Why it works: Peanut and rice match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 670 recipes. Both carry 2-acetyl-1-pyrroline, which smells popcorn, roasted. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Butter or margarine: Adds fat and richness, helping the cookies brown and stay tender.
Peanut butter: Adds fat and peanut flavor, and helps bind the dough.
White rice flour: Provides the main structure in place of wheat flour, which is absent here.
Tapioca flour: Adds starch that helps give chewiness and a softer texture to gluten-free dough.
Egg: Binds the dough and adds structure and moisture.
Baking soda: Reacts with acidity in the dough to produce gas, helping the cookies rise and brown.

The step that matters

Bake until just lightly browned. Gluten-free cookies have no gluten network to hold moisture, so they dry out and turn brittle if overbaked. Pulling them when the edges are just lightly browned keeps them tender, since they keep firming as they cool.
