If the frosting! Of your cupcake! Is equal to or greater in height than the cupcake itself! you made a bad fucking cupcake
We can’t as a society keep supporting pastries that are just edible plates for five inch piles of sugar glue
Frosting is akin to a sauce or seasoning. You use it to add flavor and texture. It should not be the ONLY source of flavor and texture.
Also, some of that flavor should be something other than “SUGAR”, except when we’re talking about donut/pound cake glaze. Sugar glazes like that are intended to add moisture and sweetness and not really anything else. Frosting should have at least a note of another flavor.
