Blueberry Muffin is one of the best muffin varieties that you should try. Muffins refer to breads that are baked in small quantities. The dough is often placed in paper cups and baked in muffin or cupcake pans.
Blueberry Muffin or any muffin variety can sometimes be mistaken as cupcakes. Muffins and cupcakes are two different things. Muffins are less sweeter and it does not have any frosting. I do not really think that the distinction is important. All that matters is the taste. Call it Blueberry Muffin or Blueberry Cupcake — it should not be an issue as long as you are enjoying it.
