Fudge and chocolate ganache icing and fillings for rich chocolate cakes

Chocolate fudge and ganache icing and filling recipes for chocolate cakes add a luscious finishing touch that elevates a good sponge cake into an exciting sponge cake.

Some cakes have their own filling and icing recipes that specifically complement that cake's ingredients, like some fudge cakes, so if they are widely different from the basics shown on this page, then they are worth following.

The chocolate icing, filling and frosting recipes here are all good basic recipes. Simple recipes for creating the perfect icings and fillings for all kinds of chocolate cakes, fairy cakes, cupcakes, gateaux, and speciality chocolate cakes.

Many, like the warmed chocolate ganache recipe, can make the best and most simple chocolate sauces, for ice creams, and hot chocolate puddings. While the chocolate fudge recipe is great with brownies and blondies.

The taste of the finished chocolate recipe, belies the simple recipes you have used. Chocolate icings and fillings are also invaluable for decorating your cakes; making your humble chocolate sponge cake look like a patisserie or dessert star.

Extra rich and creamy icing


  • 125g unsalted butter at room temperature
  • 125g of cream cheese
  • 1 teaspoon of vanilla essence
  • 450g icing sugar, sifted
  • 4 tablespoons cocoa powder, sifted

Place butter, cream cheese and vanilla into mixing bowl and, either using a wooden spoon or an electric mixer, beat until soft and creamy.

Gradually beat in the icing sugar and cocoa to make a thick creamy smooth mixture (on low setting if using electric mixer).

Fudge icing

A rich chocolaty fudge topping for large cakes and loaf cakes.


  • 100g plain chocolate, finely chopped
  • 1 tablespoon golden syrup
  • 25g unsalted butter at room temperature

Melt the chocolate in a heatproof bowl over a pan of simmering water (do not let the water touch the base of the bowl - please have a look at other methods discussed in the cooking tips section).

When gently melted and smooth add the golden syrup and butter. When it's all melted and smooth, let the mixture cool and stir occasionally. When you think it is a good consistency for spreading, use before the mixture sets (if it does, very gently warm).

This is enough to fill and top one sponge cake, or top 12 cupcakes/fairy cakes with the fudge icing mixture.

Light and fluffy butter icing

This is not too rich so it is ideal for children's cakes for a birthday party or a teatime treat.


  • 125g unsalted butter at room temperature
  • 400g icing sugar, sifted
  • 3 tablespoons of cocoa powder, sifted
  • 3-4 tablespoons of milk

Makes enough for one sponge cake or 12 fairy cakes

Put the butter into a bowl and, using a wooden spoon or electric mixer, beat until very soft and creamy.

Gradually beat in the icing sugar, cocoa and milk to make a thick smooth icing. If using an electric mixer, use on slow.

Variations: To make this recipe into a light mocha icing, replace the milk with cold coffee. To make a white vanilla icing, omit the cocoa and beat in one teaspoon of vanilla essence.

Chocolate ganache recipe

This is the smoothest and least sweet chocolate icing to use. It is very versatile as it can also be used warm with ice cream, and is lovely with poached pears.

When chilled it is ideal for an intense chocolate addition to any cakes, gateaux or meringues.

When made using plain chocolate, ganache is made from equal quantities of plain chocolate and double cream. These quantities make enough icing to fill and top one sponge cake. 

  • 115ml of double cream
  • 110g of plain chocolate, finely chopped

Put the cream into a saucepan and bring nearly to the boil, so it is scalding hot. With the finely grated chocolate in a heatproof bowl, pour the hot cream over and leave to allow the chocolate to melt into the hot cream. Gently stir to mix.

Leave it to cool long enough for it to be a nice spreadable consistency.

For a professional quality finish on the ganache - use couverture. This is because you can use a higher proportion of chocolate to cream, because couverture is more viscous than ordinary plain chocolate. In this instance, you can use 200g of couverture to 150ml of double cream. You thereby achieve a more rich and intense chocolate result.

Sour cream filling and icing

This makes a rich and velvety smooth icing that will fill and ice one sponge cake.


  • 180g of good quality milk chocolate, finely chopped
  • 90g plain chocolate, finely chopped
  • 225ml of sour cream

With both chocolates in a heatproof bowl, melt together over a saucepan of simmering water.

When melting nicely, remove from the heat and gently stir until smooth. Add the sour cream and whisk using an electric hand whisk until the mixture becomes thick and glossy.

If a good consistency you can spread straight away. In warm weather you may need to chill slightly to get the mixture thick enough to spread.

Chocolate nut butter

This is lovely with hot pancakes and waffles, or even just on toast.


  • 125g butter at room temperature
  • 10ml of caster sugar
  • 30ml of grated chocolate
  • 30ml of finely chopped walnuts, hazelnuts, or pecan nuts

Beat the butter until light and fluffy, and then add all the remaining ingredients and mix well.

Serves 4.

Here is a recipe for almond praline which is useful for ice creams and chocolate cake recipes such as chocolate praline layer cake

Almond praline recipe


  • 100g granulated sugar
  • 100g shelled unblanched almonds

Oiled marble surface or baking sheet, use an oil with no taste to it

Put the nuts and sugar into a small heavy based saucepan. Set the pan over a very low heat until the sugar starts to melt.

Continue cooking until the sugar caramelizes a deep golden color. The almonds should make a popping sound as they toast.

Quickly pour the praline onto the prepared oiled surface. Spread out and leave to cool.

Break into pieces to feed into a food processor to grind into the required consistency for the recipe or until the texture is as you require for taste.
