How about a signed photo or movie memorabilia of Benedict Cumberbatch for your mom? Alternatively, you could get her a subscription to a streaming service that has his movies or shows, or even tickets to see a live performance starring him. You could also take her out for a themed brunch or dinner based on one of his movies or characters. Another idea could be a custom-made portrait of your mom and Benedict Cumberbatch together, which she could hang on her wall. I hope this helps!
Or you can get her a star map with the date when she gave birth to you.
