We challenged chefs of three different skill levels - amateur Emily, home cook Gabrielle, and professional chef Penny Stankiewicz from The Institute Of Culinary Education - to make us a celebratory birthday cake.
Once each level of chef had iced up and served their creation, we asked expert food scientist Rose to explain the choices each made along the way - both good and bad.
Which birthday cake are you blowing out the candles on first?
