Fluffernutter Chocolate Cake

Sometimes cakes don’t work out like you want them to.  But sometimes, they turn out better.

Fluffernutter Chocolate Cake

This cake actually started out as a recipe for “salted caramel fudge cake” but frankly all I got was chocolate cake.  Certainly not enough to stand on its own!  As a result, I did what any normal person would do, went into my freezer for my collection of “extra buttercream” and went to town.

Recipe for Fluffernutter Chocolate Cake

What, not everyone stores “extra buttercream” just because?  I highly recommend it.  Good things happen when you do!  See also: Brownies with White Chocolate Buttercream and Mocha Ganache. Chocolate Dipped Peanut Butter Cookie Sandwiches and Macarons

Anyway, I decided it had been way too long since I made a dessert revolving around chocolate and peanut butter (has it seriously been since July?!).  That is a travesty that needed to be immediately fixed.  And fixed it was.

The result:  I convinced myself that I was slicing the cake for photos and taking a bite for photos… but that bite turned into way more cake than I should be eating these days.  Oh, but in the moment it was so worth it.
