Flourless chocolate cake with ganache is a gluten-free and very decadent dessert that's surprisingly easy to make!
Over the years, we've received many rave reviews on this flourless chocolate torte with a silky dark chocolate ganache topping. It does not disappoint.
This reader comment just about sums it up:
"My husband has been describing an extremely dense and super chocolatey cake for years. I have probably bought dozens of them and made dozens as well. This is the only cake that is exactly what he was looking for! I am so thankful for your post! It’s going to be my new holiday bring!" -Jeana
More recently, I've experimented with different flavored chocolate bars to make variations like Flourless Orange Chocolate Cake. It's hard to pick which one to make for special occasions and holidays, like Valentine's Day or Mother's Day.
And I owe it all to Whole Foods' flourless cake recipe, which inspired this one. It's straightforward, simple and delicious.
If you're a chocolate lover, it's the perfect dessert. It's so rich and satisfying that you can...you must...stop at just one slice!

Ingredient Notes
These are the simple ingredients you need to make both the flourless chocolate cake and the decadent chocolate ganache frosting:
- Dark or bittersweet chocolate (bars or chips) - Look for 70% cacao content or higher. Semi-sweet chocolate with about 60% cacao can be used instead for a slightly sweeter version.
- Note: Ghiradelli and Lindt Chocolate Bars are 3.5 ounces each. So, you'll need 2 full bars plus 2 squares for the cake. The ganache requires 1 bar plus 1 square. I often add a few chocolate chips to get the total amount needed. You'll need 3 bars plus 3 squares in total.
- Sugar - Or use my sugar compromise, half refined sugar and half of a dry stevia sweetener blend, to lower sugar content and carbs.
- Unsalted butter
- Unsweetened cocoa powder - Use Dutch-processed cocoa for a deep chocolate flavor.
- Heavy cream, half and half, or any milk - The higher the milkfat, the creamier the ganache!
- Honey is used to sweeten the ganache. Sugar can be used instead, and the sweetener can be omitted if semi-sweet or milk chocolate is used.
Please refer to the recipe card below for the full list of ingredients and detailed instructions.
Equipment
No electric mixer is needed to make this easy recipe! However, a springform pan makes the cake release quickly and easily.
A standard cake pan can be used instead. Use a silicone spatula to gently ensure that the cake does not stick to the side before inverting.
Directions with Pictures
Follow these steps to make the best flourless chocolate cake recipe and the chocolate ganache.
To make the flourless chocolate cake:
Line the bottom of a springform cake pan with parchment paper. Spray the sides of the pan and the parchment paper with cooking spray. Sprinkle cocoa powder on the bottom of the pan if desired.
Break the chocolate into pieces and slice the butter into segments. Melt chocolate and butter in a medium saucepan over medium-low heat, stirring to thoroughly combine.
Note for step 2: The chocolate and butter may also be melted in the microwave. Add to a microwave-safe bowl and heat at short 30-second intervals until blended and smooth.
Transfer the melted chocolate and butter mixture to a large bowl. Add sugar and mix to combine.
Add eggs one at a time, whisking thoroughly into the mixture before adding the next egg. The mixture will become increasingly thicker. I find it easier to whisk all of the eggs together in a large measuring cup and slowly stream them into the batter.
Add cocoa powder in quarter cup increments until combined.
Pour the chocolate mixture into the prepared pan and smooth it out with a knife.
Bake at 375°F for 35-40 minutes for a 9-inch round pan or 25-30 minutes for a 10-inch round pan or until the cake is firm in the center and a toothpick comes out clean.
Cool for about 10 minutes, and then remove the sides of the pan and invert onto a plate. Remove the parchment paper. The bottom is now the top of the cake.
To make the ganache:
Melt butter and chocolate in a saucepan and stir to thoroughly combine. Mix in cream, vanilla extract, and honey. Set aside to cool slightly.
Once the cake has completely cooled, spread the chocolate ganache glaze over the flourless chocolate cake, using a spatula to cover the top and allowing it to drip down the sides. It will firm to a fudge-like consistency when fully set, which can take several hours.
Optional garnishes for the top of the cake: Fresh raspberries, strawberries, or other fresh fruit, powdered sugar, or whipped cream. It's also lovely with a scoop of ice cream!
Top Tips
Use a sharp knife dipped in hot water and wiped dry to cut perfect, clean slices. Repeat between slices.
Storage
Below are guidelines and tips for storing flourless chocolate cake with a ganache topping so it's as tasty as the day you made it.
- Room temperature: Store for about 24 hours, covered with a dome to prevent the ganache frosting from drying out.
- Refrigerator: Store covered for 4-5 days.
- Freezer: Chill in the refrigerator first, then cover with plastic wrap and aluminum foil. Store for about 2 months. Consider cutting first and storing individual slices!
- Covering tip: Allow the ganache topping to fully set if covering the cake in plastic wrap.
- Serving tip: Allow flourless cake to sit at room temperature for at least 30 minutes before serving.

