    Ingredients and substitutions for French Chocolate Cake

    • Dark chocolate: 54% dark chocolate was used thanks to it's overall higher quality. If you prefer, you could replace with milk chocolate in equal measure, though the final result will likely be a lot sweeter.
    • Butter: Unsalted butter was used, though salted butter also works here.
    • Sugar: The best sugar here is superfine or caster which helps dissolve into the eggs and remaining cake batter. You could half and half the sugar with raw sugar or light brown sugar and caster sugar as I do not recommend completely substituting out superfine or caster sugar.
    • Eggs: The eggs help to bind the cake and give us the fudgy final texture.
    • Flour: You donโ€™t need much so this can be substituted with gluten free flour to make this gluten free friendly.

    FAQ's for the best French Chocolate Cake

    Do I need to use dark chocolate in this cake?

    Dark chocolate is superior to milk chocolate as it relies less on dairy and aids in regulating sugar content in baking. Using dark chocolate in baking helps the sugar counteract the chocolate's bitterness, resulting in a more well-rounded flavor.

    Can I make French Chocolate Cake ahead?

    You can! Best served within 2 days of baking, this will last up to 4 days when kept covered in a container.

    Notes

    • Dark chocolate: 54% dark chocolate was used thanks to it's overall higher quality. If you prefer, you could replace with milk chocolate in equal measure, though the final result will likely be a lot sweeter.
    • Sugar: The best sugar here is superfine or caster which helps dissolve into the eggs and remaining cake batter. You could half and half the sugar with raw sugar or light brown sugar and caster sugar as I do not recommend completely substituting out superfine or caster sugar.
    • Springform cake tin: A springform tin makes getting the cake out of the tin easy work! This is best baked in a 20cm or 8 inch tin or better yet a 15cm or 6 inch cake tin for a higher and fudgier cake.
    • You can make this ahead: Best served within 2 days of baking, this will last up to 4 days when kept covered in a container.
