Step 3: Frosting and Decorating
Combine the marshmallow fluff, butter, sugar, and vanilla with an electric mixer until the ingredients are evenly dispersed. Smooth the lovely fluff onto the cupcakes.
I made a batch of mini cupcakes along with the larger ones, and instead of decorating them with the caramel or chocolate web, I sprinkled cinnamon on tops. You can always skip the web design, and opt for a dusting of cinnamon, a sprinkle of butterscotch chips, or a simple drizzle of caramel or butterscotch sauce.
To create the web design, draw three circles with the sauce of your choice. Start from the center of the cupcake, and using a toothpick or the edge of a knife, pull out five lines that reach the edge. In between the lines you've just drawn, pull out another line for each space. (See picture for an example).
