Why it works: Butter and peanut match in chemistry and in kitchens. They rank in the top 8% of all ingredient pairs, and 1,621 recipes mention both. Both carry trans-2-decenal, which smells waxy, orange. The science ↓
The recipe
Ingredients
Contains: egg, milk, wheat, peanut (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Make the dough
In a bowl beat butter and peanut butter with an electric mixer on medium to high speed for 30 seconds.
Beat in brown sugar, granulated sugar, egg, and vanilla.
Beat in the flour on low speed.
Spread dough evenly in an ungreased 12- or 13-inch pizza pan.
Bake and top
Bake in a 350 degree F oven for 15 to 18 minutes or until golden.
Remove from oven and sprinkle with chocolate and peanut butter pieces.
Let stand for 1 to 2 minutes or until softened.
With spatula, spread melted pieces over crust.
Top with marshmallows, peanuts, and miniature candy pieces.
Bake about 5 minutes more or until marshmallows are golden.
Cool
Cool pan on wire rack.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, helping the dough bake tender and flavorful.
- Peanut butter
- Adds peanut flavor and fat, contributing to the dough's soft, tender texture.
- Brown sugar
- Adds sweetness and moisture, and helps the crust brown.
- Egg
- Binds the dough and adds structure as it sets in the oven.
- All-purpose flour
- Provides the structure that holds the dough together as it bakes.
- Marshmallows
- Soften and turn golden on top, adding sweetness and chewy texture.
The step that matters
Bake until golden before topping. Partially baking the crust sets its structure so it can support the toppings. Underbaked dough stays soft and can sink or turn gummy under the melted chips and marshmallows.
