Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brownie bar dough
- Forms the brownie base that the topping is layered over.
- Peanut butter and milk chocolate morsels
- Melt from the hot brownie to form a glossy, spreadable peanut butter chocolate layer.
- Chopped peanuts
- Add crunch and roasted nutty flavor to the topping.
The step that matters
Spreading the morsels while they are still soft. The morsels must be melted and shiny before spreading; if spread too early they stay lumpy, and spreading after they set leaves an uneven, streaky topping.
Swap the walnut
How well each one fits the dish's main ingredients (peanut, butter, milk, chocolate):
- Almondfits better

- Walnutthe original
Fit is the average pairing score against peanut, butter, milk, chocolate. Candidates are from the same food group and used in at least 100 recipes.
