Should I Take Kit-Kat’s on Carry-on Luggage

I’m currently visiting Japan and I want to bring some of the exotic flavored kit-kats here back to Turkey. The thing I’m scared of is them melting in my carry-on bag while I’m returning. I don’t plan to check in any baggage since I don’t have much luggage so I was wondering your opinions on if it would melt as carry-on or not.
