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 - 10 inch Bundt cakeIngredients
Contains: egg, milk, 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). Lightly grease a 10 inch Bundt pan with a little of the vegetable oil.
In a large bowl, beat the yellow cake mix, instant banana pudding mix, eggs, water and vegetable oil on medium speed for 2 minutes until smooth.
Fold in the mashed bananas and the chopped walnuts, if using.
Pour the batter into the prepared pan and smooth the top. Bake 50 to 60 minutes, until a toothpick inserted in the thickest part comes out clean and the eggs are fully set.
Cool the cake in the pan for 15 minutes, then turn it out onto a wire rack and let it cool completely.
Whisk the confectioners' sugar, milk and vanilla extract until smooth. Add a splash of water only if the glaze is too thick to pour.
Drizzle the glaze over the cooled cake and let it set for about 15 minutes 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 walnut
The recipe marks walnut as optional. How well each one fits the dish's main ingredients (banana, egg, sugar, milk, vanilla):
- Pecansbetter flavor fit
- Cocoabetter flavor fit
- Almondbetter flavor fit
- Walnutthe original
Fit is the average pairing score against banana, egg, sugar, milk, vanilla. 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).
