I have been making cookies since I was probably about 8 years old and this is always my go to recipe (it was the first thing I made in my oven here). I should probably have it perfected by now but as I do not this recipe should get you close to what I make. (My tips are in the method)
INGREDIENTS
2 1/4 (350g) cups packed all-purpose flour
1 teaspoon baking soda
1 teaspoon salt
1 cup (220 g) softened butter or margarine
3/4 cup (150g) granulated sugar
2 large eggs
3/4 cup (160g) packed brown sugar
1 teaspoon vanilla extract
1 cup (170 g) semisweet chocolate chips
METHOD
Preheat oven to 375 °F (190°C). In a small bowl, combine flour, baking soda and salt. In a large mixing bowl, beat the butter, granulated sugar, brown sugar and vanilla extract until creamy. Add eggs, one at a time, beating well after each. Beat in the flour mixture little by little. Stir in morsels and nuts.
Chill dough for at least 30 min (better if overnight) then drop by rounded tablespoonfuls (or cookie scoop) onto baking sheets lined with parchment paper, 2 inches apart. Alternatively you could portion them out THEN chill them. This is to help keep them from spreading out as much while they bake, giving you a thicker, tender cookie.
Bake for 8 to 11 minutes or edges start to turn golden brown. Let cool on tray for a minute then slide the parchment paper off to cool completely (or at least until not scalding hot) before consuming them.
