Flourless Chocolate Cake

If you follow me on Instagram, you may remember me posting a piece of flourless chocolate cake while dining at The Capital Grille. After one bite, I was smitten with the rich, dense espresso infused chocolate cake.

When Shaina’s debut cookbook, Desserts in Jars arrived on my doorstep, I immediately honed in on page 35 – Flourless Chocolate Cakes, beautifully photographed in my favorite Weck jars. Shaina described her Flourless Chocolate Cakes as little brownies with crunchy tops and that’s exactly what they taste like. Pure chocolate perfection in an adorable glass jar.

[pinit] In you visit MBA on a regular basis, you know how much I love baking and presenting desserts in jars, so naturally, I was incredibly excited about Shaina’s cookbook. Desserts in Jars contains 50 gorgeous recipes including cakes, pies, puddings, frozen desserts and even a variety of mixes that are perfect for giving.

Shaina expertly walks you through the process of choosing, filling, baking and even adorning your jars with printable tags, so they’re ready for a casual backyard barbecue or a fancy holiday party. And after hanging out with Shaina in NYC, I must say, Desserts in Jars is an accurate representation of the awesomeness that is Shaina.

Flourless Chocolate Cakes

Yield: 14 individual cakes

Prep Time: 10 minutes

Cook Time: 20-25 minutes


Oil for greasing the jars
7 ounces bittersweet chocolate
4 tablespoons (½ stick)unsalted butter
1 cup granulated sugar
4 large eggs, separated
Confectioners’ sugar, for dusting
fresh raspberries for garnish


1. Preheat the oven to 350ºF. Grease fourteen 8-ounce jars. In a double boiler over simmering water, melt the chocolate and butter until smooth. Remove from the heat and allow to cool slightly. In a separate bowl, use a hand mixer to beat the egg whites until stiff peaks form. Set aside.

2. In a stand mixer, beat together the granulated sugar and egg yolks until thick and creamy. Mix ¼ cup of the melted chocolate and butter into the egg yolks. Continuing to mix, slowly pour the remaining melted chocolate mixture into the egg yolks until all is incorporated. Fold the egg whites into the chocolate mixture.

3. Spoon 4 to 5 tablespoons of the cake batter into each greased jar. Place the jars 2 inches apart on a baking sheet. Bake for 25 to 30 minutes, until the tops of the cakes start to crack. Remove from the oven and let the jars cool. Dust with confectioners’ sugar before serving. Serve warm or at room temperature. If desired, garnish with fresh raspberries.


- This recipe works well when cut in half.
- Jars seen in the photos are Weck Mini Mold Jars #976-165

    I’ve had so many wonderful desserts! My granny was a great baker. She taught me how to bake, and passed on her pie making secrets to me. I’d have to say her fresh cherry cream pie is my home-cooked favorite. I had a key lime cupcake at a local cupcakery that I can’t sot thinking about, so that is probably the best take-out dessert.

    best dessert…..my grandmas apricot cobbler or her rhubarb pie…..she had a beautiful apricot tree and a big rhubarb patch….


  3. Deborah Sundes — November 27, 2013 at 10:23 pm

    My favorite desert was banana pudding made with vanilla wafers. Brings back the best memories of my child hood.


    • Jamie — December 4, 2013 at 4:46 pm


      Yum, one of mine too! Have a great day and thank you for following MBA!


  4. Bruno Sandes — January 6, 2014 at 4:21 am

    The best desert I’ve ever tasted was a Chocolate and Passion Fruit Parfait the last time I went to Brazil.
    The mix of chocolate and passion fruit is just amazing! It mixes the delicious and refined taste of chocolate with the tropical savor of passion fruit! Superb!
    Unforgettable taste! The chef gave me the recipe and it is so easy to make!

    P.S.: Congrats for your website, I’m a straight guy who lives by himself and who loves cooking. Your website has helped me and taught me amazing things! Thank you so much!

      That sounds amazing! Thank you so much for stopping by and for following MBA! Have a fantastic day!


  6. Leslie — February 11, 2014 at 3:23 pm

    Wondering if the flourless chocolate cake can be made in round cake pans or as a sheet cake?


    • Jamie — February 11, 2014 at 8:12 pm

      Leslie, you could certainly try. The recipe is written specifically from a book that separates desserts out into jars, so I can’t speak to how that would turn out, or if the yield would be enough for a sheet cake. Experiment though! Don’t be afraid to do that.

      Along the same lines, do you think this recipe would work well as a cupcake? My cousin and her family are all gluten free and we are having a birthday party for my son that they will be attending. I want her kids to be able to have cupcakes with everyone else without me having to go nuts buying specialty ingredients.

    • Jamie — November 19, 2014 at 12:09 pm

      You should be able to use the same recipe for cupcakes but you will likely need to adjust the cooking time.


