When I was growing up, our cakes came from the supermarket. I would like to make my DD’s birthday cake but not sure how to go about it. I have a bit of baking experience but fairy cakes and cakes for tea (in bread tin) I have a food mixer. I’ve never made a round cake before. I look at all these cakes with elaborate decorations and would like to achieve that one day. Any tips on how I should approach this?
