How to cover square cakes with fondant. Tutorial

Although lots of people think that covering a cake with fondant is an easy task, getting straight sides and sharp edges needs a particular technique. 

There are lots of methods to get a good finish and all of them are legitimate. You can reach the same destination by different paths, after all. You must follow a set of steps when covering a round cake, but the issue is further complicated if you want to cover square cakes. That’s why I want to show you how I cover square cakes with fondant.

Before covering the square fondant cake: 3 essential points

1. If you’re going to cover a square cake with fondant, make sure that the edges are right-angled and that the sides are perfectly straight. You can use specific tools like a ganache icing smoother or a steel square. Otherwise, the cake won’t be perfect and the covering won’t look good enough.

2. Evaluate the height of the cake. Bear in mind that tall cakes are more complicated to cover with fondant than shorter cakes. This happens because of the excess of fondant that is generated in tall cakes, which we have to reabsorb in order to get a perfect covering. If the cake is really tall, don’t stretch the fondant too thin. Don’t worry about the excess thickness, the fondant will be getting thinner as you smooth it. If it’s too thin from the beginning, it will break.

3. Choose a good fondant. I always use Renshaw Extra, because it’s great to work with. It’s elastic, firm and it never breaks.

15 steps for covering a square cake with fondant

1. In order to show you how to cover a square cake, I’ve chosen a tall dummy. It’s important to extend a great amount of fondant. I used 750gr of fondant. Bear in mind that you must stretch a big sheet of fondant so that it’s easier to handle. Before stretching it, give it a square shape.

2. Start stretching the fondant. Sprinkle a bit of icing sugar so that it doesn’t get stuck to your working surface. It’s important to keep checking it’s not stuck to the surface. Remember that the fondant needs to have the same shape as the cake or the dummy, so keep checking it as you stretch it.

3. A good trick for keeping the necessary shape of the fondant is to stretch in one direction, rotate it 45º and stretch again. And so on, until you get a big square. Measure the sides of the dummy from end to end to obtain the correct measurements of fondant that you need.

4. Place the cake on a swivel base and use a brush to wet the whole surface of the dummy. Be careful not to soak it, because the fondant will slip and will get very sticky.

5. Take the stretched fondant with both hands and carefully place it on the centre of the cake.

6. The first thing you should do now is to fix the corners quickly. When we cover tall cakes, we have a lot of fondant hanging and the corners hold a great amount of weight. If we don’t act fast, the corners will crack. The priority is to stick the fondant to the corners and the upper edges.

7. Once you’ve glued the top, you should glue the fondant to the sides. That way you’ll take the excess fondant through the centre of each side.

8. Repeat the operation until fixing the fondant on all sides. Don’t worry if you have excess fondant in the centre.

9. Start to remove the excess fondant through the centre. Open the wrinkles and slightly press the fondant downwards in order to smooth it.

10. Work each side. Don’t start with the next side until you’re done with the previous side. Finish removing the wrinkles downwards until the end of the dummy.

11. Once you’re done removing the wrinkles, take two fondant smoothers and start to smooth all sides. Be careful not to press too much.

12. Cut the excess fondant from the base and keep it in a plastic bag. Close it right, getting the air out.

13. Take two fondant smoothers to get perfect edges. Place them near the edge and press slightly until the fondant creates a right angle. Unlike in round cakes, you should work all edges.

14. Press the lower edges with a fondant smoother. Repeat this step until the fondant gets really thin on the base. That way, you won’t create any marks when you cut it.

15. Cut the excess fondant with cutter or an X-acto knife. Remove the excess and keep it in the plastic bag you used earlier.

A tip for covering a cake with fondant

If you’re covering a real cake with fondant, the excess fondant may contain cake or chocolate scraps. Be careful not to keep it with the rest of extra fondant, as it may get dirty and change colour, apart from getting damaged.

Do you think it’s easy to extend the fondant for a square cake?
