Chocolate chips or chocolate morsels are small chunks of sweetened chocolate, used as an ingredient in a number of desserts, in trail mix and less commonly in some breakfast foods such as pancakes. They are often manufactured as teardrop-shaped volumes with flat circular bases; another variety of chocolate chips have the shape of rectangular or square blocks. They are available in various sizes, usually less than 10 millimetres (0.39 in) in diameter.

A muffin is an individually portioned baked product; however, the term can refer to one of two distinct items: a part-raised flatbread that is baked and then cooked on a griddle, or a quickbread that is chemically leavened and then baked in a mold. While quickbread "American" muffins are often sweetened, there are savory varieties made with ingredients such as corn and cheese, and less sweet varieties like traditional bran muffins. The flatbread "English" variety is of British or other European derivation, and dates from at least the early 18th century, while the quickbread originated in North America during the 19th century. Both types are common worldwide today.
