3-Ingredient Flourless Chocolate Cake

The best flourless cake recipe — easy to make with just 3 ingredients, and so irresistibly delicious!

This past Valentine’s Day, I decided to remake a golden oldie from the blog to share with my friends. Partly because it was super easy. Partly because it’s gluten-free. And partly because, well, it’s about as chocolatey as you can possibly get.

We’re talking about flourless chocolate cake, people!

I’m sure just about everyone has tried this heavenly dessert before. But if you’ve never tried making it, you’re missing out. Because with literally just three ingredients, it’s totally do-able. And just in case you have any questions about how to make it, I decided to snap some step-by-step photos time time around and update this recipe post so that you can see exactly how it’s done.

Fair warning though. Once you know how to make this cake, you’re pretty much going to want to make it all the time. :)

(Works for me, though!)

3-Ingredient Flourless Chocolate Cake

  • Prep Time: 15 minutes
  • Cook Time: 25 minutes
  • Total Time: 40 minutes
  • Yield: 12 servings 1x


A decadent, gluten-free flourless chocolate cake recipe with no added sugar necessary!


  • 8 large eggs, cold
  • 1 pound dark, semisweet or bittersweet chocolate, coarsely chopped
  • 1 cup (2 sticks) unsalted butter, cut into 16 pieces
  • optional toppings: powdered sugar and berries


  1. Adjust an oven rack to the lower-middle position and heat the oven to 325°F. Line the bottom of an 8-inch springform pan with parchment paper and grease the sides of the pan. Center the pan on a large sheet of heavy-duty aluminum foil and wrap the edges up around the sides of the pan. Repeat with a second sheet of foil. Set the pan in a large roasting pan, or any pan that’s larger than the springform. Bring a kettle or pot of water to boil.
  2. In a stand mixer using the whisk attachment, beat the eggs at high speed until the volume doubles. This usually takes about 5 minutes.
  3. Meanwhile, melt the chocolate and butter together. You can either do this in a double boiler on the stove (by placing the chocolate and butter in a large heatproof bowl, set over a pan of almost-simmering water, and stirring until melted and smooth). Or you can do this in the microwave (by heating the chocolate and butter in a microwave-safe bowl in 30-second intervals, stirring in between, until the chocolate and butter are melted and smooth). Take care not to overheat the chocolate – you only want to heat it enough so that the chocolate *just* melts. 
  4. Fold about a third of the beaten eggs into the chocolate mixture using a large rubber spatula until only a few streaks of egg are visible. Fold in half of the remaining egg foam, and then the last half of the foam, until the mixture is totally homogenous. Do not overstir.
  5. Scrape the batter into the prepared springform pan and smooth the surface with a rubber spatula. Place the roasting pan on the oven rack and VERY carefully pour in enough boiling water to come about halfway up the sides of the springform pan. Bake for 20 minutes. Carefully remove the springform pan from the water bath and set it on a wire rack; cool to room temperature. Cover and refrigerate until cool. 
  6. About 30 minutes prior to serving, run a knife around the edges of the cake and carefully remove the sides of the springform pan. Carefully slip a spatula under the parchment to loosen and remove the pan base and transfer the cake to a serving platter. If desired, lightly dust the cake with powdered sugar and top with berries. To slice, use a sharp, thin-bladed knife, dipping the knife into a pitcher of hot water and wiping the blade before each cut.

  1. Looks great! I posted a 4 ingredient flourless peanut butter cookie the other day on my blog! We all are on the same page it seems!!! :)

  2. looks sooo amazing! Love the clicks too.. just amazing.

  3. That looks (and sounds) amazing! I have a friend who is allergic to gluten–I’m definitely going to share this recipe with her! Of course, she’s also allergic to soy BUT we’ve found a soy-free chocolate that is delicious…I’m thinking substitution! Thanks so much for sharing!

  4. Ooh, you had me at “3 ingredients” This looks amazing!

  5. Can you further explain “Place the roasting pan on the oven rack and pour in enough boiling water to come about halfway up the sides of the springform pan.”?

    • Hi Haley!

      Yep – it’s basically a water bath where you put the springform pan actually IN the water.

      So you place the springform pan (wrapped in foil) in the roasting pan. Then fill the roasting pan (not the springform) with boiling water until it comes up to about the halfway point on the height of the springform pan. Then let it bake. And when it’s done, you’ll carefully remove the springform from the roasting pan that was filled with water.

      Let me know if you have any more questions! Sorry – it’s a little weird and confusing, but works really well!


  6. I am so excited about this recipe. I have a gluten-free friend and this would be the perfect dessert the next time she and her chocolate lovin’ hubby are over for dinner. Thanks for this post!

  7. I will be trying this for sure!

  8. This was amazing! I loved it with the strawberries.

  9. Now that is a plate of beauty! :)

  10. I made this recipe yesterday, but mine looked different. When you whipped your eggs, what did it look like after the 5 minutes? Mine looked like scrambled eggs with some air bubbles on top. Also, did your cake taste like a piece of chocolate fudge? Mine didn’t have any cake like texture at all and I think it might be due to the fact that I didn’t beat the eggs at a high enough speed.

    • If your eggs looked like scrambled eggs, it seems you didn’t separate the yolks from the whites and use only the whites.

    • This recipe seems to call for the whole egg, not just the whites. You can see them in the picture.

    • You want to mix the eggs at the HIGHEST SPEED POSSIBLE with an electric mixer for 5 solid minutes, it will double (or triple) in mass just like the original recipe said! :)

  11. I made this and had to throw it out. It was not sweet. I made it a second time adding over 1/2 cup of sugar and this time boyfriend said it was great and asked that I make it again…

    • Did you happen to use unsweetened chocolate instead of dark chocolate? It’s not intended to be a super sweet cake but should be sweet enough with the correct chocolate.

  12. oi – i tried this recipe but the water bath thing so did not work for me. I wrapped my springform pan in 3 layers of foil, but water still leaked into the cake batter and ruined the whole thing :(

  13. I’ve never baked before, so this was my first cake EVER! I love the simplicity and like to stick with very few ingredients. I halfed the recipe and used Trader Joe’s semi-sweet choco chips. It was perfect! Thank you!

  14. I just melted and mixed and baked,simple and easy ,turned out great!

  15. Un salted butter is not gluten free!

    • Hi Paula, can you tell me where you got that from? I did some research and everything I read said it was gluten free. Is it a certain brand? Thanks!

    • Unsalted Butter just means its butter without salt in it, there is no gluten in butter (salted or unsalted)

    • un-salted butter is inherently gluten free as it’s just cream. Salted butter is also inherently gluten free as it’s just cream and salt, nothing else.

  16. I’ve been looking for some gluten-free (and sugar-free)recipes for our church bake sale and this looks great. Do you know if it can be frozen, and how long it will keep? Hope you can answer cause I really hope to do this cake. TY

  17. Will this cake be ok if it is not refrigerated overnight? I plan to make it early in the morning and keep it in the frig until around 8 at night thank you

    It looks yummy and can’t wait to make it,

  18. the title drew my attention because i thought it’s a simple & quick recipe; yet the method got me thinking – go for the 7 ingredients easy bake cake is much better than this!

    • I agree that it looks like serious business to do it, but having tasted flourless chocolate cake, I would point out that it’s an entirely different, delicious experience. Like the world’s best brownie, or fudge in cake form!

  19. Hi,
    Just wanted to let you know I am sharing your wonderful recipe tomorrow in my Gluten-Free Recipe RoundUp with a link back to your original post!
    Have a terrific weekend!
