These chocolate chip cookies get their name from winning first prize at the Brooklyn (Connecticut) Fair. The baker prefers soft and chewy cookies, hence the oven temperature being so low and the baking time so long, but, if you prefer a crispy cookie, try baking at 350 degrees for 10 to 12 minutes.
Preheat oven to 300 degrees. (If you prefer crispy cookies, preheat to 350 degrees.) Spray baking sheets with non-stick baking spray or use parchment paper.
In a small mixing bowl with a wire whisk, combine flour, baking soda, and salt. In a large mixing bowl, with electric mixer set at medium speed, combine brown and white sugars until blended. Combine butter with sugars and mix well. Add eggs and vanilla; mix with electric mixer until smooth and creamy. Add flour and chips, a little at a time each, and mix well using a sturdy wooden spoon. Drop dough onto prepared baking sheets by teaspoonfuls, or use a cookie-dough scoop. Bake for 22-25 minutes for chewy cookies, or about 10-12 minutes at 350 degrees for crispy cookies.
