Avengers - Endgame

I made this cake for a coworker who is leaving our organization. She loves the Avengers and her first name begins with "A," so it all works out nicely.  She loves chocolate and peanut butter so I made a three-layer chocolate cake with vanilla buttercream on the outside and peanut butter frosting for the filling. I hope it's a tasty combination!

Update: The cake tasted fantastic! The peanut butter frosting was light and fluffy and was a great compliment to the chocolate cake.
