Chocolate Chip Cookies

Heat oven to 355°F.

Mix flour, salt, and baking soda in a medium bowl.

Mix butter and sugars until blended, then add egg, egg yolk, and vanilla.

Add dry mixture until combined, half at a time.

Stir in chocolate chips.

Scoop out about 2 tablespoons for large cookies and place on cookie sheets.

Bake for 10–13 minutes depending on size; watch for hard edges and a soft, puffy center.
