Advice on job

So I work at dominos. Making 8.60 an hour for like 20 hours a week. I don’t make much at all. Well I went to find a new job for more money and hours and I start training Monday. They pay 10 an hour, 50$ every week for good attendance and I get paid time off as well as 100$ sign up bonus (dunkin donuts). I brought it up to my manager that I needed to put my 2 weeks in and she told me she didn’t want me to quit and offered me 12$ an hour and management for 30 hours a week in about a month or so. Idk what to do. Should I stay or should I go to dunkin :/. She also told me if I don’t stay I’m more then welcome to come back when ever I want because I’m a good worker.

I hate dominos lol, but I also love dunkin and I get free coffee 😂. Idk what to do
