There’s PLENTY of monkeying around with this banana toffee cake! Okay YoYo’s, don’t get me wrong I LOVE making crazy sculpted novelty cakes for you, but there is also something so SUPER fun about stacking up an ooey-gooey mega cake. It’s where I get to play with some of my fave flavors, and present them in a pretty magical way!

Starting with 6lbs of my Ultimate Banana Cake, 2 of my layers get baked up with a crunchy sweet graham cracker crust! Stacked up with lucious Italian Meringue Buttercream, caramelized bananas, dulce de leche, and toffee candies, I’m playing with texture through a banana and plantain chip coating to make this one cake that’s ready to monkey around!
