1 c unsalted butter
3/4 c granulated sugar
3/4 c light brown sugar, packed
2 large eggs
1 1/2 tsp pure vanilla extract
2 1/4 c all purpose flour
1 tsp baking soda
1 tsp salt
1 1/2 c semi sweet chocolate chips
1 c walnuts or pecans (optional)
1. Preheat the oven to 375°. Line two baking sheets with parchment paper. In a large mixing bowl beat the butter until soft. Add both sugars and beat until fluffy. Add both eggs one at a time until combined well. Pour in the vanilla extract and finish beating the batter, scraping down the sides of the bowl as well.
2. In a separate bowl whisk all the dry ingredients together- flour, baking soda, and salt.
3. Spill the dry ingredients into the batter. Continue beating the mixture until well combined. With a spatula gently mix in the chocolate chips, pecans and walnuts (optional).
