Flatirons Soap Works makes bath bomb cupcakes because they are so easy to customize and to personalize. Previously, we frosted our cupcake with whipped soap. This past fall we found bubble frosting. “What is bubble frosting?” you ask. It is solid bubble bath. When using your new FSW cupcake, remove decorations, lift bubble frosting from the cupcake and break frosting into a few pieces. Hold these pieces under the faucet while filling the tub. When the tub is full, drop in your cupcake bath bomb. You will have bubbles AND a great smelling bath bomb and beautifully hued water. We at FSW hope you enjoy your new and improved bath bomb cupcakes!
