I made these for my boyfriend who is obsessed with domino's lava cakes. I thought that this recipe looked close enough and was within my limited skill set. A couple of them came out kind of ugly which was my fault because the filling was too close to the edge and spilled out. I also used a regular size muffin tin. The ones that came out right look really pretty. The flavor was good but i think I'll leave the espresso out next time. Now hopefully these will stand up for a couple more hours in the fridge and reheat in the microwave ok like some of the other reviewers said.
