chocolate chunk cookies

• 
  
• For our dinner party last night, my sister and I made my favorite chocolate chip cookies. They were moist, soft, and slightly sweet, and they perfectly complemented the coffee oreo icecream we had. We had a delightful time making our own icecream sandwiches!

• Here's the recipe (adopted from Martha Stewart): 
• 2 cups all-purpose flour
  
  
  1 teaspoon baking soda
