How to Stick Fondant to Buttercream

If you’re looking for how to stick the fondant to buttercream, then look no further. Here’s a guide to make it as easy as possible. Let’s take a closer look.

If your decorations were made in advance and have already dried, you don’t need to do this part. However, if you’ve just made your fondant decorations, you’ll want to rub your fingers and hands with a thin layer of cornstarch.

You’ll need a food-grade brush and water. Dip your brush into the water and tap it gently. Brush the side of the fondant decoration you’d like to stick down and then gently press into the buttercream. However, if you’ve only just frosted your cake, you won’t need any water at all, as your fondant will stick with no help whatsoever.

Fondant on Buttercream Problems

When sticking fondant to buttercream you may run into a few challenges. Here are some of the problems you can face and how to fix them.

  • Uneven Buttercream. If your buttercream frosting isn’t smooth before you attach the fondant, you’re likely to see mistakes and imperfections through the fondant; especially if the fondant layer is thin. There’s a simple fix for this. Just ensure your buttercream is as smooth as possible before you stick it to the buttercream. You can use an offset spatula and a turning cake stand.
  • Bulging. No matter how smooth your fondant and buttercream are, bulging can happen. Bulging occurs when air comes between the two and gets trapped inside. Buttercream is more susceptible to bulging than other types of frosting, so this may happen often if not carefully. Before you frost your cake with buttercream, chill it in the fridge so it’s as solid as can be, but still pipeable – this will reduce the chance of bulging.

How to Store a Buttercream Cake With Fondant Decorations

If you’ve made your buttercream cake and decorated it with fondant, you may be wondering how best to store your cake. The simplest way is either wrap in plastic wrap, or in an airtight box/container. The important thing is that no air or moisture can get inside, so tape the box if necessary. Once wrapped, place in a cool, dry area; away from sunlight is best.

Will Fondant Stick to Buttercream?

Of course. If your fondant is fresh, your fondant will stick with no help needed at all. If your buttercream is dried, you’ll need a small amount of water or edible glue to attach the fondant.

How Early Can You Make Fondant Decorations?

Fondant decorations can actually be made well ahead of time; in fact, months in advance! If you’d prefer, you can make them nearer the time, but you need to give them ample time to dry before adding them to your baked goods. The most important thing to do for your fondant decorations is to keep them safe, dry, and away from sunlight.

All you’ll need to store your decorations is a cardboard box and parchment paper. Add your fondant decorations. If you plan to keep them for a while, add uncooked rice or silica gel packets in with the decorations as this will help to keep them fresher for longer.

How Do You Use Edible Glue on Cakes?

To use edible glue, you will need to mix it with a liquid. You can use water, milk, or any other liquid that is safe for consumption. Once the mixture has been made, you will need to apply it to the surface of your cake.

What Type of Buttercream is Best Under Fondant?

Fondant is a sugar-based icing, so it requires a buttercream with some fat. If you want to use a cream cheese frosting, you can make your own by adding some cream cheese and milk to the buttercream.
