Why is buttercream banned in some states?

Buttercream is banned or restricted in some states under Cottage Food Laws because it's considered a "potentially hazardous food" (PHF) due to its dairy, butter, and egg content, which can support rapid bacterial growth at room temperature, posing a food safety risk for home-based businesses. States often prohibit items requiring refrigeration or temperature control, meaning buttercream, cream cheese frosting, or whipped cream are generally disallowed unless modified to be shelf-stable, such as using shortening or specific testing. 

What buttercream do professional bakers use?

Professionals commonly use Swiss Meringue Buttercream (SMBC) and Italian Meringue Buttercream for their smooth, less-sweet, and stable texture, ideal for detailed piping and filling tiered cakes, while also relying on American Buttercream for its classic sweetness and heat stability, especially for simpler decorating tasks like piping flowers. The choice depends on the desired flavor, texture, and application, with meringue-based options offering a silky, less sugary alternative to the dense sweetness of American buttercream, notes The Kitchn, Sugarologie, and The Nifty Baker.
 

What is the difference between frosting and buttercream?

Frosting is a broad category for sweet toppings, while buttercream is a specific, popular type of frosting, distinguished by its rich, buttery base (butter + powdered sugar) that's great for piping and stability; other frostings, like whipped cream or cream cheese frosting, use different bases (heavy cream, cream cheese) for lighter or tangier results, differing in texture, sweetness, and stability. Think of buttercream as a delicious subset of the larger frosting family, ideal for elaborate designs, whereas lighter frostings suit simpler, airier desserts.

Always perform a sniff and taste test for off-smells, mold, or weird textures before eating. 

How long can buttercream frosted cake last in the fridge?

A buttercream cake generally lasts 3 to 5 days in the fridge, though it can stay fresh for up to a week if well-covered, thanks to the high butter content, but it's best served after warming slightly at room temperature to soften the stiffened frosting. For cakes with perishable fillings (like cream cheese, fruit, or custard), refrigeration for 3-4 days is crucial, while American buttercream cakes with no perishable extras can sometimes stay at room temp for a couple of days before refrigerating. 

Should you cover a cake with foil or saran wrap?

For best results, wrap a completely cooled cake in plastic cling film for short-term storage to keep it moist and protect it from odors, then add a layer of foil for extra protection, especially for longer storage or freezing to prevent freezer burn. For freshly baked, warm cakes (not hot), foil helps retain heat and moisture, but let it cool significantly before using cling film.

Refrigeration isn't ideal for texture as it can dry out the cake, so store in an airtight container to prevent this if you must refrigerate.
