Buttercream vs Fondant Wedding Cakes

When choosing the type of wedding cake you want, one of the first things you’ll need to decide is whether you’re a buttercream or fondant kinda person.

Now if you’re sat there confused because you thought there was just one type of cake- the delicious kind- then allow me to enlighten you.

I’m talking about frosting, icing, covering, decoration, whatever you call it, it’s the stuff that covers your cake and gives it a certain look and flavour. Buttercream is a combination of butter and sugar whipped together to make it smooth and spreadable, whereas fondant is a combination of powdered sugar, water and glycerine to make a paste that can be rolled thinly.

Buttercream versus Fondant Wedding Cakes

There was a time when hard-setting royal icing was the only decorative option when it came to your wedding cake, but thankfully rock hard slabs of hardened sugar have fallen out of favour and your guests can hold onto their teeth a little longer.

Chocolate ganache and naked are also modern cake finishes to choose from, but today I’m going to look at Mr and Mrs popular. Ever since Americans started decorating cakes with them, this duo has been battling it out around the world because they each have their own merits when it comes to decorating cakes:

White Fondant Wedding Cake

  • Super smooth and silky finish thanks to rolling it out thinly
  • Soft and chewy to eat, even after a few days
  • Brilliant white colour for classic wedding cakes or can be coloured very vividly
  • Great blank canvas to decorate in different ways
  • Seals in moisture by acting like an air tight container


  • Super sweet, you can’t escape that it’s nearly 100% sugar
  • Artificial smell and flavour that can overpower the cake
  • Needs a skilled baker to carefully handle otherwise it looks terrible
  • Heavy and weighs down light cakes, limiting your choices to denser recipes

Rose Wedding Cake

  • Delicious and creamy, the butter mellows out the sweetness
  • Can be flavoured by almost anything to enhance instead of fight the cake flavour
  • Not too sweet, especially a variety like meringue buttercream which has less sugar
  • Lightweight so can be slathered on any cake
  • Can be coloured with food colouring paste
  • Can also be piped for texture and different effects


  • Melts under high temperatures, so not great for Summer marquee weddings
  • Can look messy if it’s not done properly or rushed
  • Slightly restricted by the range of colours as it’s hard to get very rich shades like you can with fondant

So whether you go for buttercream or fondant on your wedding cake, it really comes down to the look you’re wanting to achieve and your personal preference in terms of flavour/texture. There was a time when buttercream just meant rustic style, but techniques have progressed so much now that many pro decorators can create a super smooth finish as if it is fondant. That’s the joy of getting married these days, you have a huge variety of things to choose from, whether you borrow from the tradition of royal icing or go for a modern naked cake- the choice is yours!

Personally l can not stand fondant. It’s very chewy and rubbery in the mouth. A good cake shouldn’t be too sweet or have a rubber like cover. It does feel like cheating just rolling fondant and covering the cake with it. Baking is supposed to be fun and at the end of all the fun you should create a good cake that taste and looks good.

I came to google to find out the difference between fondant and buttercream because I had no idea…pretty much know nothing about cakes but I loved this article. Very useful.

I have recently just started a wedding cake service company and came across this article.

Really appreciate you taking the time to educate us on this and i just wanted to say that this is so true. I find that that i love crisp, traditional, sharp finish of fondant cakes but i love the taste of a buttercream finished cake. At the end of the day no matter what the cake looks like, you’d have to agree that fondant will always taste like fondant right? Like you said it comes down to what you want to achieve with your wedding cake.

I always love the finished look of cakes covered in fondant but buttercream cakes are always more lustrous.
