Rich and fudgy gluten-free flourless chocolate cake (made with hazelnut meal!) with a hint of espresso and a crackling crispy top!
It took me a while to get the proportions of this cake just right but in the end, all the trouble was totally worth it. Straight from the oven, this flourless chocolate espresso cake is light as air and intensely chocolaty with a hint of coffee flavor. That said, this cake has a whole new identity if you serve it chilled. When the cake is cold and the chocolate solidifies it takes on a fudgy truffle-like flavor and consistency. I like to serve and eat this cake both ways, room temperature or chilled. Regardless I always serve it with a shot of espresso on the side!
Hazelnut flour can be hard to find (and expensive!) feel free to substitute almond flour instead.
