Why it works: Butter and cream match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and 41,494 recipes mention both. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
The recipe
Ingredients
Contains: milk, wheat, tree nuts (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Make the base
In a large bowl, combine together 2 cups of flour, oats, brown sugar, baking soda and salt.
Add butter and stir until everything is moistened.
Reserve 1 cup crumb mixture.
Press the remaining into the bottom of an ungreased 13 X 9 inch baking pan.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Forms the structure of the crumb base and binds the caramel mixture.
- Butter or margarine
- Adds fat and moisture so the dry crumb mixture holds together and browns.
- Brown sugar
- Adds sweetness and moisture, and helps the crumb brown.
- Baking soda
- Helps the crumb rise slightly and brown in the oven.
- Caramel ice cream topping
- Provides a sticky, sweet layer that sets as the bars cool.
The step that matters
Pressing the base into the pan. Pressing the crumb firmly and evenly forms a solid, level base. A loose or uneven base can let the caramel and toppings sink or spill during baking.

Fit is the average pairing score against flour, oats, sugar, butter, chocolate, cream. 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).
