Carrot cake traybake

Carrot cake is a well-loved classic. There are numerous failsafe recipes to turn to, but the basics are the same: grated carrots, oil, sugar, eggs, flour and spices. I’ve chosen to use a wholemeal flour for the nuttiness it provides and substituted some sugar with a mashed banana. The cream cheese frosting is a classic, but to make this cake a little bit different, I like to add some pecan brittle on top.
