Why it works: Cocoa and vanilla match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and 357 recipes mention both. Both carry sotolon, which smells curry, maple. The science ↓
The recipe
Ingredients
Contains: egg, milk, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare
Preheat the oven to 350°F. Grease a 13×9×2‑inch rectangular pan.
Combine sugar, flour, and xanthan gum in a large mixing bowl. Set aside.
Make the batter
Combine oil, butter, cocoa, and cola in a medium saucepan. Bring the mixture to a boil over medium heat, stirring constantly.
Add the chocolate mixture to the sugar mixture and beat until smooth.
Stir in the marshmallows.
Add the buttermilk, baking soda, eggs, and vanilla; blend well. Pour the batter into the greased pan.
Bake
Bake 40–45 minutes or until a toothpick inserted in the center comes out clean.

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
What each ingredient does
- Eggs
- Bind the batter and add structure as the cake bakes and sets.
- Buttermilk
- Adds moisture and acidity that tenderizes the crumb and reacts with the baking soda.
- Baking soda
- Reacts with the acidic buttermilk to produce gas that helps the cake rise.
- Gluten free flour mix
- Provides the starchy structure that the cake sets around in place of wheat gluten.
- Xanthan gum
- Acts as a binder that gives the gluten-free batter elasticity and holds it together.
- Sugar
- Sweetens the cake and helps keep it moist and tender.
The step that matters
Bring the cola mixture to a boil. Boiling the oil, butter, cocoa and cola together blooms the cocoa and melts the fat so it blends evenly into the batter. Stirring constantly prevents scorching on the bottom of the saucepan.
