Chocolate chip refers to small, sweet pieces of chocolate that are often used in baking, especially in cookies. These delightful morsels melt slightly when baked, creating a gooey texture that many people love. The classic chocolate chip cookie is a favorite treat for both kids and adults, often enjoyed warm and fresh from the oven. The invention of chocolate chips is credited to Ruth Wakefield, who created the first chocolate chip cookie in the 1930s. She added chopped semi-sweet chocolate to her cookie dough, and the result was a delicious combination that has become a staple in many households. Today, chocolate chips come in various flavors and sizes, making them versatile for many desserts.
