Soft Chocolate Cookies

Step 1
Preheat oven to 350 degrees F (175 degrees C).

Step 2
Beat butter, white sugar, and brown sugar with an electric mixer in a large bowl until smooth. Beat in one egg until completely incorporated; beat in last egg along with vanilla extract. Combine flour, cocoa, baking soda, and salt in a bowl. Stir flour mixture into butter mixture until just incorporated; mix in chocolate chips.

Step 3
Roll dough into 2-inch balls, or drop spoonfuls of dough 2 inches apart, onto ungreased baking sheets.

Step 4
Bake in preheated oven until edges of cookies are firm, 10 to 12 minutes. Remove to wire racks. Dust warm cookies with confectioners' sugar, if desired.
