In a large mixing bowl, add eggs, oil, beer and mix until smooth. Add cake mix and mix and mix until just combined.
Pour batter in two greased/ floured round cake pans (Dimensions: 8x2). Spread evenly with a spatula. Bake at 350 degrees F for about 30 minutes or until an inserted toothpick in the center comes out clean.
Allow the cakes to cool down completely.
While the cakes are baking and cooking, prepare the chocolate frosting, following the recipe above.
Place one cake on a cake board (same size as the cake).
Spread frosting on top of the cake.
Place the other cake on top of the frosting and gently press it to hold it into place.
Ice the entire cake in a thin coating of frosting. This is called a "crumb coat" just to seal the crumbs together. Chill in the fridge for 20 minutes.
While the frosted cake is chilling, prepare the thick ganache by adding equal parts of heavy cream and chocolate chips in a microwave-safe bowl. Heat in the microwave at 30 second increments, mixing often, until smooth and creamy.
Place a cooling rack on a cookie tray. Place the cake on top of the rack. Don't remove its base board. Pour ganache on top of the cake and spread it all around the top and let it drip along the sides. Use a spatula to cover it entirely in a ganache coating.
When ganache is no longer dripping at the bottom, remove it from the rack and place it on a cake stand or serving plate.
Chill in the fridge for 30 minutes.
Decorate with chocolate rolls and sprinkle chocolate curls around the base of the cake. Enjoy!
