This flourless chocolate cake is baked with olive oil to create a really rich flavor and texture. It’s subtle, but pairs so well with the bittersweet chocolate in this cake. And because it’s flourless and sans butter, this cake is completely gluten free and dairy free. Not to mention how quick and easy it is to make! It’s ready to eat in under an hour, served warm with ice cream on top.
How does flourless cake hold together?
Since this cake contains zero flour, you might be wondering how it’s able to hold its shape and not melt everywhere.
Flourless cake gets is structure for two main ingredients: chocolate and eggs. The eggs help bind the entire cake together in two ways. One, the yolks add richness and help thicken the chocolate. Since the chocolate makes up a majority of the batter, the egg yolks help stabilize the cake.
Next are the egg whites. These are whipped into stiff peaks then folded into the batter. This not only helps hold the cake together, but also provides some lift to an otherwise super dense cake. In the end you’re left with a very stable cake that’s easy to slice and serve!
Tips for making flourless cake
The entire process takes about 20 minutes so this cake comes together super quick! There are two major steps that go into making it; the chocolate and the meringue. Here’s what you need to know in order to bake a fudgy flourless chocolate cake:
- Cool the chocolate – The recipe starts by melting the chocolate and olive oil together. Once melted and smooth, allow it to cool before mixing in the egg yolks. If the chocolate is too hot, it will scramble the eggs.
- Clean bowl – Make sure the bowl used to whip the meringue is completely clean and dry. Water or crumbs can prevent the meringue from forming.
- Slowly mix in sugar – When the meringue starts to turn opaque, the sugar is mixed in. Instead of dumping it in all at once, slowly pour it in as the meringue whips. This will prevent the meringue from deflating.
- Gently fold – Take your time when combining the chocolate and meringue. Use a rubber spatula to slowly fold the two together. To fold, run the spatula around the bowl and through the batter, scooping up and underneath the batter. Continue to do this until it’s fully combined. If you fold too vigorously, the cake will lose its structure.
- Coat the pan – Really make sure to spray every inch of the baking pan. If the sides stick, the cake will be difficult to remove.

How to bake flourless chocolate cake
I’ve found the best and easiest way to bake this cake is by using a springform pan. For easy release, spray the entire inside of the pan with non stick spray.
Remove the ring and place a sheet of parchment paper on the plate, sticking it to the nonstick spray. Firmly clamp the ring back onto the bottom plate to lock in the parchment paper. This makes it much easier to lift out the cake after it’s done baking.
The cake bakes at 350F for 20-25 minutes. When it’s ready, there should be very small cracks all around the edges and it should be evenly puffed in the center. Give the pan and nudge and it should jiggle a bit – that’s how you know it’s done.
Remove the cake from the oven and leave it at room temperature for about 30-45 minutes. During this time the cake will crack and deflate which is what we want! This creates a dense and fudgy consistency in the center.
Let it cool further in the fridge, until the cake is no longer warm, and it’s ready to slice and enjoy.
The importance of quality ingredients
Since this cake is so simple, there’s no hiding behind cheap chocolate. Try to use really good quality chocolate (Ghirardelli is a great option) and avoid using chocolate chips. Chocolate chips are often processed differently to prevent them from melting too quickly. For this cake, use baking squares to ensure a super smooth batter.
The same goes for olive oil. There are SO many options out there, but try to opt for a quality extra virgin olive oil. You’d be surprised by how much more flavor it has.
Can I use a different kind of chocolate?
Bittersweet chocolate is definitely best here. It creates a really deep and rich flavor that pairs so well with the olive oil. If you don’t have any on hand, semisweet is your next best option.
What can I use besides olive oil?
If you’re a little hesitant about baking with olive oil (trust me, it’s delicious), you can also use melted butter, melted coconut oil, or any milk flavored oil.
What to serve with flourless chocolate cake
The cake alone is like biting into a piece of dark chocolate. It’s rich but not too sweet. This basically leaves the cake as a blank slate for you to add your favorite sweet toppings!
I find that a dusting of powdered sugar completely transforms the flavor. The sweetness helps bring out the dark chocolate even more. But to take it a step further, I recommend serving up each slice with a nice scoop of ice cream. Any flavor would work here.
Another option, or addition to my last recommendation, would be to make some salted caramel to drizzle on top. I have my recipe here which is so easy to make. You could also add chocolate ganache or fresh berries on top.
How to store flourless olive oil chocolate cake
To be honest, this cake does not stick around long! Since it’s not too sweet, you’ll keep going back for more slices. But if you have any leftovers, it’s best to keep it in an air tight container in the fridge. It will keep there for up to 5 days.
When you want a slice, you can either eat it chilled or warm it up in the microwave for a couple seconds. It’s still delicious either way!
