I wouldn’t even consider using a box mix and always make my cakes from scratch. I have customers who tell me they are disappointed now when they buy a cake from the supermarket because it just doesn’t compare. For me the flavour of the cake is at least, if not more important than the way it looks and I get such a confidence boost every time someone tells me they think my cakes are delicious. However, I have been baking since I was 12 and it has taken me years to find the recipes I can really rely on for the results. There’s a huge amount of trial and error and you eventually develop an intuition for how to make your cake as perfect as you want to be so I can understand someone starting out by using a boxes mix. But, when you get the hang of baking there is so much satisfaction to be gained from making your own cakes.
