We had another birthday in the family and an Oreo cake was requested. My newly crowned 6 year old loves chocolate, and is, in fact, the only one in our family of 6 that likes chocolate cake. BUT, when it’s your birthday, you’re king ~ so, Mama made a chocolate cake! He loves all things Oreo, and wanted the pantry staple somehow incorporated into his cake. No prob! Taking some inspiration from all you creative bakers out there I made him a Chocolate cake with layers of Cookies and Cream buttercream. Frosted with vanilla buttercream and some leftover Oreos. It was a very rich cake and only a sliver was enough, but packed into that small sliver of a piece was enough Oreo-goodness to last me til next year!
