Unlike the extensive royal protocol involved in meeting Queen Elizabeth, none will be given to you, if and when you are asked to make her a birthday cake. At least, no guidance was given to Nadiya Hussain in 2016. "It was literally a free for all. I had complete creative control," the celebrity baker told BBC, a bit bewildered. To make things more complicated, Hussain was in Bangladesh filming a documentary while designing' Queen Elizabeth's 90th birthday cake. She would have just four days, after getting back, to bake a birthday cake fit for a royal (via The Sun). As you might imagine, and like Hussain described to British media personality, Jonathon Ross, "it was mayhem."
