I know a lot of businesses like that usually have something familial in it, i.e. Nana's Treats, or Sweets from Home. These let the customers know that you are serving baked goods just like mom made, or grandma made. It brings back positive childhood memories that people never mind returning to through a delicious treat! Is there a special name she goes by, because that could also work, i.e. Dee's Desserts or Yums by Yvonne. Alliteration (Dee's Desserts) is also attractive and memorable. I hope this helps! Have fun, your mom is lucky to have a support like you!
