No, flourless chocolate cake does not contain gluten. As the name suggests, this type of cake is made without any wheat flour, which is the primary source of gluten in traditional cakes and baked goods. Instead, flourless chocolate cake typically uses alternative ingredients like high-quality bittersweet chocolate, butter, sugar, eggs, and sometimes a small amount of leavening agent, such as baking powder or baking soda.

Because there is no wheat flour or any gluten-containing ingredients used in the recipe, flourless chocolate cake is naturally gluten-free. It is a popular dessert option for individuals with Celiac disease or gluten sensitivities, providing them with a delicious and safe treat to enjoy without worry.

Using gluten-free flour in a cake can alter its texture, taste, and structure. Gluten, a protein present in wheat flour, provides elasticity and structure. Replacing it with gluten-free flour, often made from rice, corn, or tapioca, may result in a crumbly and delicate cake. The absence of gluten can lead to less rising and browning, requiring adjustments in leavening agents and baking times. Additionally, some gluten-free flours have distinct flavours, impacting the cake's taste. To maintain cohesion, recipes often include binding agents like xanthan gum.

While gluten-free cakes can be delicious, it's essential to choose the right flour blend and make appropriate recipe modifications for optimal results.
