Flourless Chocolate Cake with Chocolate Ganache

A chocolate lover’s dream, this flourless chocolate cake with chocolate ganache may be my all time favorite dessert. A chocolate dessert that will satisfy both traditional and gluten free requests. Instant Coffee is a secret ingredient that magically makes the chocolate even more decadent! Serve with a scoop of vanilla ice cream on top if you wish.

 Flourless chocolate cake with ganache is a gluten free dessert that falls under the category of “this is so good why do we have to say it is gluten free?”. So many gluten free desserts are looked down on as if they are not as good as their gluten-laden counterparts– an opinion I hope to diffuse.
This flourless chocolate cake with chocolate ganache is a dense, fudgy, rich chocolate cake. Make slices smaller than normal because a little of this decadent dessert goes a long way.

My introduction to gluten free flourless chocolate cake came a few years ago when my sweet friends treated me to a birthday lunch and there was a delicious slice of flourless chocolate cake to finish off the meal.

It had never occurred to me to bake a flourless cake. To me, the “less” in flourLESS must have meant that something was missing. Taste, structure, familiarity– something had to be wrong with that type of cake. Well I was certainly wrong about that!

Flourless chocolate cake with ganache is a chocolate cake with a thick, chocolate glaze. It’s easy to make, too. Adding the instant coffee granules deepens the chocolate flavor in the same way that including vanilla extract bumps up the intensity of the chocolate. You could omit the coffee if you don’t have it on hand.

Flourless Chocolate Cake for Holiday Celebrations

A friend of mine serves a Passover flourless chocolate cake at her feast. She makes multiple cakes ahead of time and is ready to delight her guests. This cake is an excellent choice of a make ahead dessert for Passover or for most any other occasion.

One year I baked along with her and it was a true assembly line of cake making. She had the process of making this Passover dessert to a science! 

What is ganache?

Want to take this cake up a level? A chocolate ganache recipe is a quick and easy topping. Ganache is a fancy word for a simple process of combining melted chocolate with cream.

When the two are mixed together a beautiful, glossy, pour-able chocolate topping is created. As the chocolate layer comes to room temperature it will solidify and make a decadent layer on this cake.

Adding a chocolate ganache on top hides any imperfections and makes this dessert something special.

Freezing the cake is also an option– both the cake and ganache freeze very well. I like to slice the cake and freeze it in small portions so that I only eat one slice at a time.

Does Ganache need to be refrigerated?

Even though you’ll read in cook books that chocolate ganache can remain at room temperature for up to two days, I’d recommend being safe and refrigerating the ganache covered cake. 

Ganache, after all is loaded with dairy and although it is heated through when combined with the melted chocolate, you have not cooked the dairy. When in doubt, refrigerate.

Prep Time 10 minutes
Cook Time 30 minutes
Total Time 40 minutes


For the cake:

  • 8 ounces bittersweet chocolate chips
  • 1 cup (2 sticks) for the cake, plus 1 tsp butter for greasing the pan
  • 1 cup sugar
  • 4 eggs
  • 1 cup unsweetened cocoa powder
  • 1 tsp instant coffee granules
  • 1 teaspoon vanilla extract (be sure to choose gluten free vanilla if you want to make the cake Gluten-Free)

For the ganache:

  • 4 ounces chocolate (either chips or from a bar of chocolate, chopped into pieces)
  • 8 ounces heavy whipping cream


  1. Preheat the oven to 350 degrees F.
  2. Grease a 9 inch springform pan with butter. Line the bottom of the pan with parchment. Butter the parchment as well.
  3. Melt 8 ounces of chocolate and the butter in the microwave or over a double boiler.
  4. Add the sugar, eggs, cocoa powder, instant coffee granules, and vanilla extract. Beat well until thoroughly mixed.
  5. Pour into the prepared pan and bake for 30 minutes. Let the cake cool completely before adding the ganache.
  6. For the ganache: Heat the cream on the stovetop or in the microwave (not to boiling, just to a very warm temperature). Add the heated cream to the chocolate chips and let sit for ten minutes. Stir with a whisk until smooth and shiny. Remove the cake from the springform pan and pour the chocolate ganache onto the cake. Let the ganache harden at room temperature.
  7. Store the cake in the refrigerator or freezer if not serving that day.


Refrigerate this cake until ready for serving.

This looks amazing! I’m going to make it this week for my BFs bday. If I’m making it with an 8” pan would I need to cook it for a little longer in the oven as it would be a little thicker?

Because of my work schedule, I will be baking this on a Thursday for a Saturday party. Should I refrigerate it or freeze it? Or just buy a cake?!

This cake will keep well in the refrigerator for a few days. Just let it sit at room temperature for 30-60 minutes before serving. It is also a great cake to freeze (even with the ganache layer on top) then defrost the day you need it. I freeze left overs already sliced so that I can take single servings out of the freezer to enjoy for myself!

I love flourless cakes and frankly anything chocolate. And this is the season of flourless cakes and I need to get to work I do one similar to this but maybe I'll have to try this version. I'm drooling!
