Why did another girl who my boyfriend works with make him a cake for his birthday?

You're suspicious of the motivation. I have been in work places where it was customary to buy a cake and some did bake other things then cake. But nobody baked the cake. Was the cake shared or just for him?
I think you are more justified if there is no work cake culture and even more if it was a you only cake.
You might need to learn to bake with this level of competition!
Cause it's his birthday
I mean I don’t know about other girls but…if I made a cake for a man…that means he’s the love of my life. Lol.
Maybe it’s just me, but I wouldn’t make cake for some random guy I didn’t have deep feelings for.
But.. there are some girls who are super nice and naturally like to cater to people’s needs. So it totally depends on the girl’s personality.

Because she is a much better woman than you are.
You’ll have to talk to the boyfriend and talk to the girl
Because she's a nice person.
Why does it matter?
Maybe being nice. Or might have thing for him
