  • What to do for Mother's Day?

    I completely forgot about Mother's Day which is in 2 days time! I really want to get my mum something really nice. I know she likes handmade presents so I've decided to bake my mum a heart shaped red velvet cake with 1 square shaped cake and 1 circular put together. Only I haven't got a square shaped tin. Is there anything I could use as a substitute?? Also, is there anything else I could make her that is fairly easy? Please no sewing. Or do you think the cake is enough???
