Grease and line a 24cm (base measurement) cake tin (use a ruler to ensure it is 24cm wide)
Heat oven to 150 degrees fan forced and place rack into middle of oven
Wait 10 minutes to allow oven to heat up, then start to make cake
Place all the ingredients into TM bowl in the order listed … the bowl will look really full but don’t worry … it will all come together when you blend it
Mix 10 seconds / speed 5, scrape down sides and mix again 10 seconds / speed 5
Check and if necessary remix another 2 seconds / speed 5 to fully incorporate
Pour batter into tin, level the top, and bake for 1-1/2 hours until cake skewer inserted into centre comes out clean
Cool in tin for 15 minutes before turning out onto cake rack to cool
Remove tin but leave baking paper on while cooling to stop cake from drying out around edges (it will take a while to cool before icing)
Spread with chocolate ganache and decorate as desired
