Made with layers of rich chocolate cake, creamy hazelnut frosting, and chocolate ganache, this fudgy chocolate hazelnut layer cake is the ultimate treat for any celebration.
Assemble the cake:
Slice the rounded tops of each cake with a serrated bread knife to create flat tops. Place the first cake layer on a plate or cake stand. Spread with chocolate filling, then pipe or spread a layer of frosting on top (save some frosting for the second layer as well). Don’t pipe or spread all the way out to the edge as the weight of the cake will make it spread.
