Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 3% of all ingredient pairs, and 35,031 recipes mention both. Both carry beta-damascenone, which smells apple, rose. The science ↓
The recipe
Ingredients
Contains: egg, milk, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Make the batter
Beat the flour, sugar, cocoa powder, baking powder, salt, buttermilk, shortening, eggs, and vanilla in a large mixing bowl on low speed, scraping sides until blended, then beat on high, scraping sides occasionally for an additional 3 minutes.
Layer and bake
Pour half of the cake batter into a greased and floured 9x13 pan, and bake at 350°F for 15 minutes.
While the cake is baking, melt the caramels and Eagle Brand milk.
Spread the melted caramel mixture over the warm cake.
Pour the remaining cake batter over the caramel mixture.
Bake for an additional 15 minutes, or until done.
Serve
Serve warm with vanilla ice cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the cake together as it bakes.
- Eggs
- Add structure and richness, helping the batter set as it bakes.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Buttermilk
- Adds moisture and tenderness, and its acidity reacts with the leavening.
- Shortening
- Adds fat that tenderizes the crumb and carries flavor.
- Cocoa powder
- Supplies the chocolate flavor and deep color of the cake.
The step that matters
Pour the remaining batter over the caramel mixture. Pouring gently keeps the caramel layer from being pushed into or mixed through the batter, so the two layers stay distinct as the cake bakes.
