Buttercream Wedding Cake Frequently Asked Questions

What is buttercream frosting?

Buttercream frosting gets its name from—you guessed it—the large amount of butter that goes into creating the mixture. Each cake baker has their own recipe, but in general, buttercream is made by mixing powdered sugar, butter, milk and a hint of vanilla to create a rich, sweetened cream.

Can you add flavors to buttercream frosting?

Cocoa powder, peanut butter, liquor, lemon juice, and other ingredients can all be used to flavor buttercream depending on the recipe. In most cases, adding a flavor will change the color of the buttercream as well, but you can also use food coloring.

Does a buttercream wedding cake need to be refrigerated?

Buttercream is oil-based (hello, butter), so it does need to be refrigerated to prevent the frosting from melting. Bring the cake to room temperature by removing it from the refrigerator about 20-30 minutes before serving. The risk of buttercream melting is more likely in warmer settings, so be sure to ask your cake baker for their specific advice.

How long will a buttercream wedding cake last?

If you're planning to follow the tradition of saving your wedding cake, it's important to properly package and store it. While most buttercream cakes only last a few days in the fridge, you can preserve yours for several months in the freezer by using plastic wrap and an airtight container.

How do you decorate a buttercream wedding cake?

The great thing about buttercream wedding cakes is that they can be as simple or as intricate as you want. Spreading the buttercream onto the cake naturally creates a textured look that your baker can leave as-is or use special tools to smooth out. The buttercream can also be grooved, striped or swirled depending on your preference. Fresh flowers, hand-piped details, fresh fruit, sprinkles and colorful icing are some of the most popular ways to decorate buttercream cakes.
