Could a world exist with a distinct line of changing temperatures between the hemispheres?

I'm trying to create a world where there's an equator-like divide running along the axis(?) of the planet and the two hemispheres are perpetually different in terms of temperature. Basically, I want one side of the world to always be warmer than the other side and for the temperature change to be noticeable when crossing over an invisible "divide".

I'm not a physicist and I know very little about astronomy so my thoughts on this might be completely off track, but I was thinking that maybe a circumbinary planet with two stars of differing heat intensities might work? But I think that would affect the changing seasons more so than the relative temperatures of the hemispheres, is that right?

From what I've read, the angle of the planet in relation to the sun is what causes the difference in global temperature, but I don't think that wouldn't create the drastic change that I'm looking for. Any thoughts on how I could make this work?
