Ingredients
Directions
Place butter in a mixing bowl and work with a spoon until soft.
Add sugar and beat until creamy.
Stir in the milk or other liquid.
Add the beaten eggs.
Gradually mix in the flour and spices.
Bake one cookie to test the dough.
If the cookie is too thick, add 1 tablespoon of milk and a little more flour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Softened butter creams with sugar to give the cookies their rich, tender body.
- Sugar
- Sugar beaten into butter adds sweetness and helps the dough brown as it bakes.
- Eggs
- Beaten eggs bind the dough and add structure and moisture to the cookies.
- Flour
- Flour provides the structure that holds the cookies together as they set.
The step that matters
Testing the dough with one cookie. Flour and liquid amounts can shift the dough's thickness, so a test bake shows whether the cookies will spread or stay too thick before the full batch is baked.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
