ORANGE CHOCOLATE ICING RECIPES

Steps:

• Preheat the oven to 190C/170C Fan/Gas 5. Grease and line two 20cm/8in loose-based sandwich tins with baking paper.
• Mix 50g/1¾oz of the cocoa powder with the just-boiled water to make a smooth, thick paste. Stir in 2 tablespoons orange juice.
• In a food processor or freestanding mixer, add the butter, sugar, eggs, flour, baking powder, remaining cocoa powder, orange zest and the cocoa paste and pulse or beat until well combined, thick and creamy. Do not over-blend or the cake will be tough rather than light. Spoon the mixture evenly into the prepared tins and smooth the surface. Bake on the same shelf in the centre of the oven for about 25 minutes, or until well risen and just beginning to shrink back from the sides of the tin.
• Remove the tins from the oven and leave to cool for 5 minutes before turning out on to a wire rack. Peel off the baking paper and leave to cool completely.
• To make the candied orange zest, use a vegetable peeler to peel long, wide strips off the half orange, avoiding the white pith. Cut the zest into long thin matchsticks and place in a small saucepan with the sugar and 50ml/2fl oz water. Bring to a simmer and cook for about 5 minutes, or until the zest is softened and the sugar syrup is well reduced and lightly coating the zest.
• Line a small tray or plate with baking paper and use a fork to lift the orange zest from the syrup and drop onto the paper, keeping the strands separated. Leave to set for at least 1 hour before using to top the cake.
• To make the chocolate icing, gently heat the cream in a medium non-stick saucepan until hot but not quite simmering, stirring occasionally, then pour over the chocolate pieces. Stir once and leave to stand for 5 minutes. Stir the melted chocolate into the cream just enough to combine – don’t over-stir or the mixture could become oily. Leave to cool for 5 minutes.
• Place one of the sponges on a wire rack over a large plate or tray (to catch any excess icing so it can be reused). Spread a quarter of the chocolate icing thickly over the surface and top with the second sponge. Mix a tablespoon of the milk with another quarter of the chocolate icing (about 135g/5oz) in a small bowl until smooth. Using a palette knife, spread the whole cake thinly with the thinned chocolate icing, filling in the areas where the two cakes meet. Place in the fridge for about 40 minutes to set. (This layer will help the rest of the icing cover the cake more smoothly and doesn’t need to be perfectly neat.)
• Once the first layer of icing has set, stir the remaining 2 tbsp milk into the remaining chocolate icing, until smooth and shiny. Spread the icing all over the top of the cake and down the sides as smoothly as possible using a palette knife. Leave for 2–3 hours to set and then carefully transfer to a cake stand or plate and top with the candied orange zest. (You can also leave it to cool a little and then create a swirly rather than a smooth topping on the cake.)

Steps:

• Preheat the oven to 180ºC/fan160°C/gas 4. Grease 2 x 20cm round sandwich tins and line the bases with baking paper. To make the sponges, measure the cocoa and boiling water into a large bowl and mix to a paste. Add the remaining ingredients and beat again until combined. (You can use a food processor for this but be careful not to overmix.)
• Divide the sponge mixture evenly between the prepared tins. Bake in the preheated oven for about 20-25 minutes until the sponges are well risen and shrinking away from the sides of the tin. Remove the sponges from the oven, turn out of their tins onto a cooling rack and leave to cool completely.
• For the icing and filling, put the chocolate and cream in a bowl, Then stand over a pan of simmering water for 10 minutes until melted (don’t let the bowl touch the water), stirring from time to time. Set aside to cool until it thickens to a spreadable consistency.
• To finish, spread the tops of both sponges with the apricot jam. Spread the top of one sponge with half the icing and put the other sponge on top. Cover the top of the cake with the remainder of the icing, then, with a small palette knife, make large S shapes in the icing to give a swirl effect. Scatter the top liberally with the chocolate curls (see our /how-to-make-chocolate-curls-video/how to make chocolate curls video) and enjoy!
