Can you make a cake without flour? Yup, you bet! These cakes are very delicate, so they're often made in springform pans for easy removal. Flourless cakes are often baked in a water bath, too, where the cake pan is set in a larger pan filled halfway with hot water. This insulates the cake and produces a silkier, less porous texture. It also prevents the bottom from burning. Flourless cakes are often very rich because of their high fat content, which is necessary for structure in the absence of flour.
