasting 2 dozens eggs, I had the patience to look through about 20 reviews right here and someone mentioned that this recipe will never work unless the butter and chocolate mixture is cooled to room temp. My 24 yolks CURDLED in the previous 4 attemtps not unlike the omelette recipe :-). To re-iterate, the recipe will work fine if you cool down the chocolate/butter mixture after double boiler. As a side note, I had to downgrade the chocolate from 70% (too intense and bitter) to 45-50% cocoa

Yum! I do not have a springform pan, used a brownie type dish instead, we cut slices from the pan so it worked out fine. For the final step, I took the cooled chocolate mixture and mixed it into the egg whites with the mixer set on fold and it came out perfect both times I have made this. Will make again for company.

This recipe was very easy to make! It isn't an expensive recipe to make, as it doesn't require much! I would definitely make this one again, I do plan on playing with the butter to chocolate ratio because I found it to be a bit too rich compared to the crusty exterior! *Tip: Don't be nervous when you see large air bubbles or the cake expanding too much out of the pan, it will sink down into what the picture looks like!*

This turned out delicious! I was worried at first because the cake cooked up over the top of the round and did not 'pull away from the sides' like the recipe mentioned, but once it sat and cooled, it sank down into the delicious dense cake I was after. I did a total of 50 minutes baking time. I tempered the eggs, added a little chocolate to the yolks, before mixing them into the chocolate. I served it with a raspberry sauce and it was a HUGE hit! Will make again!

Dear noele12, If the chocolate mixture were cold it would be hard and very difficult to whisk egg yolks into. I would recommend 1st, melting the chocolate and butter until warm but not liquid hot for the chocolate; stir more and heat less. 2nd, let this mixture sit while you attend to the whites. Then 3rd, whisk in the yolks just before the whites. I have made this recipe several times in varied climates and never had it fail, though it is in nature not a tall cake. Good luck.

This recipe is a faliure. dont attempt it. The recipe needs to be re-written to explain that the chocolate mixture needs to be COLD before you mix the egg yolk! I attempted it twice and wasted alot of money. Very dissappointed!!!

i've made this many times. sometimes it looks exactly like the picture and sometimes it doesn't. always tastes great. except for the time i was in a rush and added the eggs to the chocolate when it was too hot, thus cooking the eggs. not so good. I always serve it with a flavored fresh whipped cream. Raspberry is my fav, but you could go any direction with that.

I like the simplicity of this cake; however, I think that I will add cointreau/grand marnier,(with orange/lime zest) rum, or lavander to this to see how it comes out. I am not too fond of a lot of white sugar (sugar substitutes. excluding fruit-based/honey-based that I have tried are terrible in taste and in its' composition) but , I guess, it is a necessary component of making desserts.....just wish we didn't need so much of it to bake with.

Have tried two recipes. For a neater looking presentation, no cracks, and foolproof outcome use the recipe from Cook's Illustrated instead. (No messy top. No sugar in the recipe. No guessing - internal temp of 140 is all that's needed.) With a little added coffee or coffee liqueur the chocolate flavor really charges through.

This cake turned really well. I used 70% dark chocolate bars to give a deep and rich chocolate flavor. I served it alongside a dollop of amaretto mascarpone cream, which gave a smooth finish. It's easy to make and will impress.

I've made this recipe a few times now and it's always come out perfect and looks exactly like the photo. This time I'm going to sneak in a small amount of cinnamon to see how it is. It looks like a much more involved recipe than it truly is and yes, the previous poster said to let the cake cool completely before removing it from the spring form pan, she's correct. It will crack otherwise. Best, Priscilla Sanctuary Design Portland, Maine
