Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Red Velvet Bundt Cake
Ingredients
Directions
Prepare the batter
Preheat oven to 350°F. Grease the bundt pan and set aside.
In a mixing bowl, whisk together flour, baking soda, salt, and cocoa powder.
In another bowl, cream sugar and butter with an electric mixer until pale and fluffy, 4–5 minutes.
Add oil and mix.
Add eggs and yolks, one at a time, mixing after each addition.
Add vanilla, vinegar, and red food coloring.
Add the flour and buttermilk
Add about one‑third of the flour mixture and stir to combine.
Add half of the buttermilk and stir to combine.
Repeat, alternately adding the flour and then buttermilk, ending with flour.
Fold in chocolate chips, if using.
Bake and cool
Pour batter into prepared bundt pan and smooth into an even layer. Bake in preheated oven for 40–55 minutes or until a toothpick inserted into the center comes out clean.
Cool in cake pan for 10 minutes, then invert onto a wire cooling rack to cool completely.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Provides the structure that holds the cake together as it bakes.
- Granulated sugar
- Creaming with butter traps air for a light, tender crumb and adds sweetness.
- Unsalted butter
- Adds fat for richness and tenderness, and helps trap air when creamed with sugar.
- Eggs
- Add structure and binding, and their yolks add richness and moisture.
- Buttermilk
- Adds moisture and acidity that tenderizes the crumb and reacts with the leavening.
- Baking soda
- Reacts with the acidic buttermilk and vinegar to produce gas that lifts the cake.
The step that matters
Alternating the flour and buttermilk. Adding the flour in portions and ending with flour keeps the batter emulsified and limits gluten development, so the cake stays tender rather than tough.
