Gluten-Free Espresso Chocolate Cake with Chocolate "Buttercream"

First off: HAPPY BIRTHDAY LILY! My sister is a HUGE chocolate cake fan and as far back as I can remember we have had chocolate cake for her birthday! This year, I can't be with her on her birthday (we live in different states) so I'm baking a cake in her honor and sharing it with all of you guys!

This cake is gluten-free, vegan *including the buttercream* and damn delicious! Most gluten-free cakes are very much like cardboard but this one is so yummy it honestly surprises people when I tell them its gluten-free! I took some to work and the big burly dudes I work with had no idea (i'd say thats a good sign!) Let's start baking!