  7. Debbie Rael — March 13, 2014 at 12:49 am

    My mother in law’s no bake lemon cheesecake.


  8. Dora — March 13, 2014 at 12:58 am

    Anything chocolate, dark chocolate. One favorite is a rolled pound type cake with chocolate inside! But the jars, I love the jars, I have so many canning jars, use them for lots of stuff.


  9. Suma john — March 13, 2014 at 12:49 pm

    The best dessert I like is an Indian sweet – LADOO. It is yellow in colour and melts in the mouth


  10. Brittney landrau — March 13, 2014 at 3:23 pm

    My best dessert I ever had was a hot chocolate chip cookie orrrrr a hot brownie/chocolate cake with some vanilla ice cream in top and whipped cream!!! The hot and cold!!! The vanilla and chocolate!! Like having cookies and cream! Love it


  11. Susan Kline — March 14, 2014 at 5:27 am

    Anything dark chocolate! This flourless cake recipe definitely sounds like a keeper. And in little jars? Perfect portion control!


    • Jamie — March 19, 2014 at 11:23 am


      Thanks so much for stopping by! And, the portions help…until you eat two or three :). Have a great day!


  12. Saida — May 3, 2014 at 7:45 pm

    Made these tonight. They where awesome. Only thing is next time I’ll cut back on the sugar maybe 3/4cup. But other than that this is a keeper. Thanks


  13. Sheryl — June 19, 2014 at 6:27 pm

    I made a flourless chocolate cake for Father’s Day, using a recipe posted on “skinney tastes”. Can’ wait to try your recipe! It is my families favorite dessert now! Yours looks wonderful!


  14. Kristy — August 5, 2014 at 9:30 am

    My favorite desert is a pie inspired by a Hawaiian tropic after tanning lotion called lime coolada , it is a pina colada- key lime pie, that I created, because nobody else wanted to tackle it.


  15. Jaimi Sherman — August 11, 2014 at 9:14 pm

    Loooooove Sticky Toffee pudding!


  16. Lisa Green — August 11, 2014 at 9:15 pm

    My Mom always made the most delicious lane cake, once a year, around the holidays.


  17. Julia Torres — August 11, 2014 at 9:25 pm

    Best dessert ever would have to be lemon squares tarts goodness!♡


  18. Linda Schuck — August 11, 2014 at 9:28 pm

    This recipe reminds me of one of my favorite desserts,Chocolate Raspberry Truffle Wedge! Chocolate truffle cake with a delicious raspberry sauce!


  19. Meghan — August 11, 2014 at 9:33 pm

    Ghiradelli stuffed brownies! The caramel infuses through the whole brownie!


  20. Linda — August 11, 2014 at 9:44 pm

    My favorite dessert is Kentucky Derby Pie.


  21. Donna — August 11, 2014 at 9:53 pm

    The best dessert I’ve had is the Bread Pudding with Hot Whiskey Sauce in New Orleans, LA. My husband and I were staying at the Hyatt Regency and we ate at the restaurant in their open courtyard area. Wherever we have traveled, I will try the bread pudding and none have come close to what I ate at the Regency. It was cut like a slice of pie and it was very dense.


  22. 3petitsprinces — August 11, 2014 at 9:59 pm

    Best dessert ever…hmm…that is a real tough one! Crème brûleé? Brownies with ice cream? My most memorable one for sure was homemade raspberry sorbet made with freshly picked raspberries in Alsace, France when I was 16.


  23. Madeline — August 11, 2014 at 10:15 pm

    One of the most memorable desserts I’ve had was a tall, thick slice of a flourless torte from a small, Italian restaurant I ate at years ago. I’ve even dreamed about it because its rich flavor and dense texture made it a rare moment of decadence. Also can’t wait to try your recipe!


  24. Wendy Gaines — August 11, 2014 at 10:16 pm

    My all time fav dessert is creme brûlée. I have never tasted one I didn’t enjoy.


  25. Kristen Acosta — August 11, 2014 at 10:23 pm

    The best dessert I’ve ever had was the sweet and salty chocolate cake from Baked bakery. So delicious!!


  26. Heidi — August 11, 2014 at 10:23 pm

    Best dessert is a toss up between my wedding cake with fondant and sugar coated champagne grapes or ginger spice cookies. Both made by one of my aunts.


  27. Cheryl N. — August 11, 2014 at 11:24 pm

    Oh, how does one choose a favorite dessert? Anything chocolate but lemon bars and key lime pie are at the top also. I’m a dessert addict but have never made flourless chocolate cake. It’s on my list to try!


  28. Heidi Mahon — August 12, 2014 at 12:09 am

    Fall is my favorite season and my favorite dessert goes right along with it. Pumpkin bread pudding with caramel sauce!


  29. Melissa Moyers — August 12, 2014 at 12:13 am

    Olallieberry pie with vanilla bean ice cream!


