I wouldn't have thought so if you're thinking traditional cakes - they're pretty much made of flour for texture, but if you're willing to stretch the definition of 'cake' there are some quite nice foods to be had which are similar - I made some really nice nutty bites which were made of peanut butter, coconut flour, ground almonds a few oats, nuts and seeds. I wish I could tell you the recipe, but I just added stuff I fancied until it looked more or less like biscuit dough.
Cheesecake is possible too, as long as you use a nutty base, not a biscuit one.
