A Thoughtful Treat for a Kind Neighbor During Ramadan

Assalamu alaikum! My neighbor was kind enough to lend me a tool recently, and I'd like to return it with a homemade treat as a thank you. Since I noticed they have decorations up for Ramadan, I want to make sure anything I prepare follows Halal guidelines, just in case they choose to enjoy it. Does anyone have any simple and delicious recipes you'd recommend? Jazakallahu khayran for your help!