    • Jamie — August 12, 2014 at 10:17 am

      That sounds wonderful. Thanks for stopping by.


  30. Elena Davis — August 12, 2014 at 12:37 am

    My homemade cinnamon buns with a buttery butterscotch whiskey sauce are mind blowing! I bet I could get them in a jar!


  31. Elizabeth — August 12, 2014 at 1:24 am

    My favorite dessert is fresh lemon cupcakes with a fresh lemon buttercream garnished with a little sugared lemon zest. I tweeked a basic recipe and added my own touches…they are delish!!!


    • Jamie — August 12, 2014 at 10:13 am

      So glad they were a success! Thanks for stopping by.


  32. Sarah — August 12, 2014 at 11:36 am

    Best dessert?? So hard to answer. But I think those made with lots of love are best, like my friend’s lemon semi-freddo that she made my daughter for her birthday, or the lime buttermilk panna cotta made by a friend for her husband’s 50th birthday dinner party. Guess the trend for me is citrus!


    • Jamie — August 12, 2014 at 8:15 pm

      I love citrus desserts too, thanks for stopping by.


  33. Sally — August 12, 2014 at 12:46 pm

    Favorite recipe is one my mom and I got from a chef in Florida. It’s a flourless chocolate espresso torte it’s so good!!!! It’s our go to dessert. :0)


    • Jamie — August 12, 2014 at 8:10 pm

      Sounds wonderful, thanks for stopping by.


  34. Thom — August 22, 2014 at 8:56 am

    My absolute favorite dessert is My TIRAMISU! So lite, airy and delicious. It takes quite a while to prepare but well worth the effort. My question is 4 or 5 tbsp of mixture in an 8 ounce glass? It dosen’t seem like much batter. In the link for the jars the largest jar is 5.6 ounces. I’m confused. Thank you.


  35. vickie gale — August 22, 2014 at 9:44 pm

    My favorite dessert was my grandmother’s icebox cake. It was an angel food cake, layered with chocolate pudding in a spring mold. After properly setting up, it was served with heaping spoonsful of whipping cream. Incredible. My mother hoards the recipe and inserts red herrings into the recipes she does share with us. The results are less than satisfactory.


    • Jamie — August 23, 2014 at 8:52 am

      Your grandmother’s icebox cake sounds wonderful. Thanks so much for stopping by.


  36. Angela — August 27, 2014 at 8:07 am

    My mother’s old fashion fudge… Hands down ..the very best! Miss that every year now.


    • Jamie — August 27, 2014 at 10:13 am

      Old fashioned fudge is the best! Thanks for stopping by.


  37. Matse — February 5, 2015 at 12:53 am

    This looks so delicious and mouth watering. Made without flour too? This is heaven!


    • Jamie — February 5, 2015 at 9:07 am

      Thanks so much for stopping by!


  38. Claire — February 26, 2015 at 11:31 pm

    I made this today – it was wonderful! This was the first time I had made a ‘flourless’ cake, and I was skeptical that the texture would be similar to a ‘flour’ cake. I was pleasantly surprised that the texture is very similar to a cake made with flour – very decadent! Thanks for this great recipe.


    • Jamie — March 1, 2015 at 9:33 am

      I’m so glad you had success with the recipe. Thanks for stopping by.

  40. Hannah — April 3, 2015 at 8:50 am

    Hi, is it possible to prep these in advance into the jars, refridgerate and cook before serving? Or suggestions how to warm up before serving? Hoping to bake these tonight :) Thanks!


    • Jamie — April 6, 2015 at 11:34 am

      I would recommend mixing these just before baking. I hope this helps.


  41. Vince — July 29, 2015 at 10:17 am

    Has anyone tried to adapt this to sugar free by substituting Stevia?


  42. Coco in the Kitchen — October 2, 2015 at 5:44 pm

    Adorable. Delicious. I must make these li’l cuties!


  43. Evie Metcalf — February 2, 2016 at 10:53 am

  44. Angel — October 10, 2016 at 3:49 am

    I just tried your flourless choc cake in jars need to know it was crispy on top n like very soft inside like a jelly type  . Was it suppose to be like that or did I go wrong some where 


    • Jamie — October 11, 2016 at 8:51 am

      Hi, Angel! The cake should be like a dense brownie. Maybe bake for a bit longer? Let me know the outcome if you give it another try!

  45. Lisa — October 22, 2016 at 6:19 pm

    I love Weck jars and I’m looking forward to trying this. I have the same Weck Mini Mold Jars #976, which are 5.6 oz. The recipe calls for 8 oz jars. Did you put less than 4-5 tablespoons of batter per jar? I want mine to look like your  great photos–full but not overflowing!


    • Jamie — October 24, 2016 at 12:19 pm

      Hi, Lisa! You should definitely put less than four to five tablespoons. Try three and go from there. Let me know how everything turns out!
