Gifts for two female coworkers

So this is my last week of work before I move out of state, two of my female coworkers (in their late 20s) are throwing me a little potlock and making me homemade food. What is something cheap and platonic between 10 to 20 dollars a piece that I can get them to say thanks.

I was originally going to get a nice meal for everyone but told then unexpected things came up and could no longer do so, they decided to make me something instead. I have a hard time letting others do something nice for me and was insistant on helping out but started thinking that was rude of me so instead I will get them a little gift but unsure what I should get because I don't really buy gifts for people outside of my friends and family.

Sorry that was a long story; I have anxiety and overthink things.
