What is This Children's Book Title?

My little brother had a book about a hen who baked a loaf of bread.

The story starts with flour or grain and ends with the freshly baked loaf. In between she collects all the ingredients and the other animals ask her what she is doing. She answers those questions and also asks, "Would you like to help me?" But no one does. Finally she is finished and the other animals ask the question again, except this time she adds, "I think I'll eat it all by myself!"
