Joy of Cooking's Chocolate Chunk cookies

This recipe isn't very different from the Nestle Tollhouse standard chocolate chip cookie recipe. If you check out their the Joy of Cooking's website though, you'll see that this recipe was "tested". Really? Somehow I doubt they tested it at high altitude because they turned out like lumpy chocolate chip pancakes. If you're at high altitude - add 1/2 cup of flour.

Ingredients:

• 2 cups all purpose flour
• 1 1/4 teaspoons baking soda
• 1/4 teaspoon salt
• 3/4 cup unsalted butter, room temperature
• 2/3 cup granulated white sugar
• 2/3 cup firmly packed light brown sugar
• 1 large egg
• 1 large egg yolk
• 1 1/2 teaspoons pure vanilla extract
• 1 1/4 cups chocolate chunks

Preparations:

1. Combine butter, sugars, vanilla and eggs.
2. Separately, combine salt, flour and baking soda.
3. Mix both sets of ingredients.
4. Bake cookies at 375 for approximately 12 minutes.
