Ingredients
3/4 cup butter, at room temperature
1 cup packed brown sugar
1/4 cup sugar
1 large egg
2 tsp vanilla
2 cups all-purpose flour
1 tsp. baking soda
1/2 tsp. salt
1 cup chocolate chips
Directions
Preheat oven to 350F.
In a large bowl, beat the butter and sugars until pale and almost fluffy. Beat in the egg and vanilla.
Add the flour, baking soda and salt and stir or beat on low until almost combined; add the chocolate chips and stir just until blended.
Drop dough by the spoonful onto a parchment-lined (or buttered) sheet and bake for 10-14 minutes (depending on their size) until golden around the edges but still soft in the middle. Transfer to a wire rack to cool. Makes about 1 1/2 dozen large cookies.
Make-ahead tip:
To make the final result thick and chewy, refrigerate the dough overnight to develop the flavour and make an even thicker, chewier cookie; individual balls can also be frozen, then thawed on the cookie sheet as the oven preheats.
