FOR THE CHOCOLATE FUDGE FROSTING:
TO DECORATE:
Method
- 1. For the cake, pre-heat oven to 170°C / 150°C fan assisted then grease and line a 23x30cm (9x13inch) cake tin with parchment paper.
- 2. Whisk together the dry ingredients in a large bowl or bowl of your stand mixer.
- 3. Add the remaining sponge ingredients and mix just until the batter is smooth and uniform in colour, scraping down the sides of the bowl as needed.
- 4. Pour batter into the prepared cake tin then spread and smooth the top with a spatula.
- 5. Bake until a toothpick inserted in the centre comes out clean, about 32-37 minutes. Place on a wire cooling rack and leave to cool completely in the tin before decorating.
- 6. Do not start on the fudge frosting until the sponge is cool as the frosting needs to be spread while still warm.
- 7. To make the fudge frosting, place all the ingredients into a medium sized saucepan over low heat, stirring until the chocolate and butter has melted.
- 8. Remove from heat and beat with an electric mixer, starting on a low speed then slowly working up to a medium speed, until the fudge frosting starts to cool and thickens to a spreadable consistency that just holds its shape. This can take up to 10 minutes. Tip: To speed up the process, you can transfer the hot fudge frosting into another heat proof dish so that you’re not mixing in the hot saucepan. Tip: For the consistency, rather have the fudge frosting a little too soft and warm than hard and cooled, as it will cool fast and crust over very quickly when you start to spread it on the cake.
- 9. To decorate your cake, spoon the fudge frosting on top of the cooled sponge, then using the back of a spoon or small spatula, spread it evenly over the top of the cake, then create lovely swirls in the frosting. Tip: If your frosting was still a little too warm, just keep creating swirls as this will help it to cool until you get the pattern you like that holds.
- 10. Immediately decorate with Smarties and sprinkles as the frosting will start to crust over almost immediately.
- 11. Use a sharp knife to cut into 5x4 for 20 portions, or 6x4 for 24 portions.
- 12. Store in an airtight container at room temperature for up to 3 days.
