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 ↓
Chocolate Brownies, Low Cal
Ingredients
Directions
Make the batter
Place a large heatproof bowl over a pot of hot water.
Melt the chocolate with the water, stirring until smooth.
Remove the bowl from heat and let the mixture cool slightly.
Whisk in the egg whites and vanilla.
In a separate bowl, stir together the sugar, flour, baking powder, and salt.
Stir the dry mixture into the chocolate batter just until combined.
Bake and finish
Pour the batter into a lightly greased 8-inch square cake pan.
Bake in a 350°F oven for 20 to 25 minutes or until the edges pull away from the pan.
Let the brownies cool on a rack, then dust with icing sugar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chocolate, semisweet
- Provides the main chocolate flavour and a dense, fudgy body when melted into the batter.
- Egg whites
- Add structure and help bind the batter so it sets as it bakes.
- Sugar
- Adds sweetness and contributes to a moist, tender crumb.
- Flour, all-purpose
- Provides structure so the batter sets into a sliceable square.
- Baking powder
- Releases gas during baking to give the brownies a light lift.
The step that matters
Stir the dry mixture in just until combined. Overmixing after adding flour develops gluten, which toughens the brownies and makes them dense and rubbery rather than tender.