10/10 Excellent!! Was looking for something special for Valentine's Day, this was IT!
Simple recipe, easy to follow, pictures and tips were so helpful.
I used Ghirardelli chocolate bars and cocoa powder. I also browned the butter for the cake, cooled it a bit and the chocolate melted perfectly. I also used half brown sugar and half turbinado sugar. Ridiculously smooth and rich and the flavor depth was incredible.
Thank you for such a fantastic recipe!
Marjory Pilley says
I’m so happy you enjoyed it and sharing your experience. It sounds absolutely decadent.😍
Theresa says
Is all the butter in this recipe unsalted?
Marjory Pilley says
Yes! It’s best to use unsalted butter.
Ally says
I searched the page several times and for some reason I am not seeing the cream measurement for the ganache. Can someone share the proper amount of cream to use in addition to the milk listed? TIA
Marjory Pilley says
Hi! 1 Tablespoon of milk (or any type of cream such as heavy cream or half and half) is used in the ganache. Thanks for your comment!!! I updated the instructions to make it clear.
Tesa says
Best gf chocolate cake EVER!
Carol Young says
Wonderful cake. I always make this for my granddaughter for her birthday. She loves it because it’s sooooooo rich. I’ve made it about 20 times over the past 6 or 7 years and always perfect. The ganache is the perfect touch! Thanks for a great recipe.
Marjory Pilley says
I’m so glad you and your family enjoy it! And thanks so much for sharing your experience.

Teresa says
Hello! I was wondering if you have ever made little versions of this in a cupcake pan before?
Marjory Pilley says
No I haven't. But, it would be a great one to try!
Trish Gaudio says
Concerning the chocolate...I'm confused...is it bittersweet chocolate or dark..or are they the same thing? I guess it would help me to know the percentage of cacao in the particular chocolate you used.
Marjory Pilley says
Hi! I usually use 70% cacao chocolate bars in this recipe. I used Lindt in this case! I hope you enjoy it!
Jeanna says
My husband has been describing an extremely dense and super chocolatey cake for years. I have probably bought dozens of them and made dozens as well. This is the only cake that is exactly what he was looking for! I am so thankful for your post! It’s going to be my new holiday bring!
Marjory Pilley says
Thank ou so much for sharing! I'm so glad you found it!
Mady Starke says
In the recipe for the cake, is it 1 cup *and* 2 sticks of butter, or 1 cup=2 sticks of butter?
Marjory says
Hi! 1 cup usually equals 2 traditional sticks of butter, but always check the packaging.
Jennifer says
I wanted to make something that's not the norm for me. I'm always on the hunt for GF recipes as my sister is GF in her diet. I'm the experimenter,if it's good I pass it on to her.
Not only was this cake super easy to put it together but oh so rich and beautiful looking.
I love the idea of a ganche with honey in it.
I baked mine for 40 minutes using a 9 inch springform pan.
Everyone loved it, simply amazing!
Marjory says
Yay! I'm thrilled that you liked it! I recently tried it using dark orange chocolate barks and it was delicious too...in case you want to experiment some more!!!
Judi Hubbard says
Can I make this day prior to serving ??
Marjory says
Hi! Absolutely this can be made in advance and stores well.
Sandi says
Hi! I couldn’t find what size of spring form pan...9”?
Marjory says
Hi! Yes 9 inch spring form pan. A 10 inch pan will also work, just adjust the time down about 5-7 minutes.
Sandi says
Thank you!!!
morgue anna says
Do you have suggestions to turning this into a springform mini recipe? I have 4" mini springform pans to make individual desserts to take to friends. How could I convert the baking time of this recipe? thank you!
Marjory says
Hi! I have not tried this, but you should be able to divide the batter between smaller pans. Keep an eye on the cook time as it may take less time. Good luck!
Karen says
I made this for the first time last night for company and it was a huge hit. My husband said it was better than any flourless chocolate cake he has had in any restaurant.
Marjory says
I'm so glad you liked it! Thanks for your feedback...made my day!
Wendellyn Plummer says
I am so excited to make this. My Mother's 91st birthday is coming and I am GF. It is very hard to get a GF desert in Restaurants. I will be doing a dry run tomorrow. Thank you in advance!!!!
Marjory says
I hope you enjoy it! 🙂
Anne says
Made this cake for Christmas, and of course, it was a hit! Was so glad it was shared with me, as I am gluten-free. No way to improve on it - it's perfect! Sharing your recipe, and can't wait to make it again1
Marjory says
I'm so glad you enjoyed it!
Paula B. says
I searched high and low for a variation on the usual flourless chocolate cake recipe I make and found yours. It came together beautifully and the topping was so simple and delish. Everyone wanted another piece to take home! One problem, though, the cake sank slightly on top - yours looked so even, do you ever have this happen to you?
Marjory says
Thanks so much for your comment! I have not experienced the top sinking, but I'm wondering if it needed to cook just a bit longer?
Paula B. says
I followed the directions and it certainly appeared thoroughly cooked when sliced. No worries, the main thing was how unbelievably good it tasted. And, that ganache was so decadent yet easy to make, I am going to use it with some of my other recipes as I don't always have cream in the house.
Grace says
This recipe is by far the best chocolate cake I have ever eaten or made. So so so rich and delicious! Every time I make it I get rave reviews and it couldn't be easier! I highly highly recommend to anyone! I add sea salt on top of the ganache for an extension ra zing! To die for!!!
Marjory says
I'm so glad you liked it! Definitely adding a little sea salt next time!
dina says
i love the richness of flourless chocolate cakes. this looks amazing!
Marjory says
Thanks! It's definitely decadent!

Your cake sounds tasty, wish I had a slice.
