This Diaper Bag Cake Idea is a 9×13 cake x2 and cut long ways in half and stacked making it four alternating layers of chocolate and French vanilla, with buttercream in between the layers, then covered in fondant with handmade fondant elements.
I also used a edible marker to write on the baby products. I did use four dowels in the cake to keep it from sliding.
