My favorite basic chocolate chip cookies

• 3/4 cup unsalted butter, melted
• 1 cup packed brown sugar 
• 1/2 cup white sugar
• 1 whole egg 
• 1 egg yolk
• 1 tbsp. vanilla extract
• 2 1/4 cups all purpose flour
• 1/2 tsp. salt
• 1/2 tsp. baking soda
• 2 cups milk or semi-sweet chocolate chips (or 1 cup milk chocolate chips, 1 cup m&m's)

1. Preheat oven to 325 degrees. Line cookie sheets with parchment paper.
2. In a large bowl, whisk together butter and sugars until combined (about 2 minute). Add in vanilla and egg + yolk. Whisk until smooth (about 30 seconds).
3. Add flour, salt, and baking soda to the bowl- stir together with a spatula or wooden spoon until there are no streaks of flour. Fold in the chocolate until evenly distributed.
4. Using a 1 1/2 T cookie scoop (or two spoons), drop dough 2 inches apart onto prepared cookie sheets. 
5. Bake for 11-13 minutes (cookies will look underdone, and bottoms will be barely golden). Cool on cookie sheet for 5 minutes.

Makes 3 dozen cookies.
