Why it works: Cinnamon and vanilla match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 5,287 recipes. Both carry 4-methoxybenzaldehyde, which smells sweet, anise. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Oat bran: Forms the bulk of the batter and gives the muffins a tender, hearty crumb.
Egg substitute or eggs: Binds the batter and provides structure as the muffins set in the oven.
Yogurt: Adds moisture and a slight tang, keeping the muffins tender.
Baking powder: Releases gas in the batter to lift and rise the muffins.
Brown sugar: Adds sweetness and a molasses flavor, and helps browning and moisture.
Apples: Add moisture and natural sweetness, with pockets of fruit throughout the muffins.

The step that matters

Stirring the wet and dry mixtures together. Mixing only until combined keeps the batter tender; overmixing develops gluten-like strands in wheat flours and can make muffins tough. Oat bran has little gluten, but overworking still dries and toughens the crumb.

Swap the walnut

The recipe marks walnut as optional. How well each one fits the dish's main ingredients (cinnamon, sugar, vanilla, apple, egg):
