Chock Full O’Hazelnuts Cake Recipe

Chock Full O' Hazelnuts Cake
  • Save

Ok, this cake is not really chock full o’ hazelnuts, but it is full of hazelnut flavor! I had this idea of hazelnut flavored chocolate cake frosted with hazelnut buttercream, but when my local grocery store didn’t have any hazelnut flavoring, I opted to try using some hazelnut flavored instant coffee in the cake instead.

Chocolate batter with hazelnut instant coffee for flavoring. It sounded like a good idea to me. Then another idea came to mind. Why not add some Nutella on the cake? Why you ask, because, there aren’t quite enough calories in this cake yet, 🙄. What else has the most unbelievable hazelnut flavor? Why Ferrero Rocher chocolates, of course!! Oh yes, that’s right the light, crispy, delicious and most decadent taste of hazelnuts to top off this cake. I guess I was feeling a little nutty today…hazelnutty that is!
