Why it works: Olive and walnut match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 2,087 recipes. Both carry 2-undecenal, which smells sweet. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cocoa powder
- Provides the chocolate flavor and deep color of the brownies.
- Olive oil
- Adds fat, giving the brownies a moist, tender crumb.
- Egg substitute
- Binds the batter and helps set the structure as it bakes.
- Sugar
- Sweetens the batter and adds moisture and a chewy texture.
- Rice flour
- Provides the starch and structure that hold the brownies together.
- Walnuts
- Add crunch and a nutty flavor that contrasts with the soft crumb.
The step that matters
Bake until a wooden pick comes out clean. Brownies keep baking from residual heat after they leave the oven. Overbaking dries the crumb, while underbaking leaves the centre wet and unset, so checking at the minimum time matters.
