1 tablespoon vanilla extract, such as nielsen-massey madagascar bourbon pure vanilla
2 eggs
4 cup all-purpose flour
2 teaspoon baking soda
1 3/4 teaspoon salt
1 teaspoon baking powder
1 teaspoon cream of tartar
12 ounce package semisweet chocolate chips
Directions
Preheat the oven to 350 degrees F.
Mix the butter, sugars, vanilla, and eggs in large bowl. Stir in the flour, baking soda, salt, baking powder, and cream of tartar. Stir in the chocolate chips. Drop with a #40 scoop (looks like a mini metal ice cream scoop) or a rounded measuring tablespoonful about 2 inches apart onto an ungreased insulated baking sheet. Bake until light brown, 12 to 15 minutes.
Cool slightly, then remove from baking sheet. Cool on wire rack.
Makes about 4 dozen crackly, chewy-crispy bakery-style cookies. They are wonderful!
