Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Graham cracker crumbs: Form the crumbly base that holds the chocolate layer together.
Butter: Binds the crumbs and adds richness to the base.
Dark chocolate: Provides the chocolate flavour and rich, firm body to the filling.
Cream cheese: Gives the filling its dense, smooth, creamy structure.
Egg: Sets during baking to firm the filling into a sliceable texture.
Heavy cream: Adds moisture and smoothness to the melted chocolate for a silkier filling.

The step that matters

Bake until just set. Cream cheese and egg filling turns grainy, cracked and dry if overbaked, because proteins tighten too far. Pulling it out while the centre still wobbles lets residual heat finish setting it smoothly.
