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 ↓
Triple-chocolate Fudge Brownies
Ingredients
Directions
Prepare
Preheat oven to 350°F.
Butter and flour an 8‑inch square baking pan, knocking out excess flour.
Make the batter
In a heavy 1½‑quart saucepan, melt bittersweet and unsweetened chocolate and butter over low heat, stirring until smooth.
Remove pan from heat.
Cool mixture to lukewarm and whisk in sugar and vanilla.
Add eggs, one at a time, whisking until mixture is glossy and smooth.
Stir in salt and flour just until combined.
Stir in chocolate chips.
Spread batter evenly in pan.
Bake and cool
Bake in middle of oven 25 to 30 minutes, or until a tester comes out with crumbs adhering to it.
Do not over‑bake.
Cool brownies completely in pan on a rack before cutting into 16 squares.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bittersweet chocolate
- Provides the deep chocolate flavor and fudgy body of the brownies.
- Butter
- Adds richness and moisture, helping the brownies stay tender and fudgy.
- Eggs
- Bind the batter and set during baking to give the brownies their structure.
- All-purpose flour
- Provides just enough structure to hold the fudgy batter together.
- Sugar
- Sweetens the batter and contributes to its glossy, smooth texture.
The step that matters
Do not over-bake. Brownies keep baking from residual heat after leaving the oven, and overbaking dries them out and firms the texture, losing the fudgy center. Pulling them when a tester still shows moist crumbs keeps them dense and moist.
