Carrot cake is such a popular classic that everyone loves. This traybake version is really simple to make and has a lovely orange twist, with subtle flecks of orange zest in the cake itself and a beautifully sweet orange icing drizzle. This gluten free carrot cake is so moist, the beauty of it being a cake that uses oil. Added advantage is it is naturally dairy free too! It always freezes really well if you want to keep some in the freezer for a later date!
