As I mentioned above, I decided to cook my cake in a loaf tin, which meant the cooking time was a little different to that stated on the packet. Mine needed a further 5 minutes before a skewer inserted into the cake came out clean.
It released easily from the tin, and I then left it to cool before cutting a slice.
I have to say the cake was delicious! Moist, fluffy, light and tasty. It was sweet, without being overly sweet, and the cinnamon added a nice flavor.
This is one gf cake mix that I will definitely be using again. The only difficulty I encountered was sticking to just one slice!
