Flourless Chocolate Espresso Cake Recipe. This is the first gluten free cake I have ever made, so this may be an unfair review, but it was quite average in taste. The cake will turn out looking exactly like the picture. It has a fluffy cake-like texture and a deep chocolatey taste. I dolled it up with raspberry's and a chocolate drizzle. It wasn't bad but I've had better flourless chocolate cakes.
