This impressive rainbow cake is the perfect way to wow your kids at their next birthday party. It’s deceptively simple to make too – all you need is basic cake ingredients and a rainbow of food colouring!

You will need 6 x 20cm/8in loose bottom sandwich cake tins (approximately 4cm/1½in deep), a 20cm/8in and a 30cm/12in cake board, 2 non-slip cake mats trimmed to about 18cm/7in and 25cm/10in diameter, a turntable, a cake side scraper and 6 medium-sized piping bags.
