Quick Answer

To cover a cake with fondant successfully:

2. Apply a crumb coat and chill the cake.

3. Smooth a final layer of buttercream or ganache.

4. Roll fondant to 3–4 mm thickness.

5. Drape the fondant gently over the cake.

6. Smooth the top and sides carefully.

7. Trim away excess fondant.

8. Allow the cake to rest before decorating.

Following these steps helps create a smooth, professional finish that’s perfect for any celebration.

What You’ll Need

Before you begin, gather these essential cake decorating supplies:

• Fully cooled cake layers

• Buttercream or ganache

• Ready-to-roll fondant

• Colour Mill oil-based food colouring (optional)

• Rolling pin

• Cake turntable

• Acrylic scraper

• Palette knife

• Fondant smoother

• Cornflour for dusting

• Sharp knife or pizza cutter

Using high-quality cake decorating tools makes the process easier and helps produce a cleaner, more professional result.

Step 1: Level and Stack Your Cake

Start by trimming the top of each cake layer using a cake leveller or serrated knife. Flat layers create a stable cake and prevent the finished cake from leaning once covered.

Spread an even layer of buttercream or ganache between each layer before stacking. Press gently to remove air pockets without squeezing out the filling.

Expert Tip: Check the cake from eye level before continuing. Even a small lean becomes much more noticeable after applying fondant.

Step 2: Apply a Crumb Coat

A crumb coat is a thin layer of buttercream that traps loose crumbs and creates a clean surface for the final coating.

Using a palette knife, spread a light layer over the entire cake. The finish doesn’t need to be perfect—its purpose is simply to seal the crumbs.

Refrigerate the cake for about 30 minutes until firm.

Skipping this step often results in crumbs showing through the fondant, making the final finish look uneven.

Step 3: Apply the Final Buttercream or Ganache Layer

Once the crumb coat has chilled, apply a thicker, smoother layer of buttercream or ganache.

Rotate the cake on a turntable while holding an acrylic scraper or bench scraper against the sides. This technique creates straight, even edges with minimal effort.

For ultra-sharp corners, many professional cake decorators prefer ganache because it sets firmer than buttercream and provides a stronger foundation.

Allow the cake to chill again before applying fondant.

Step 4: Prepare and Colour the Fondant

If you’re using white fondant, now is the ideal time to add colour.

Knead Colour Mill oil-based food colouring into the fondant gradually until the colour is completely even. Let the fondant rest for a few minutes before kneading once more.

Soft, smooth fondant rolls more evenly and is less likely to crack while covering the cake.

Step 5: Roll Out the Fondant

Lightly dust your work surface with cornflour.

Roll the fondant from the centre outward, rotating it regularly to maintain an even thickness of approximately 3–4 mm.

The sheet should be large enough to cover both the top and sides of the cake with several centimetres of extra overhang.

Avoid rolling the fondant too thin, as it can tear easily during application.

Step 6: Cover the Cake

Carefully lift the rolled fondant using your rolling pin and position it over the centre of the cake.

Smooth the top first before gradually working down the sides using your hands or a fondant smoother.

Rather than pulling the fondant downward, gently ease it into place while smoothing small sections. This helps prevent wrinkles, stretching, and tearing near the base.

Working slowly produces a much cleaner finish than rushing through this step.

Step 7: Smooth and Trim

Once the cake is fully covered, use a fondant smoother in gentle circular motions over both the top and sides.

This removes small air pockets and creates a polished surface.

Trim away the excess fondant at the base using a sharp knife or pizza cutter.

For an elegant finish, consider adding a decorative ribbon, fondant border, or piped buttercream around the base of the cake.

Step 8: Decorate Your Cake

Allow the fondant to rest for 20–30 minutes before adding decorations.

This gives the fondant time to firm slightly, making it easier to apply personalised acrylic cake toppers, cake charms, edible decorations, lustre dust, embossers, or edible prints.

Whether you’re creating a birthday cake, engagement cake, wedding cake, or baby shower centrepiece, thoughtful finishing details help turn your cake into a memorable celebration.

Frequently Asked Questions

1. How thick should fondant be when covering a cake?

For the best results, roll fondant to approximately 3–4 mm thick. This thickness provides enough strength to prevent tearing while still creating a smooth, elegant finish.

2. Should I use buttercream or ganache under fondant?

Both work well. Buttercream is easier for beginners, while ganache creates sharper edges and a firmer surface, making it the preferred choice for professional-looking cakes.

3. Why does my fondant crack while covering the cake?

Fondant usually cracks because it has dried out or has been rolled too thin. Kneading it until soft and rolling it evenly helps prevent cracking.

4. Can I decorate the cake immediately after applying fondant?

It’s best to allow the fondant to rest for 20–30 minutes before adding cake toppers, edible decorations, or embossing details. This helps the surface firm up and reduces the risk of damage.

5. What cake decorating tools do beginners need?

Essential tools include a rolling pin, fondant smoother, cake turntable, palette knife, acrylic scraper, and sharp knife. As your skills grow, you can also add embossers, cake charms, edible prints, and personalised acrylic cake toppers to create more detailed celebration cakes.
