Why it works: Banana and vanilla match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 1,430 recipes mention both. Both carry ethyl isobutyrate, which smells fruity, ethereal. The science ↓
The recipe
1 - 9x5 inch loafIngredients
Contains: egg, milk, wheat, tree nuts (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.
Heat the oven to 350°F (175°C). Grease a 9x5 inch loaf pan with a little of the butter.
Beat the remaining butter and the white sugar together until light and creamy, about 2 minutes.
Beat in the eggs one at a time, then add the vanilla extract and the pureed bananas and mix until smooth.
In a separate bowl, whisk together the flour, baking soda, baking powder and kosher salt.
Fold the dry ingredients into the banana mixture just until no dry flour remains. Fold in the chopped macadamia nuts.
Spread the batter evenly in the prepared pan. Bake for 55 to 65 minutes, until a toothpick inserted in the center comes out clean. Tent with foil if the top browns too quickly.
Cool the loaf in the pan for 10 minutes, then turn it out onto a wire rack and cool completely, about 1 hour, before slicing.

Sugar and vanilla share little aroma chemistry, yet 35,031 recipes mention both: they likely work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
Flavor stand-ins for the macadamia nut

Fit is the average pairing score against butter, sugar, egg, banana, vanilla, flour. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
