Why it works: Chocolate and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 10,020 recipes. Both carry sotolon, which smells curry, maple. The science ↓

Ingredients
Directions
Prepare the pan
Heat oven to 350°F.
Line 9-inch square baking pan with foil, extending foil over edges of pan. Grease and flour foil.

Beat in eggs and vanilla until well blended.
Stir together flour, baking soda and salt. Stir into chocolate mixture.
Spread batter into prepared pan.
Bake and top
Bake 15 to 20 minutes or until brownies begin to pull away from sides of pan.
Meanwhile, prepare CLASSIC CARAMEL TOPPING.

Cool completely in pan on wire rack, being careful not to disturb chips while soft.
Cut into bars.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and help give the brownies their set, structure-holding crumb.
- All-purpose flour
- Provides the structure that holds the brownie batter together as it bakes.
- Semi-sweet chocolate chips
- Melted into the batter to add chocolate flavor and fudgy richness; unmelted chips add pockets of chocolate.
- Butter or margarine
- Adds fat for richness and a tender texture in the brownie.
- Sugar
- Sweetens the batter and helps give the brownies a moist, tender crumb.
- Baking soda
- Helps the brownie rise slightly and brown during baking.
The step that matters
Remove brownies from oven and spread topping immediately. The brownies are still hot and soft, so the topping spreads evenly and bonds to the surface; waiting lets the base set and the topping may not spread well.
