            Description
            These chocolate chocolate chip cookies are made with cocoa powder and chocolate chips to guarantee chocolaty flavor in every bite.
            Ingredients
            
                -  Sugar:              The recipe starts with 1 ½ cups white sugar.
-  Butter:             Beat the sugar with two sticks of softened butter.
-  Eggs:               Two eggs lend moisture and act as a binding agent, which means they help hold the dough together.
-  Vanilla:            Vanilla extract enhances the overall flavor of the chocolate chocolate chip cookies.
-  Flour:              All-purpose flour gives the cookie dough structure.
-  Cocoa powder:       They wouldn't be chocolate chocolate chip cookies without cocoa powder!
-  Baking soda:        Baking soda acts as a leavener, which means it helps the cookies rise.
-  Salt:               A pinch of salt enhances the overall flavor, but it won't make the cookies taste salty.
-  Chocolate chips:    You'll need two cups of semisweet chocolate chips.
-  Walnuts (optional): Walnuts are optional, but they add welcome crunch.
Steps
            
                - Gather all the ingredients and preheat the oven to 350 degrees F (175 degrees C).
- Beat sugar, butter, eggs, and vanilla in a large bowl until light and fluffy.
- Combine flour, cocoa powder, baking soda, and salt in another bowl; stir into butter mixture until well blended.
- Mix in chocolate chips and walnuts. Drop spoonfuls of dough 2 inches apart onto ungreased cookie sheets.
- Bake in the preheated oven just until set, 8 to 10 minutes. Cool slightly on the cookie sheets before transferring to wire racks to cool completely.
- Enjoy!
