How to make the best and perfect homemade chocolate fondant cake recipe with an ultra-fudgy and molten center. This recipe is absolutely delicious made with brown sugar which gives it a delicious flavor and salted caramel sauce for an incredible taste.
The chocolate fondant cake is a classic French recipe of chocolate cake (moelleux au chocolat) with an ultra-melting and very chocolatey texture. But this recipe is one of the many variations also called " Fondant Baulois " which comes from the Atlantic Loire region in France.
This chocolate cake is a recipe that we love to make again and again because it is so simple and quick to make for any last-minute occasion.
This chocolate fondant recipe is very similar to my flourless chocolate cake recipe, with its crunchy meringue crust and ultra-creamy texture that is close to a molten chocolate lava cake.
Why we love this recipe
The particularity of this recipe is that it is made with dark chocolate and without cocoa powder to which we add in addition brown cane sugar in combination with salted caramel which gives it this irresistible caramelized flavor and taste.
Baking at a very gentle temperature gives this chocolate fondant recipe an incredibly melt-in-your-mouth, half-baked, creamy texture and if you have time to let it sit overnight in the fridge it is even better the next day.
This chocolate cake makes the happiness of all chocolate lovers enjoy with whipped cream or a scoop of vanilla ice cream and you will have a perfectly decadent dessert to treat your family.

Melt the chocolate
- Place the chopped dark chocolate in a bowl with the cubed butter pieces.
- Heat in a double boiler or in the microwave until the melted chocolate mixture is smooth and free of lumps.
- Add the salted caramel and mix with a spatula or whisk until the mixture is smooth.
Add the eggs and sugar
- In a large bowl, place the brown sugar with the eggs and vanilla extract.
- Mix with an electric mixer or in your stand mixer with the whisk attachment for about 3 minutes on medium speed until the mixture doubles in volume and turns white.
