This was my mom's "go to" chocolate chip cookie recipe. The cookies are crisp on the edges and chewy in the center with a craggy, crackly surface and just the right amount of chocolate chips studded throughout.
Heat oven to 350° F, lightly grease (or line with parchment paper) two large baking sheets.
In a large mixing bowl, mix the brown sugar, butter, vanilla and eggs until well blended. There should be no visible lumps or streaks of butter remaining.
1 1/3 cup brown sugar, 3/4 cup butter, 1 tsp vanilla, 2 eggs
Add the flour, baking soda, salt, and chocolate chips. Stir just until combined - the dough will be soft.
2 1/4 cup flour, 1 tsp baking soda, 1/2 tsp salt, 12 oz chocolate chips
Drop the dough by rounded tablespoons (or use a cookie scoop for more consistent size/shape cookies) about 3 inches apart on the prepared baking sheets. If desired, press 3 to 4 more chocolate chips into each cookie before baking.
Bake in the pre-heated oven for about 10 minutes or until light brown.
Cool slightly on the pan before removing to a wire rack to finish cooling. Store in an air tight container at room temperature.
Notes
The original recipe called for 1 cup of M&M's and 1/2 cup of chopped nuts rather than the chocolate chips. Feel free to use 1 1/2 - 2 cups of your favorite cookie mix-ins if you're feeling creative or just want to mix things up a bit. My mom used the scoop and level method for measuring her ingredients. This is important to note when it comes to flour and using a kitchen scale rather than measuring cups. The official weight of a cup of flour is 120g, but if you scoop and level, you will get a cup of flour that typically weighs between 130g and 135g. I adjusted the metric version of this recipe to account for that difference.
