Ingredients
>
1 cup (2 sticks) butter, softened
>
1 cup dark brown sugar
>
1/8 tsp salt
>
1 large egg
>
2 tsp vanilla extract
>
2 1/4 cups all-purpose flour
>
1 tsp baking powder
>
2/3 cup mini semisweet chocolate chips
Steps
1
Using a hand mixer or stand mixer, cream the butter, brown sugar, and salt 2–3 min., until fluffy. Add egg and extract. Combine well.
2
In batches, slowly mix in the flour and baking powder on low speed until combined. Stir in the chocolate chips. Shape dough into a roll about 2 inches in diameter. Wrap in wax paper or plastic wrap and refrigerate 2 hours, until firm.
3
Preheat oven to 350°F. Unwrap dough and cut into ½-inch slices. Arrange on parchment paper–lined cookie sheets, spacing 1 inch apart.
4
Bake cookies until golden, 10–15 min., switching racks halfway through. Let cool slightly and transfer cookies to a wire rack to fully cool.
